Circuit breakers are electric devices designed to protect electrical systems and components when an overload occurs. The LEGZXF66-40420-10-V is an example of such a device, and this article will discuss its application field and working principle.

Introduction

A circuit breaker is an electrical device used to protect against excessive current, voltage, and short circuit faults. These devices open when the current exceeds a pre-determined limit. This reduces the risk of damage to the electrical system and components, making circuit breakers a valuable addition to any electrical installation.

Application Field of LEGZXF66-40420-10-V

The LEGZXF66-40420-10-V is a circuit breaker designed for use in small- and medium-scale industrial applications. It has a rated current of up to 10A and a rated voltage of up to 400V. The device is designed for both AC and DC electric circuits, and it is suitable for use in hazardous areas.

The LEGZXF66-40420-10-V is approved for use in a range of applications, including switchboards for domestic installations, starter panels, starter boxes, and low voltage distribution panels. It is designed to protect against short-circuit faults, load disconnection, and overloads. It is certified to the relevant standards for UL, EN, and CSA.

Working Principle of LEGZXF66-40420-10-V

The working principle of the LEGZXF66-40420-10-V is based on the principle of over-current protection. When the current in the circuit exceeds the device’s rated current of 10A, it trips and disconnects the circuit. This prevents further current, and the risk of electrical fire or other damage.

The LEGZXF66-40420-10-V is equipped with a built-in thermal trip fuse. This is designed to detect when the temperature of the circuit increases beyond a safe level. If the temperature of the circuit increases too much, the trip fuse will open and disconnect the circuit, thus preventing further damage.

The LEGZXF66-40420-10-V is also equipped with a manual operation option. This feature allows the circuit breaker to be manually tripped in the event of an emergency, such as a sudden power outage. This allows the circuit breaker to be reset and the normal operation of the circuit to be resumed.

Summary

The LEGZXF66-40420-10-V is a circuit breaker designed for use in small- and medium-scale industrial applications. It is rated at 10A and 400V and is suitable for both AC and DC circuits. It is approved for use in a wide range of switchboards and control panels, and it is certified to the relevant standards for UL, EN, and CSA.

The LEGZXF66-40420-10-V works on the principle of over-current protection, and it is equipped with a built-in thermal trip fuse that detects temperatures that are too high. It is also equipped with a manual operation option, in case of an emergency. It is a reliable and effective way to protect electrical systems and components.
