Overcurrent circuit breaker, 2P, K characteristic, 2A, 10kA, AC | SU202M-K2 2CDS272337R0277

Overcurrent circuit breaker – reliable protection for your installation

This two-pole overcurrent circuit breaker with K characteristic is a key element ensuring safety in every electrical installation. Designed to protect circuits against overloads and short circuits, it is perfect for both domestic and professional applications. The K characteristic means that the circuit breaker reacts slightly slower to short-term current surges, which is particularly important when protecting devices with motors or other loads with high inrush current.

Solid construction and high performance

This circuit breaker is characterized by a high short-circuit breaking capacity – up to 15 kA at 400 V (according to IEC 60947-2) and 11.2 kA (according to EN 60898). This ensures effective protection of the circuit against damage caused by sudden current flows. Its compact size – only 2 modules wide – allows for easy mounting in electrical distribution boards. Made of high-quality materials, it guarantees long-lasting and trouble-free operation in a wide range of ambient temperatures (-25°C to +55°C).

Universal application and easy installation

The circuit breaker is designed to operate in installations with a rated voltage of 440 V and a frequency of 50-60 Hz. It accepts solid wire cross-sections up to 35 mm² and stranded wires up to 25 mm², providing great flexibility when connecting different types of cables. Mounting is done on a standard TH35 rail, and the IP20 degree of protection provides basic protection against accidental contact. The possibility of expanding with additional accessories increases functionality and adaptation to individual installation needs. The energy limitation class is 3, which demonstrates its effectiveness in mitigating the effects of short circuits.
