Circuit breakers are essential components for buildings all around the world. Protection against electrical faults is provided by the use of circuit breakers, ranging from household fuses to large-capacity current-limiting fuses for industrial networks. The JLE-2-1-53-3-F0-250 circuit breaker is typically used in residential installations, such as homes, small businesses, and similar facilities. It is designed to protect against overloads, short circuits, and ground fault conditions which could otherwise result in fire or hazard to personnel.

The JLE-2-1-53-3-F0-250 circuit breaker is a double pole, fixed trip, rated-load, general-purpose circuit breaker. This breaker is designed to switch loads up to 250 amps. The trip settings are non-adjustable and the line and load terminals are capable of accepting both copper and aluminum conductors. It also includes a lockout handle, which locks the switch in the off position. This prevents accidental reactivation of the breaker and is commonly used in facilities to protect maintenance personnel.

The working principle of the JLE-2-1-53-3-F0-250 circuit breaker is based around the operation of the trip unit. The integrated trip unit is designed to detect any overcurrent condition, and if triggered, will disallow the breaker from resupplying power to the associated load.

The integrated trip unit operates by monitoring the current in the associated circuits. If a short circuit or overload condition occurs, the trip unit will detect the excessive flow of current and, in turn, activate a bimetallic thermal-magnetic strip to trip the circuit. This current rating is preset at the factory and the integrated trip unit is designed to remain operational for the full life of the breaker.

This breaker also includes a shunt trip that is operated by the application of an external power source to the spade terminal. This allows the breaker to be used in applications where it is needed to break current in multiple locations or in the event of an emergency. This can be done by pressing a button or sending a signal from a fire alarm or control system.

In general, the JLE-2-1-53-3-F0-250 circuit breaker is used for residential and commercial applications, where it is necessary to protect electrical circuits and personnel from damaging over current, short circuit, ground fault, and over temperature conditions. This breaker is designed for use with 600V AC systems and provides reliable protection against these faults.
