Overcurrent circuit breaker, 10kA BKH series 3P 80A characteristic D BKH 3P D80A

Overcurrent circuit breakers of the BKH series – reliable protection of installations

The BKH 3P 80A circuit breaker with D characteristic is a protective element designed to protect electrical circuits against overloads and short circuits. It is a three-pole circuit breaker that can be used in both domestic and industrial installations. It is characterized by high reliability and durability, ensuring safe operation of the electrical installation.

Characteristics and application

The BKH circuit breaker with D characteristic is distinguished by a delayed response time in case of overloads. This means that it allows for short-term exceeding of the rated current without disconnecting the circuit – which is particularly important for devices with electric motors or other loads with high inrush current. This minimizes the risk of unnecessary tripping of the installation when starting such devices. These circuit breakers are ideal for protecting circuits powering heating devices, lighting and other loads requiring a stable power supply.

Construction and parameters

The BKH 3P 80A circuit breaker has been designed with easy installation and convenient operation in mind. Compact dimensions (63x81x81 mm) allow for installation in standard electrical distribution boards. The rated current of 80A and the short-circuit breaking capacity of up to 10kA guarantee effective protection even in the event of serious disturbances in the electrical network. Compliance with IEC 60898 and IEC 60947-2 standards confirms the high quality and safety of the product. Made of high-quality materials, it ensures long-lasting and trouble-free operation.
