Circuit breakers are a type of switch designed to protect electrical devices or circuits from short circuit events or overload conditions. The JLE-1-1REC4-52-3-F1-250 is a miniaturized trip unit designed to protect branch and feeder circuits from overloads and short circuits. It is designed to provide overcurrent protection and is suitable for industrial or commercial applications, providing instantaneous protection.

Function

The JLE-1-1REC4-52-3-F1-250 provides short circuit protection in circuits up to 600V AC or 250V DC and is capable of handling inrush currents up to 13 times the rated current. It is designed to trip instantly at current levels above 200A and at adjustable current levels between 10A and 200A. It has an adjustable thermal magnetic trip set point from 0.16-1.1 times the rated current. The trip unit is designed to fit into standard circuit breakers that use a size 2 or size 3 mounting footprint. The trip unit comes with an indicator light that will illuminate if the breaker has tripped due to an overload or short circuit.

Operation and Safety Features

The JLE-1-1REC4-52-3-F1-250 protects circuits from both short circuits and overloads. In the event of an overload, the trip unit will instantly trip the circuit breaker with no manual resetting required. This feature ensures the circuit breaker will reliably protect against overloads. The indicator light on the trip will illuminate when the breaker is tripped, both for overloads and short circuit events, which gives clear feedback to the user that there has been an issue. The trip unit also features settable short circuit protection for adjustable current levels between 10A and 200A. This allows the user to customize the protection to their specific requirements.

Connectivity and Compatibility

The JLE-1-1REC4-52-3-F1-250 is designed to fit into standard circuit breakers that use a size 2 or size 3 mounting footprint. It is designed to work with a variety of circuit breakers, including 1pole, 2pole, 3pole and multi-pole configurations. The trip unit is UL listed and is RoHS compliant, making it suitable for use in commercial or industrial applications.

Application Field and Working Principle

The JLE-1-1REC4-52-3-F1-250 is an ideal solution for protecting branch and feeder circuits from overcurrent events. The adjustable current setting allows the user to customize the protection, while the instantaneous trip response and indicator light provides feedback indicating a problem has occurred. The trip unit fits into a size 2 or size 3 frame and is compatible with a variety of circuits breakers, making it suitable for a wide range of applications. In the event of an overload or short circuit event, the trip unit will instantly trip the circuit breaker, providing protection to both the circuit and the device.
