4120-G214-J3M1-S8S0ZB-3A Circuit Protection

Circuit Breakers

The 4120-G214-J3M1-S8S0ZB-3A circuit breaker is an engineered, pre-fabricated device designed for protection against electrical circuit overload. It is used to protect electrical systems and components from short-circuits, voltage transients, ground fault currents, and other overvoltage or undervoltage conditions.

Application Field

Circuit breakers are used in both residential and industrial applications. In residential applications, they are used to protect against electric shock by interrupting electrical current when a short circuit or overload occurs. In industrial applications, they provide overload protection, ground fault protection, and short circuit protection for motors, pumps, and generators. They can also be used to protect equipment such as transformers, arc welders, and other devices that are sensitive to over-voltage and under-voltage conditions.

Working Principle

When an overload or short circuit occurs, the circuit breaker is designed to trip open, cutting off the flow of electrical current. This prevents damage to the electrical system and any connected equipment. The circuit breaker can also be manually tripped open or reset, allowing the current to be restored to the system.

The 4120-G214-J3M1-S8S0ZB-3A circuit breaker features an adjustable trip setting, allowing the user to choose the trip point for maximum protection. It is also designed with a thermal-magnetic operation, meaning it will detect both heat and magnetic forces. This ensures that it will trip sooner and more reliably in overload and short circuit situations.

Finally, the 4120-G214-J3M1-S8S0ZB-3A circuit breaker is UL-listed, so it has been tested and approved to meet the highest safety standards. This ensures that your system is being protected by a device that is reliable and that will perform as expected.
