Circuit breakers are an essential part of any electrical system. The LELB1-1REC4-37715-75-V is a type of circuit breaker specialized for industrial applications. This article will explore the application field and working principle of the LELB1-1REC4-37715-75-V circuit breaker.

The LELB1-1REC4-37715-75-V circuit breaker is used in industrial control and electrical distribution systems. It is designed for use in systems of up to 7700 A at 600V. It has a specifically designed insulation and current-limiting features that make it ideal for short-circuit protection, motor control, and lighting control applications. It is often used in combination with a contactor to provide a complete overcurrent protection system.

The design of the LELB1-1REC4-37715-75-V circuit breaker includes an insulated arc-chute. This arc-chute is designed to contain and extinguish any arcs that are generated due to the interruption of the current and protects the device from electrical damage. It also has a double-break mechanism and a magnetic-trip system that helps minimize arcing and enable faster tripping times. The circuit breaker also includes a separate trip control unit, which can be set to automatically trip the breaker at a set current level if an overload is detected.

The working principle of the LELB1-1REC4-37715-75-V circuit breaker is the same as that of any other circuit breaker. When a fault occurs, the current in the system is interrupted, causing an arc to form between the contacts. The arc-chute in the circuit breaker helps to contain this arc to prevent further damage while the double-break mechanism helps to quickly extinguish it. The magnetic trip system creates a strong magnetic field which trips the breaker when the current reaches a certain level, limiting the amount of damage caused by the fault and protecting the system.

In summary, the LELB1-1REC4-37715-75-V circuit breaker is a type of circuit breaker specialized for industrial applications. It is designed for use in systems of up to 7700 A at 600V and is often used in combination with a contactor to provide a complete overcurrent protection system. The device includes an arc-chute, double-break mechanism, and magnetic-trip system, which make it ideal for short-circuit protection, motor control, and lighting control applications. Its working principle is the same as that of any other circuit breaker and includes the containment and extinguishing of arcs created by a fault.
