LELHPK11-2REC4-32773-25 Circuit Protection

Circuit Breakers are essential protective components in electrical systems, as they are used to prevent overcurrents and short circuits that can occur on electrical networks. Circuit Breakers are classifed by their type, breaking capacity and interfering current. LELHPK11-2REC4-32773-25 is a type of circuit breaker which has a distinct application field and working principle.

Application Field

The LELHPK11-2REC4-32773-25 is designed for use in residential and commercial environments. It is suitable for AC50/60Hz, up to 1000V single-phase and three-phase switching power supply systems. This circuit breaker is suitable for use as lighting, circuits, motors, and other parts of the circuit that requires overcurrent protection. The circuit breaker can also be used for cables, transformers and other components in power systems.

Working Principle

LELHPK11-2REC4-32773-25 is an electromagnetic-type circuit breaker. It works by the principle of using electromagnetism to open and close the circuit. When an overcurrent or short circuit occurs, the sensitivity of the contact and contacts of the circuit breaker will be automatically adjusted. When the contact pressure reaches the prescribed value, the contact will be opened and the electric current will be cut off. This will help prevent the circuit from being damaged due to overcurrent or short circuit.

When the current is restored to the rated value, the contact of the circuit breaker will automatically close, putting the circuit back into normal operation. Since the operation of the circuit breaker mainly depends on adjusting the contact pressure, it is particularly important to adjust the contact pressure regularly.

In addition to the contact pressure adjustment, the LELHPK11-2REC4-32773-25 circuit breaker also comes equipped with overload and short circuit protective functions. If an overload occurs, the contacts will open and the circuit will be disconnected in order to protect the circuit components from damage. When a short circuit occurs, the contacts will also open and the current will be cut off.

LELHPK11-2REC4-32773-25 is a reliable circuit breaker with high mechanical and electrical life, enabling it to be used for many years. It also has a large tripping capacity, which enables it to open the circuit reliably under different current levels.
