ABB 2CDS252001R0064 S202-C6 2-Pole C-Curve 6A Miniature Circuit Breaker Technical Specifications and Applications

The S202-C6 combines thermal and electromechanical protection
mechanisms in a single device. The thermal release responds to
prolonged overload conditions, while the electromechanical release
provides rapid operation during short-circuit events. The resulting
protection arrangement makes the device suitable for properly
designed residential, commercial, and industrial electrical
installations.

ABB 2CDS252001R0064 Product Overview

The ABB 2CDS252001R0064 is identified as S202-C6 in the ABB S200
product family. The S202 designation indicates the two-pole
configuration, while C6 identifies the C tripping characteristic
and 6 A rated current. This complete identification is important
when selecting the correct circuit breaker because the S200 range
includes multiple pole configurations, current ratings, and
tripping characteristics.

The device is a miniature circuit breaker intended for low-voltage
electrical distribution and circuit protection. Its compact modular
construction allows it to be incorporated into distribution boards,
control cabinets, machinery panels, building electrical systems,
and other assemblies using compatible DIN-rail mounting.

ABB specifies the S200 range as current limiting miniature circuit
breakers. The product family uses separate thermal and
electromechanical tripping mechanisms to address overload and
short-circuit conditions. This combination provides two stages of
circuit protection within the same compact protective device.

Electrical Ratings

ABB 2CDS252001R0064 has a rated current of 6 A and a rated voltage
of 400 V AC. The product is designed for electrical systems in which
the operating voltage, prospective fault current, conductor
capacity, and connected load remain within the applicable
installation requirements.

The rated short-circuit capacity is 6 kA at 400 V AC according to
the applicable IEC product specification. The device also has a
rated insulation voltage of 440 V according to IEC/EN 60664-1 and
a rated impulse withstand voltage of 4 kV. These values provide
important reference information when integrating the circuit
breaker into a low-voltage electrical distribution system.

The electrical ratings should always be considered together with
the characteristics of the protected circuit. Conductor size,
installation method, ambient temperature, available short-circuit
current, load characteristics, and coordination with upstream and
downstream protective devices all influence the correct selection
of a miniature circuit breaker.

C Tripping Characteristic

The C characteristic is one of the defining features of the
S202-C6. C-curve miniature circuit breakers are generally selected
for circuits where connected equipment can produce moderate
starting or inrush currents. The C characteristic provides a
different instantaneous magnetic tripping response from B-curve
devices while maintaining thermal protection against sustained
overload.

This makes the C characteristic useful in selected control,
distribution, lighting, and equipment circuits where the connected
load characteristics are compatible with the protection
requirements. The choice between B, C, D, and other available
characteristics should be based on the actual circuit and load
conditions rather than the nominal current alone.

Overload and Short-Circuit Protection

The thermal tripping mechanism of ABB 2CDS252001R0064 provides
protection against sustained overcurrent. When current remains
above the appropriate operating level for a sufficient period,
the thermal mechanism responds and disconnects the protected
circuit. This delayed behavior distinguishes overload protection
from the faster response required for short-circuit faults.

The electromechanical tripping mechanism is designed to respond
rapidly to short-circuit currents. This function helps disconnect
the affected circuit and limit the consequences of a fault.
Because the S200 is a current-limiting product family, its
short-circuit performance is an important part of its overall
electrical protection function.

Technical Specifications

DIN-Rail Mounting and Construction

The S202-C6 is designed for DIN-rail mounting and can be installed
on compatible TH35 rails according to IEC 60715. Its 35 mm width,
88 mm height, and 69 mm built-in depth provide a compact form
factor for modular distribution assemblies. The two-pole design
occupies limited panel space while providing protection for the
corresponding electrical circuit.

The circuit breaker uses screw terminals with a cylinder-lift
terminal design. ABB documentation specifies a tightening torque
of 2.8 N·m. The connecting capacity accommodates a range of
conductor sizes depending on whether rigid, stranded, flexible,
ferruled, or busbar connections are used.

The product can be mounted in different positions according to
the installation arrangement. Proper terminal preparation,
conductor sizing, tightening torque, and enclosure design should
be observed when integrating the device into an electrical panel.

Operating Environment

The documented operating ambient temperature range for the
S202-C6 is approximately -25 °C to +55 °C, while the storage
temperature range is approximately -40 °C to +70 °C. These values
are useful when determining whether the installation environment
is suitable for the circuit breaker.

The circuit breaker has an IP20 degree of protection, while
installation inside an enclosure with an appropriate cover can
provide a higher overall enclosure protection level. Environmental
conditions, ventilation, thermal loading, and the arrangement of
adjacent devices should be considered when designing a complete
distribution assembly.

Standards and Electrical Compliance

ABB identifies the S200 miniature circuit breaker family with
applicable IEC and EN requirements, including IEC/EN 60898-1 and
IEC/EN 60947-2. The S200 family is intended for use across
residential, commercial, and industrial electrical applications
when the selected device matches the requirements of the
installation.

The S202-C6 also has a rated impulse withstand voltage of 4 kV and
a rated insulation voltage of 440 V. Its energy-limiting
classification and short-circuit characteristics are relevant
when engineers evaluate the device as part of a coordinated
electrical protection system.

Accessory Compatibility

The ABB S200 platform supports compatible auxiliary accessories
that can extend the functionality of the miniature circuit
breaker. For example, bottom-fitting auxiliary contacts can be
used with compatible S200 devices where additional electrical
signaling or status indication is required.

Accessory selection should be based on the exact S202-C6
configuration and the intended electrical function. Mechanical
compatibility, terminal arrangement, electrical ratings, and
installation requirements should all be checked before adding
accessories to the circuit breaker assembly.

Applications of ABB 2CDS252001R0064

ABB 2CDS252001R0064 can be used in electrical distribution and
control circuits where a two-pole, 6 A miniature circuit breaker
with a C tripping characteristic is required. Potential
applications include building distribution boards, industrial
control cabinets, machinery electrical systems, auxiliary
circuits, commercial installations, and selected residential
circuits.

The C characteristic is particularly relevant when the protected
circuit includes equipment that can produce a moderate starting
current. However, the actual suitability depends on the load,
wiring system, fault level, and applicable protection rules.
Correct circuit breaker selection should therefore be based on
the complete electrical design rather than the product’s current
rating alone.

Product Identification

The complete ABB product number is
2CDS252001R0064. The corresponding extended
product type is S202-C6. ABB documentation also
identifies the product with EAN 4016779465502.
Keeping the complete product number and S202-C6 designation
together helps distinguish this circuit breaker from other S200
variants with different current ratings, pole configurations,
or tripping characteristics.

ABB 2CDS252001R0064 is therefore a two-pole S202-C6 miniature
circuit breaker with a 6 A rated current and C tripping
characteristic. Its thermal overload protection,
electromechanical short-circuit protection, DIN-rail mounting,
compact construction, and defined 6 kA short-circuit capacity
make it a practical protective component for appropriately
designed low-voltage electrical distribution and control systems.
