Circuit breakers are electrical components used to protect electrical circuits from overloads. They are often used in combination with voltage regulators or other control devices to increase the reliability or safety of an electrical circuit. The LEL1-31164-4-V is one such circuit breaker, designed specifically for electrical devices such as refrigerators, air-conditioners and electric motors. This article will discuss the application field of the LEL1-31164-4-V and its working principle.

The LEL1-31164-4-V is a two-pole, adjustable circuit breaker designed to provide overload protection for a wide range of devices. It is equipped with an adjustable trip point and has a maximum current rating of 25A. When installed, the circuit breaker monitors the current flowing through the protected circuit, and if the current exceeds the adjustable trip point, the breaker will interrupt the circuit to prevent an overload from occurring. The maximum trip point can be adjusted from 5A to 25A depending on the application, making it suitable for a wide range of applications.

The LEL1-31164-4-V is suitable for a variety of applications, including air conditioning and refrigeration systems, motors and pumps, and electric furnaces. It is also suitable for use in lighting circuits, HVAC systems and other circuits that require overload protection. The device can be used in wet or dry locations and is designed to operate at a temperature range of -30 to +100°C.

The LEL1-31164-4-V\'s working principle is based on the concept of a \'thermal magnetic trip unit\'. This device is designed to provide both an adjustable thermal trip and ballistic overload protection. When an overload or short circuit is detected in the circuit, the thermal trip unit senses this and causes the breaker to trip. This trip occurs even before the current is able to damage the protected device or cause a fire hazard. In addition, the magnetic trip element provides immediate overcurrent protection, but it does not provide protection against low-level faults.

The LEL1-31164-4-V\' is also equipped with a built-in, adjustable delay time feature. This feature allows the user to adjust the time delay of the breaker trip from a few milliseconds to several seconds, so that large inrush currents can be tolerated without tripping the circuit breaker. This feature is particularly useful for applications such as air conditioners, refrigerators, and electric motors.

In conclusion, the LEL1-31164-4-V is a two-pole adjustable circuit breaker suitable for a variety of applications. It is equipped with an adjustable thermal trip and a magnetic trip unit, as well as an adjustable delay time feature that allows the user to adjust the trip time of the breaker. Thus, the LEL1-31164-4-V provides superior protection against overloads and short circuits in a variety of electrical devices.
