IELHK111-31931-2-V

Circuit Breakers

IELHK111-31931-2-V is a circuit breaker, which is designed for a wide range of applications, depending on the installation, circuit, and type of current. Circuit breakers are a form of electrical protection that works to protect the electrical system and the connected equipment from damage due to current overloads or short circuits.

The IELHK111-31931-2-V circuit breaker has a short-circuit trip current rating of not more than 10kA, and is designed to protect circuits rated from 20A to 100A. The breaker can be used for AC systems in single phase, two-phase, or three-phase systems, provided the voltage and frequency conform with the ratings given. The maximum allowable continuous load for the breaker is 75%.

The working principle of the circuit breaker is based on the thermal or magnetic principle. When an overload occurs and the current exceeds the limit of the breaker, a thermal energy is generated in the circuit which is quickly released. This heat is then detected by a bimetallic strip within the breaker which is connected to the switch arm. The bimetallic strip then bends, ultimately breaking the circuit that the breaker is protecting. Likewise, in the case of a magnetic circuit breaker, when the current flowing through the breaker exceeds the rating, a magnetic field is created, which pulls a trip lever, opening the circuit.

IELHK111-31931-2-V circuit breaker can be used in a wide variety of areas, including domestic and commercial applications, such as home and office buildings, and industrial settings, such as factories and power plants. The breaker can also be employed in more hazardous locations, such as marine environments or areas subject to explosion risk. It is also suitable for use in mobile and portable applications, such as in cars or boats. The IELHK111-31931-2-V was designed to meet all applicable safety standards in both the US and Canada.

It is important to ensure the correct installation and maintenance of circuit breakers. In order to guarantee the circuit breaker’s safety and functionality, the specified overcurrent value and the current ratings of all components must meet the requirements. It is also recommended to test and inspect the circuit breakers and connected devices regularly. This will help to ensure that the circuit breaker is functioning correctly and is able to protect the electrical system and equipment connected to it.
