Overcurrent circuit breaker, 4P, C characteristic, 50A, 6kA, AC | S204-C50 2CDS254001R0504

Electrical installation protection with ABB S204-C50 circuit breaker

This four-pole overcurrent circuit breaker with C characteristic is a reliable element protecting electrical circuits against the effects of overloads and short circuits. It will work well both in home and industrial installations where high breaking capacity is required. The S204-C50 circuit breaker is compatible with a wide range of additional equipment, allowing it to be adapted to the specific needs of the installation. Mounting is done on a standard DIN rail.

Characteristics and application

The S204-C50 overcurrent circuit breaker is characterized by a rated current of 50A and a C characteristic, which means it allows for short-term overloads, typical for devices with induction motors (e.g., refrigerators, washing machines). This ensures stable operation of the installation without unnecessary tripping in the event of short-term load surges. The rated breaking capacity of 6kA at 400V (according to EN 60898) and 10kA at 400V (according to IEC 60947-2) guarantees effective protection against the effects of short circuits.

Construction and technical parameters

The circuit breaker is designed for durability and reliability. It has a protection degree of IP20, which protects it against accidental contact. A width of 4 modules makes it easy to mount in standard distribution boards. Wires can be connected using solid wires with a cross-section from 0.75 mm² to 35 mm² or stranded wires from 0.75 mm² to 25 mm². The ambient temperature in operating conditions is in the range of -25°C to +55°C, which ensures its proper operation in various environmental conditions. The energy limitation class is 3 – it provides adequate protection in the event of an electric arc. The rated impulse withstand voltage is as high as 4kV.
