Circuit breakers are safety devices that protect electrical circuits from damage caused by overloads and short circuits. Circuit breakers are typically found in power distribution systems, industrial control systems, and in other applications where current has the potential to cause damage and disruption. The IULK2-38807-75 is a type of circuit breaker that is used in a variety of applications. This article will discuss the IULK2-38807-75’s application field and working principle.

Application Field of the IULK2-38807-75

The IULK2-38807-75 is a thermal-magnetic circuit breaker, which means that it is suitable for all network elements that require a low level of protection. It is primarily used in circuits for direct current control, distribution boards, and control assemblies in general. It also can be used in direct current motors, rectifier systems, and energy recovery systems. The IULK2-38807-75 can be mounted in two different ways—either in a flush-mounting box or on a mounting rail.

This type of circuit breaker is certified by UL1077, meaning it has gone through the compliance tests required by Underwriters Laboratories and other safety organizations. The IULK2-38807-75 offers class C protection, making it suitable for residential, commercial, and industrial applications. This circuit breaker can be used to protect lighting, air conditioners, pumps, power tools, and other electrical devices. It offers a wide variety of features and benefits, making it a suitable choice for a number of applications.

Working Principle of the IULK2-38807-75

The working principle of the IULK2-38807-75 is based on the concept of thermal-magnetic protection. Thermal-magnetic protection is a type of protection that uses both the heat generated by current through the circuit and the magnetic field generated by the current passing through a wire. The IULK2-38807-75 uses three different components to ensure proper protection—the magnetic bimetal, thermal bimetal, and contact system.

The magnetic bimetal detects current flow in the circuit and opens the circuit when it detects a high current flow. The thermal bimetal has a bimetal strip that contracts when it comes in contact with heat. When the temperature of the current passing through the circuit reaches a certain limit, the thermal bimetal will actuate and open the circuit. The contact system is a set of contacts that open or close the circuit depending on the current flow. The IULK2-38807-75 also has an auxiliary contact that is used to provide external signals when the circuit is opened or closed.

The IULK2-38807-75 provides reliable, low-cost protection against short circuits and overloads. It is easy to install and maintain and is an ideal choice for a variety of applications. The IULK2-38807-75 is a compact, efficient, and reliable circuit breaker that offers superior protection in even the toughest environments.
