Circuit Breakers

A Circuit Breaker (CB) is an essential device that can cut off electrical power in a system in order to protect it against overload, short circuit, and other faults. IULHK111-1REC4-41-2.50-A-01 is a type of circuit breaker, which has many applications and a unique working principle.

Application Field

IULHK111-1REC4-41-2.50-A-01 is designed for highly reliable and low voltage switchgear systems. It is suitable for residential, commercial and industrial settings, such as factories, shopping malls, hotels, and office buildings. It can be used to protect against overload of high-current appliances, hazardous connecting cables, and illegal tapping. It also offers protection from electrical shock, fire, and other safety issues.

In addition, IULHK111-1REC4-41-2.50-A-01 is also suitable for medium voltage environment. It can be used in industrial automation applications, such as power supply switchgear systems in motor control centers, solar energy systems, and emergency lighting systems.

Working Principle

IULHK111-1REC4-41-2.50-A-01 is an automatically-operated device which functions when the current exceeds the preset value. It uses a special thermal and magnetic contact structure. The contacts are opened and closed by a predetermined motion, responding to currents greater than a certain predefined value. This circuit breaker has an instantaneous release mechanism, which is designed to quickly actuate when an excessive current is detected.

When the current reaches the rated value, the contact elements will be heated by Joule\'s law, due to the strong electric current. As the temperature rises, the metal oxide moving parts will expand, pushing the contact head off the circuit. The breaker is then mechanically locked in the open position and the electric current will be interrupted.

IULHK111-1REC4-41-2.50-A-01 also has a built-in overvoltage protection which will actuate when the electric voltage exceeds the preset value. This feature is important for safety’s sake, as higher voltages can be extremely dangerous.

IULHK111-1REC4-41-2.50-A-01 is a reliable and safe circuit breaker. It ensures that electrical systems are protected from any potential damage or safety hazards due to high current, short circuits, and overvoltage, as well as provide long-term service life in high voltage environment.
