Technical Specifications

Advanced Protection Technology

The ABB 2CDS252001R0104 uses two independent protection mechanisms to achieve reliable circuit protection. The thermal release mechanism provides delayed response during overload conditions, allowing temporary current variations while preventing excessive heating of electrical conductors. This function protects wiring systems and connected equipment from damage caused by continuous overcurrent.

The electromagnetic release mechanism provides rapid response during short-circuit conditions. When a sudden fault current occurs, the magnetic tripping system activates quickly to isolate the affected circuit. This combination of thermal and magnetic protection allows the ABB S202-C10 to provide dependable performance in a wide range of electrical applications.

C Curve Tripping Characteristic

The C tripping characteristic of the ABB 2CDS252001R0104 is designed for circuits where moderate inrush currents may occur during normal operation. Compared with lower sensitivity characteristics, the C curve allows temporary startup currents generated by certain electrical loads while still maintaining effective protection against overload and short-circuit conditions.

This characteristic makes the ABB S202-C10 suitable for a variety of applications including lighting distribution systems, control circuits, small motors, power supplies and general industrial equipment. By providing a balanced response between operational continuity and fault protection, the breaker helps reduce unnecessary interruptions while maintaining electrical safety.
