Circuit breakers are electrical devices designed to protect, interrupt or manage electrical circuits which have become overloaded or faulted. The LELK1-1REC4-30079-3 circuit breaker is a heavy duty breaker designed for use in industrial and commercial settings.

The LELK1-1REC4-30079-3 circuit breaker is a single or three-phase breaker which can be either manual or automatic. It has a current rating of up to 300 Amps, and is designed for both indoor and outdoor applications. The breaker features a thermal magnetic trip unit which provides short circuit protection at currents up to 36kA. It also provides overload protection, preventing circuits from becoming overloaded and causing damage to equipment.

This circuit breaker is ideal for a wide range of applications including machine control, process control, HVAC, elevators, and other power distribution systems. It is typically used in industrial and commercial settings such as factories, warehouses, schools, and other facilities.

The working principle of the LELK1-1REC4-30079-3 circuit breaker is based on the thermal-magnetic trip unit. This unit measures current flow and will trip the breaker if the current exceeds its rating. The thermal-magnetic trip unit also provides short circuit and overload protection.

When the current exceeds the breaker\'s rating, the magnetic field generated by the current will act on the internal trip coil. This will cause the breaker trip coil to become magnetized and will cause the breaker to trip. The trip coil also includes a thermal element that will cause the breaker to trip if the current exceeds its rating for a sustained period of time.

When the breaker trips, the contacts of the breaker move apart and interrupt the circuit. This will prevent further current flow and protect the circuit from damage. The breaker will remain tripped until it is manually reset or until the fault is cleared from the system.

The LELK1-1REC4-30079-3 circuit breaker is a reliable and durable breaker designed for a variety of applications. It provides short circuit and overload protection, as well as manual or automatic operation. This breaker is ideal for industrial and commercial settings and is designed for both indoor and outdoor applications.
