ABB 1SAM350000R1007 MS132-2.5 Manual Motor Starter

The ABB 1SAM350000R1007 MS132-2.5 manual motor starter is designed to provide reliable switching, protection and isolation for low-power industrial motors operating in demanding environments. As part of the ABB MS132 product family, this compact motor protection device combines thermal overload protection, magnetic short-circuit protection and manual switching functionality within a single housing, reducing panel complexity while improving operational reliability.

Industrial motors frequently encounter overload conditions, phase imbalance and electrical faults that can significantly reduce service life and cause costly production interruptions. The MS132-2.5 has been developed to minimize these risks by delivering fast and accurate protection while maintaining stable operation under normal load conditions.

Adjustable Current Protection Range

The ABB 1SAM350000R1007 features an adjustable current setting range from 1.6A to 2.5A, allowing precise matching with motor full-load current requirements. The front adjustment dial enables quick configuration during installation and commissioning while reducing engineering complexity.

Accurate overload adjustment helps improve motor protection performance and minimizes unnecessary trips caused by temporary current peaks that may occur during normal startup or load fluctuations.

Integrated Thermal Overload Protection

The thermal protection system continuously monitors motor current and disconnects the circuit whenever overload conditions persist for extended periods. This function protects motor windings against excessive heat generation and insulation degradation.

The Class 10A tripping characteristic provides effective protection for most industrial motor applications while still allowing sufficient starting current during normal motor acceleration periods.

Magnetic Short-Circuit Protection

The MS132-2.5 includes an instantaneous magnetic trip mechanism designed to react rapidly to severe short-circuit conditions. The fixed instantaneous trip level of approximately 31.3A allows fast fault interruption and limits damage to motors, cables and associated equipment.

The device provides high short-circuit breaking capacity up to 100kA at rated voltages, making it suitable for installation in industrial distribution systems with elevated fault levels.

Phase Failure Sensitivity

Three-phase motors are highly sensitive to phase loss conditions, which may lead to overheating and mechanical stress. The ABB 1SAM350000R1007 incorporates phase failure sensitivity to detect abnormal operating conditions and disconnect the motor before damage occurs.

This protection function is especially important in pumping systems, ventilation equipment and continuous production machinery where unexpected motor failure can result in significant downtime.

Manual Switching and Isolation

The device serves as both a protection unit and a manual motor switch. Operators can safely start and stop motors using the rotary operating handle while clearly observing the operating status through the integrated ON, OFF and TRIP indicators.

The isolation function simplifies maintenance activities by providing a safe disconnect point for service personnel working on downstream equipment.

Compact DIN Rail Installation

Modern control cabinets require efficient use of installation space. With a housing width of only 45 mm, the ABB MS132-2.5 offers excellent space optimization without compromising protection performance.

The unit supports installation on standard TH35 DIN rails according to IEC 60715 standards, simplifying integration into both new projects and retrofit applications.

Reliable Performance in Industrial Environments

The ABB 1SAM350000R1007 is engineered for continuous operation under demanding environmental conditions. Temperature compensation technology maintains accurate trip characteristics over a broad temperature range and ensures consistent protection behavior.

The robust housing design provides resistance against vibration and mechanical stress commonly encountered in industrial production facilities and machine installations.

Accessory Compatibility

The MS132 product family supports numerous accessory modules that increase flexibility and simplify integration into advanced automation systems. Auxiliary contacts, signaling contacts, shunt trips and undervoltage releases can be installed according to application requirements.

These accessories allow the motor starter to be used not only as a standalone protection device but also as part of larger motor control centers and intelligent automation architectures.
