Circuit breakers are an essential component in any electrical system, and the LELBX1-35527-20-V model is no exception. This type of circuit breaker is designed to protect against overloads and short circuits, while providing reliable circuit protection. It is a high-performance, solid-state circuit breaker with a rated voltage of 12-15kV and current ratings of up to 2,5kA.

The circuit breaker features a segmented type trip unit for improved protection and an optimized latch allowing for a high number of reconfigurations.

The circuit breaker has a pole-soft trip operation with its positive trip performance ensuring short circuit protection. The design also provides safety against ill-timed trips and false shuts, which can cause inconvenient downtime or significant damage to the electrical system.

The circuit breaker also has internal arc protection which prevents contact arcing when exposed to fault conditions. This provides additional protection to the electrical system and the people working on it.

When it comes to working principles, the LELBX1-35527-20-V circuit breaker has a single-pole actuating principle. When a current overload or short circuit occurs, a triac on the breaker trips, which causes the mechanism to disconnect the power. The reset time of the breaker depends on the severity of the overcurrent.

The LELBX1-35527-20-V circuit breaker is widely used in the transmission and distribution of large electrical systems. It is typically employed in the construction of new power stations and substations, as well as in the replacement and updating of existing systems. It can be easily installed in AC and DC circuits, helping to ensure reliable and secure power supply.

The LELBX1-35527-20-V circuit breaker is highly durable and reliable, making it a popular choice for a variety of applications. Its triac and internal arc protection provide excellent protection against overcurrent and short circuits, while its pole-soft trip operation ensures safe operation and prevents unsafe or ill-timed trips.

In conclusion, the LELBX1-35527-20-V circuit breaker is an excellent choice for any application where reliable protection of electrical circuits, high current overloads and short circuits is required. Its single pole actuating principle and internal arc protection provide excellent protection, while its pole-soft trip operation ensures reliable operation and prevents false shuts or ill-timed trips.
