Circuit breakers are a widely used form of electrical protection from damaging electrical currents, overvoltage, and short circuits. This article will discuss the IULK1-38559-20 circuit breaker, discussing its application field and working principle.

Introduction

The IULK1-38559-20 circuit breaker is a highly popular choice for various types of electrical systems. It is a type of miniature circuit breaker (MCB) which is designed to protect electronic equipment that is sensitive to overcurrent or short circuits. It has a variety of features including thermal-magnetic tripping, LED indication, surge suppression, and adjustable trip time delay.

Application Field of the IULK1-38559-20

The IULK1-38559-20 circuit breaker is suitable for use in a range of different electrical systems. It is often used in residential applications such as homes and offices, as well as industrial applications such as factories and power plants. It is also suitable for use in public buildings and the healthcare industry, where safety and reliability are critical performance characteristics.

Working Principle

The IULK1-38559-20 circuit breaker is a thermal-magnetic tripping device, meaning it is both thermally and magnetically sensitive. When an overload or short circuit occurs, both the thermal and magnetic elements of the breaker are triggered, resulting in a rapid tripping response.

When an overload occurs, the heat generated by the current flow causes a chemical reaction within the breaker, resulting in the expanding of bimetallic strips. This causes the breaker to trip, cutting off the electrical supply and preventing the circuit from being damaged by an overload.

The magnetic element of the breaker is triggered by a rapid rise in current. This induces a magnetic field which causes a plunger to move and trip the breaker. This process is significantly faster than the thermal response time, providing increased protection against short circuits and damaging electrical currents.

Summary

The IULK1-38559-20 circuit breaker is an excellent choice for a range of uses, from residential applications to industrial or healthcare applications. It is a thermally and magnetically sensitive breaker, responding quickly and reliably to overcurrents and short circuits. With its wide range of features, it is a trusted and widely used breaker for commercial, industrial, and residential applications.
