LEGHS66-35402-30-V Circuit Protection

Circuit breakers are used to protect electrical circuits from damage caused by overload or short circuit. They are devices designed to break the connection between two electrical systems, thus stopping the flow of current. LEGHS66-35402-30-V is a commonly used type of circuit breaker. This article will discuss the application field and working principle of this type of circuit breaker.

LEGHS66-35402-30-V circuit breaker is a three-pole special compact circuit breaker. It is suitable for both AC 50Hz/60Hz with a rated voltage up to 400V, and a rated current up to 10A. It is mainly used in TN systems for overload and short circuit protection, as well as protection for small and medium-sized motors and lighting systems. It is also an ideal device for switching and controlling of power circuits.

The working principle of LEGHS66-35402-30-V circuit breaker is based on a bimetallic component that acts as a temperature sensor. When the current passes through the bimetallic component, it causes the two metal strips to bend. If the current exceeds normal limits, the metal strips will bend to a point where a lever connected to the component will trip, breaking the circuit. This mechanism allows the circuit breaker to quickly disconnect an overloaded circuit, thus preventing damage to the components.

The LEGHS66-35402-30-V circuit breaker also features a number of additional safety features. It is equipped with a thermal overload protection device that will trip the breaker if the current exceeds the maximum allowable limit. The circuit breaker also has a mechanical interlock system which disables the breaker if the door of its enclosure is opened. This ensures that no accidental contact with the live parts can occur.

LEGHS66-35402-30-V circuit breaker is an important safety device for electrical systems. It is designed to protect against both overloads and short circuits, thus preventing damage to wiring or equipment. Thanks to its thermal overload protection device and mechanical interlock system, it provides an extra layer of security, ensuring that the system remains safe and efficient.
