Circuit breakers are an important component of electrical systems, and the form and model adopted for specific applications often depend on specific environmental and safety requirements. The LELHPK11-1REC4-36862-150-V is one such circuit breaker. This article will discuss its application field and working principle in order to better understand its usage.

In terms of application, the LELHPK11-1REC4-36862-150-V is primarily used in AC low voltage distribution systems. It features a rated current of 500A and a rated AC voltage of up to 690V. It is also equipped with a three-pole, high interrupting capacity of 10kA. This makes it suitable for a variety of applications, such as household installations, commercial buildings, and industrial premises.

In terms of working principle, the LELHPK11-1REC4-36862-150-V is a combination of 2 independent parts, the contact system and its overcurrent protection system. Its contact loads are direct current. The electrical contact action works in a way that allows current to flow through the system when the system is in an open position, and current to be interrupted when the system is in a close position.

The other part of the system is the overcurrent protection system, which detects overcurrents in the circuit and automatically trips the circuitbreaker. This system consists of a magnetic coil, which is activated when an overcurrent is detected in the circuit. The magnetic coil triggers a trip mechanism which trips the breaker. This allows a quick yet safe disconnection of the circuit.

Overall, the LELHPK11-1REC4-36862-150-V circuit breaker is an ideal choice for AC low voltage distribution systems, due to its combination of high interrupting capacity, rated current, and rated AC voltage. Its two-piece construction combines a contact system and overcurrent protection system, allowing it to efficiently and safely interrupt overcurrents in the circuit.
