Overcurrent circuit breaker, 2P, C characteristic, 2A, 10kA, AC | S202M-C2 2CDS272001R0024

Overcurrent circuit breaker, two-pole, with C characteristic and rated current of 2A is a reliable protection for electrical installations. Designed to protect circuits against overloads and short circuits, it works well in both TN systems and IT systems. Its compact design – occupies only 2 modules on the TH rail – makes installation easier even in crowded distribution boards.

Protection and functionality

This circuit breaker, designated as S202M-C2, is distinguished by its high short-circuit breaking capacity, amounting to 10kA at 400V and 25kA at 230V (according to IEC 60947-2). Characteristic C provides delayed tripping, which is particularly important for circuits with loads generating inrush currents during start-up – such as motors or transformers. This avoids unnecessary tripping of the circuit breaker during normal operation of the devices. Energy limitation class 3 and surge category III guarantee effective protection against the effects of overvoltage.

Installation and compatibility

The circuit breaker is intended for mounting on a standard TH35 rail. It accepts solid conductors with a cross-section from 0.75 mm² to 35 mm² and stranded conductors from 0.75 mm² to 25 mm². Its IP20 degree of protection provides basic protection against accidental contact. Suitable for operation in ambient temperature from -25°C to +55°C, it will perform well in various environmental conditions. Power losses are only 3.6W, which translates into efficient energy use. The rated impulse withstand voltage Uimp is as high as 4kV, which further increases its resistance to interference.

Key features at a glance:
