Overcurrent circuit breaker, 10kA BKH series 3P 125A characteristic D BKH 3P D125A

Overcurrent circuit breakers BKH series – reliable installation protection

Overcurrent circuit breaker BKH 3P 125A is a three-pole installation circuit breaker designed to protect electrical circuits against overloads and short circuits. It is characterized by high efficiency and durability, making it an ideal solution for both domestic and industrial installations. Designed to work with circuits with a voltage of 400VAC and a rated current of 125A, it ensures safe and reliable operation of electrical devices.

Characteristics and application

A circuit breaker with characteristic D is characterized by a delayed reaction to short-term current increases, which is particularly important in the case of inductive loads, such as electric motors or transformers. This minimizes the risk of unnecessary tripping of the device during the start-up of these loads. BKH circuit breakers are widely used in residential, commercial buildings and in industry, where protection against the effects of overloads and short circuits is required. They provide effective protection of electrical circuits, protecting them from damage and fire.

Construction and product features

The BKH 3P 125A circuit breaker is made of high-quality materials, which guarantees its long-lasting and trouble-free operation. The three-pole construction provides uniform protection of all phases of the circuit. The short-circuit current of 10kA means that the circuit breaker can withstand high short-circuit currents without damage, ensuring the safety of the installation. It meets the requirements of IEC 60947-2 standard, which confirms its compliance with European safety standards. Mounting is done on a TH35 rail – a standard solution in electrical installations.
