Overcurrent circuit breaker, 3P, K characteristic, 32A, 10kA, AC/DC | S203M-K32UC 2CDS273061R0537

Overcurrent circuit breaker 3P – reliable installation protection

This three-pole overcurrent circuit breaker with K characteristic is a key element of every safe and efficient electrical installation. It provides effective protection against overloads and short circuits, minimizing the risk of damage and fires. Its versatility – operation in both AC and DC circuits – makes it an ideal choice for various applications, both in residential and commercial buildings.

Design and parameters for professionals

The circuit breaker is characterized by a high short-circuit breaking capacity, reaching 10 kA at 400 V and 25 kA at 230 V. The K characteristic means delayed tripping, which is particularly important for loads with high inrush current, such as motors or transformers. This avoids unnecessary tripping of the circuit breaker during normal operation of devices. A width of 3 modules simplifies installation in distribution boards. The wire cross-section from 0.75 to 25 mm² (stranded) and 0.75 to 35 mm² (solid) ensures compatibility with most standard installations. Energy limitation class 3 guarantees adequate protection in the event of an electric arc.

Advantages for installers and end users
