4120-G214-J1M1-B2S0ZN-0.5A

Circuit Breakers are an essential protective mechanism for electrical systems. They are designed to sense dangerous levels of current, both AC and DC, and safely shut off power if the levels exceed the rated capacity of the circuit. 4120-G214-J1M1-B2S0ZN-0.5A is a type of circuit breaker, and in this article, we explore its application field and working principle.

Application Field

4120-G214-J1M1-B2S0ZN-0.5A Circuit Breakers are designed for use in 20A - 200A 277/480V, AC3 applications. They are used for overload, short-circuit, and ground-fault protection in conjunction with motor control centers or appliance control. Typical applications include industrial NEMA 1-12, 1-13 and domestic NEMA 1-15, 1-16 services. In addition, 4120-G214-J1M1-B2S0ZN-0.5A can be used for equipment control applications, such as HVAC, and as auxiliary control switches.

Working Principle

The 4120-G214-J1M1-B2S0ZN-0.5A Circuit Breakers feature thermal-magnetic trip elements. The trip elements consist of a series of lines that carry current corresponding to the current in the circuit breaker. When the current exceeds the rated capacity, the trip element current induces a magnetic force on the trip element itself, allowing for safepower shut off. The thermoelement inside the circuit breaker senses excess current as heat, and if the current is overly high, this heat triggers the shut off. This adds an additional protection layer beyond the magnetic tripping.

The 4120-G214-J1M1-B2S0ZN-0.5A Circuit Breakers also feature a manual reset button. This allows for resetting the circuit breaker in the event of a trip, restoring power to the circuit breaker and continuing operation as normal. The manual reset button also helps to further isolate the circuit breaker from dangerous levels of current, preventing it from tripping due to a minor overload.

In addition, 4120-G214-J1M1-B2S0ZN-0.5A circuit breaker also provides a disconnect switch, which isolates the circuit breaker and prevents the current flowing through it, and a short-circuit indicator light, which indicates the status of the short-circuit in the circuit.

Conclusion

4120-G214-J1M1-B2S0ZN-0.5A Circuit Breakers are designed for use in a variety of applications, with a wide range of ratings covering 20A - 200A 277/480V, AC3. They feature thermal-magnetic trip elements, a reset button, a disconnect switch, and a short-circuit indicator light. These features ensure the safety of electrical systems, re-establish power after an overload or short-circuit, and isolate the circuit breaker from any further overcurrent.
