A circuit breaker, also called an overcurrent protective device, is an automated switch used to protect an electrical circuit from being in an unsafe state. It is triggered when the surge or current in the circuit exceeds its threshold. Circuit breakers come in many different forms, such as 3120-F521-P7T1-W02D-382836-0.3A.

The 3120-F521-P7T1-W02D-382836-0.3A is used in low voltage (<600V) power distribution networks. It is a molded case circuit breaker (MCCB) that provides effective protection against both overload and short circuit faults. It is widely used in commercial, industrial, and residential applications.

The 3120-F521-P7T1-W02D-382836-0.3A has a thermal-magnetic tripping system that ensures accurate and reliable protection. The thermal part of the system monitors the current of the circuit. If this current reaches a preset level, the breaker will trip, or open, thus preventing any further damage to the circuit by stopping the flow of current. The magnetic part of the system works on similar principles, allowing the breaker to trip more quickly when a short circuit or other highly fault current occurs.

The 3120-F521-P7T1-W02D-382836-0.3A is designed to be easily maintained. It has self-diagnostics and LED indicators so that any problems can be quickly detected and corrected. Rubber-type shunt trip breaker coils and undervoltage trip relays are available as accessories to enhance its versatility. Furthermore, its compact housing makes it suitable for applications with limited space.

The 3120-F521-P7T1-W02D-382836-0.3A is a reliable, solid-state circuit breaker that provides protection for circuits in commercial, industrial, and residential settings. Its thermal-magnetic tripping system accurately and reliably detects when the current in a circuit becomes too high, thus preventing further damage to the circuit. The breaker is also easy to maintain, and accessories are available to enhance its versatility.
