Circuit Breakers

IULHK111-1-42-20.0-B-01 application field and working principle

Circuit breakers are used to protect electrical circuits from overload and short circuit. The IULHK111-1-42-20.0-B-01 is a type of circuit breaker, specifically designed for high-selectivity coordination with ground fault equipment. It has a range of uses in industries such as power and construction, as well as in household applications.

The IULHK111-1-42-20.0-B-01 circuit breaker works by using an electromagnet, a movable core and a set of contacts to trip the circuit when dangerous amounts of current, voltage or temperature are sensed. When the current exceeds the pre-set limit, the electromagnet will move the core and open the contacts, interrupting the current flow and preventing any further damage.

The IULHK111-1-42-20.0-B-01 is designed to operate with high selectivity, meaning it is able to detect ground faults and interrupt the circuit without tripping other circuit breakers connected to it. It can also be used to protect against overloads, and can reset itself after an overload if it is able to cool off. This makes it well suited to applications where load can vary, such as construction or power.

The IULHK111-1-42-20.0-B-01 circuit breaker is also designed to provide maximum safety and reliability. It can be tested in accordance with IEC60947-2 standards and comes with a two year warranty. The high selectivity of the IULHK111-1-42-20.0-B-01 also ensures that it is able to protect circuits from damage, whilst still being able to provide a high level of protection. This makes the IULHK111-1-42-20.0-B-01 circuit breaker suitable for use in a wide range of applications.

In summary, the IULHK111-1-42-20.0-B-01 circuit breaker is a highly reliable, high-selectivity circuit breaker that is suitable for a wide range of applications in industries such as power and construction, as well as in household applications. It is designed to provide maximum safety and reliability, and is able to detect ground faults and interrupt the circuit without tripping other circuit breakers connected to it. In addition, it can be tested in accordance with IEC60947-2 standards and comes with a two year warranty.
