Circuit Breakers

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. Circuit breakers may also be used for controlling a circuit, such as illuminating a light or fan to provide control. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.

LELB1-1RS4-37332-60 is a specific type of circuit breaker that is used in various applications and its working principle is based on the concept of an electromagnet, the LELB1-1RS4-37332-60 circuit breaker consists of an electromagnet that is connected to the input source, a moving armature and an arc suppressor.

Applications

The LELB1-1RS4-37332-60 circuit breaker is a low-voltage circuit breaker designed primarily for industrial purposes. It was designed for medium-voltage applications and is used for protection against short circuits, earth faults and overloads. Its main applications include power and lighting, distribution and protection, traction systems and other industrial applications.

The LELB1-1RS4-37332-60 is suitable for mounting in industrial switch boards and electrical panels, providing reliable overcurrent protection. It is also suitable for a variety of installations, including automobile manufacturing, shipping, chemical and petrochemical industries, power plants and water/sewage systems.

Working Principle

The LELB1-1RS4-37332-60 circuit breaker is based on the principle of an electromagnet. When a short circuit fault or overload occurs, the contacts of the circuit breaker open, thus interrupting power supply to the affected circuit.

When an overload or short circuit occurs, the electromagnet becomes energized and moves the moving armature away from the contacts, thus interrupting power supply to the circuit. In order to control the current flow, the circuit breaker is also equipped with an Arc Suppressor. When the current rises above a predetermined level, the arc suppressor limits the current and thus prevents an arc from forming between the moving armature and the contacts. This prevents the current from further damaging the circuit.

The LELB1-1RS4-37332-60 circuit breaker is a reliable and efficient device used in many industrial applications. Its primary purpose is to protect electrical circuits against overloads, short circuits and earth faults. It is also equipped with an arc suppressor, which allows it to limit the current flow when an overload or short circuit occurs. This helps to reduce the damage caused by the faults.
