Circuit Breakers are safety devices used in electrical system and equipment to protect them and reduce their likelihood of faults. The IULK2-1REC4-23790-1 is a type of circuit breaker designed to provide protection against short circuit and overload faults on circuit systems.

Application Field

The IULK2-1REC4-23790-1 circuit breaker is suitable for low voltage AC circuits, with a rated voltage of up to 690V and a rated current of up to 400A. It was developed for use in commercial and industrial buildings with applications ranging from lighting and wiring to electric motors and machinery. In addition, it can be used in distribution networks within residential buildings.

Working Principle

The circuit breaker operates on the principle of over current protection. It monitors the current flow through the circuit and if it exceeds the pre-set level, the breaker will open, cutting off the power and de-energizing the circuit. The IULK2-1REC4-23790-1 is designed to respond quickly to prevent excessive heat build up and damage to the circuit components in the event of an overload or short circuit.

The circuit breaker is designed with an adjustable trip current setting which allows the user to set the trip current to a level suitable for the specific application. This can be set manually or it can be set automatically by utilizing an electronic trip mechanism, depending on the requirements of the application.

In addition, the circuit breaker features a thermal-magnetic tripping mechanism. This is a combination of both thermal and magnetic sensors, which provide a second layer of protection against high current. The thermal element works by detecting increases in temperature in the circuit breaker. If the temperature reaches a certain level, the trip mechanism will activate, disconnecting the circuit from the power supply. The magnetic element uses a sensing coil to monitor the current in the circuit. As the current increases, the coil generates a magnetic field which activates the trip mechanism.

Design Features

The IULK2-1REC4-23790-1 circuit breaker also features a kinetic energy storage system. This works by storing kinetic energy which is then released during a fault to protect against arc faults and extend the life of the breaker. It also has a screw-less design, allowing for easy installation and maintenance. Other features include adjustable trip current setting, adjustable time-delay, adjustable electrical contacts, and a manual override switch.

The IULK2-1REC4-23790-1 circuit breaker is a reliable and robust solution for over current and short circuit protection in industrial, commercial and residential applications. It provides a range of design features and adjustable settings to ensure an optimal level of protection, while also being easy to install, maintain and replace.
