Overcurrent circuit breaker, 2P, C characteristic, 20A, 10kA, AC/DC | S202M-C20UC 2CDS272061R0204

Protection and reliability in your electrical installation

This two-pole overcurrent circuit breaker from ABB's Standard series is a key element ensuring safety and continuity in electrical circuits. Designed to protect against overloads and short circuits, it performs well in both AC and DC installations. Its compact design (2 module width) simplifies installation in distribution boards, and the C characteristic provides effective protection for devices with higher inrush current.

Functionality and technical parameters

The S202M-C20UC circuit breaker is designed for a wide range of applications – from residential buildings, through commercial properties, to industrial facilities. A rated current of 20A makes it an ideal choice for protecting circuits with medium loads. The rated short-circuit breaking capacity of 10kA (at 230V and 400V) guarantees a quick response in the event of a failure, minimizing the risk of damage and fire. Additionally, high resistance to interference (overvoltage category III and IP20 protection) ensures reliable operation even in difficult environmental conditions.

Installation and compatibility

The circuit breaker is mounted on a standard TH35 rail, which greatly simplifies the installation process. It accepts both solid (up to 35 mm²) and stranded (up to 25 mm²) wires, providing flexibility in wire selection. A wide operating temperature range (0°C to 55°C) allows it to be used in various environments. The circuit breaker complies with IEC/EN 60898-1 and IEC/EN 60947-2 standards, confirming its safety and high quality of workmanship. The C characteristic allows for trouble-free starting of devices with motors or other elements generating high inrush current – the circuit breaker will not trip unnecessarily during normal device operation.
