Circuit Breakers

The 3120-F321-P7T1-W02K-X3120-M2P7M-120V-20A is a circuit breaker designed to protect an electrical circuit from an overload of voltage or current. It will detect an overload in the circuit and immediately disconnect it in order to protect the circuit and components. It can also be used for general switching purposes.

Application Field

Circuit breakers are commonly used in residential, commercial, and industrial settings as a protective device for wires, switches, and other electrical components, such as fuses and surge protectors. In residential settings, they are often found in HVAC systems, home entertainment systems, and garages. In commercial and industrial settings they are used to protect electrical equipment, such as motors and transformers.

Working Principle

The 3120-F321-P7T1-W02K-X3120-M2P7M-120V-20A circuit breaker utilizes a current sensing feature that calculates the rate of the current flow. If the rate of current flow is detected to be too high, the circuit breaker will trip and cut off the power to the circuit. This functionality is achieved by a bimetallic strip located in the circuit breaker. When the bimetallic strip is overloaded, it bends and triggers a switch that disconnects and cuts off the power to the circuit.

In addition, the 3120-F321-P7T1-W02K-X3120-M2P7M-120V-20A circuit breaker is designed with a reset function. When tripped, the breaker must be manually reset by pushing a button or turning a dial. This prevents the circuit breaker from being inadvertently reset and allows for safety checks to be done before power is restored.

The 3120-F321-P7T1-W02K-X3120-M2P7M-120V-20A circuit breaker is a reliable and effective way to protect electrical circuits from an overload of voltage or current. It is designed for easy installation and use, and when correctly used, it can provide much needed safety for any electrical system.
