Overcurrent circuit breaker, 10kA BKH series 4P 80A characteristic C BKH 4P C80A

Overcurrent circuit breakers of the BKH series – reliable installation protection

The BKH series overcurrent circuit breaker is a protective element for the electrical installation against the effects of overloads and short circuits. The 4P model with a rated current of 80A and C characteristic provides effective protection in circuits requiring greater resistance to short-term current surges. The four-pole design makes the circuit breaker ideal for protecting polyphase electrical circuits.

Characteristics and application

BKH circuit breakers are characterized by high reliability and long service life. The C characteristic means that the circuit breaker reacts with a certain delay to an increase in current, which allows for trouble-free starting of devices with induction motors or other loads generating high starting currents. Therefore, the circuit breaker will not trip unnecessarily during normal operation of the device, but only in the event of a real threat.

Application will be found in installations:

• residential buildings,
• commercial buildings,
• industrial facilities,
• electrical switchboards.

Construction and mounting

The BKH 4P C80A circuit breaker is mounted on a 35mm DIN rail, which ensures quick and easy installation in distribution cabinets and electrical boxes. The solid construction and high-quality materials guarantee durability and resistance to environmental conditions. The circuit breaker has screw terminals allowing the connection of wires with a cross-section of up to 50mm². It is worth paying attention to compliance with IEC 60947-2 standard, which confirms compliance with strict safety requirements. The rated short-circuit breaking capacity is 10kA at 400V AC, which ensures effective protection in the event of a short circuit.
