Circuit breakers are an essential part of any electrical system. They are used to protect electrical equipment from dangerous over-currents, by automatically cutting off the power in the event of an overload. But what are the application fields and working principles of the LEGH66-1-62-10.0-AZ-91-V?

Application fields

The LEGH66-1-62-10.0-AZ-91-V is a type of circuit breaker, specifically tailored to the European market. It is a 3-pole circuit breaker, rated for 10A and operating up to 230V AC, 60V DC. This makes it suitable for most residential installations. It is compatible with DIN-type rail mounting, and comes with integrated over-temperature protection.

The LEGH66-1-62-10.0-AZ-91-V is also suitable for commercial applications, such as small-scale offices, retail units, and other businesses. It is the perfect choice for those who need a reliable and cost-effective solution for their low-voltage electrical system.

Working principle

The LEGH66-1-62-10.0-AZ-91-V circuit breaker works by using a thermal-magnetic overload protection unit. This is a system which comprises a thermal element and a magnetic element. The thermal element, usually made of a bimetallic strip, is designed to heat up when the current passing through the breaker exceeds a certain level. This causes the strip to bend, which in turn trips the breaker, shutting off the power.

The magnetic element, also known as a trip solenoid, generates a magnetic field when the current exceeds a certain level. This induces a current in the trip coil, which in turn triggers an intentional overload. This can occur in cases where the breaker experiences a short-circuit, or an excessive load. Both of these conditions can cause dangerous and damaging currents, and the magnetic element helps minimize the risk by tripping the breaker.

The LEGH66-1-62-10.0-AZ-91-V is a reliable and cost-effective solution for low-voltage electrical systems. Its thermal-magnetic overload protection unit provides reliable protection from dangerous over-currents, and its compatibility with DIN-type rail mounting makes it ideal for commercial and residential installations.
