IELH111-1REC4-32438-3-V

IELH111-1REC4-32438-3-V circuit breakers are widely used in residential, commercial and industrial applications. They are designed for the protection and control of electrical wiring systems and equipment against overloads, short circuits, ground faults and electrical fires. They can also be used as switches for the control and monitoring of motor loads.

The IELH111-1REC4-32438-3-V circuit breaker design features an integrated over-temperature protection system with a temperature sensing element to detect high temperatures and automatically shut off the circuit when it reaches a predetermined temperature. This is a self-resetting mechanism and will attempt to restart the circuit when it cools off again.

There are two main working principles for IELH111-1REC4-32438-3-V circuit breakers, thermal-magnetic and electronic. The thermal-magnetic principle utilizes an element of temperature sensing combined with a magnetic force to detect an overload condition or short circuit. The magneto-thermal current is used to trip the circuit when the current exceeds a predetermined level. This type of breaker is also referred to as a thermal-magnetic breaker.

The electronic principle uses an electronic sensing element and a power switch to detect an overload condition or short circuit. The electronic sensor detects the current through the circuit based on a preset threshold level and triggers a circuit breaker action when the current exceeds the preset level. This type of circuit breaker is also referred to as an electronic trip breaker.

The IELH111-1REC4-32438-3-V circuit breakers also feature a bimetallic strip which is used to detect any temperature changes in the circuit. The strip is heated up by the current running through the circuit and, once it reaches a certain temperature threshold, the strip will expand slightly and break the circuit. The bimetallic strip also offers protection against over-temperature conditions.

These circuit breakers are widely used in residential, commercial and industrial applications, as they provide protection from shock hazards, as well as preventing the damage and destruction that can be caused by electrical fires.

The IELH111-1REC4-32438-3-V circuit breaker is an efficient and reliable device, providing safe and reliable protection for the user and their electrical equipment. They are easy to install and maintain, and can be used for both residential and commercial applications.
