Circuit breakers are among the most important safety devices used in home and industrial electrical systems. They are designed to detect a sudden surge in current or voltage, and respond by breaking the circuit and preventing further damage. 1CU20L circuit breakers are among the most advanced on the market and offer a number of advantages over traditional breakers.

The 1CU20L circuit breaker is a double-pole, self-grounding, thermal-magnetic, manually operable circuit breaker with overload and short circuit protection. It is designed to provide overcurrent protection for branch circuits, motor circuits, and branch circuits in installation areas accessible to non-qualified personnel. It has an adjustable current setting that allows it to be adjusted to the exact current required by the system it is protecting.

The working principle of the 1CU20L circuit breaker is based on two types of protection: thermal protection and magnetic protection. Thermal protection is provided by a bimetallic element that reacts to changes in temperature caused by increases in current. As the current increases, the bimetallic element bends, activating the trip mechanism.

The magnetic protection is provided by an electromagnet mounted on the operating mechanism. When the operating current reaches a pre-set level, the magnetic field produced by the electromagnet causes the movable contact to move away from the fixed contact, opening the circuit and breaking current flow.

The 1CU20L circuit breaker is a popular choice for many applications due to its high breaking capacity, flexibility and ease of use. It is suitable for use in many areas including residential, commercial, industrial and marine. It is also suitable for use in high humidity and extreme weather conditions.

The 1CU20L circuit breaker is an excellent choice for applications requiring a combination of high breaking capacity, accuracy and flexibility. With its adjustable current setting and automatic thermal and magnetic protection features, it ensures the highest levels of safety and operational performance in any environment.
