A circuit breaker is an electrical protection device designed to automatically interrupt the flow of current in a circuit when it detects abnormal conditions, such as overload or short circuit. It acts as an "automatic switch," protecting circuits and connected equipment from damage caused by excessive current.

 

How it works

Inside a circuit breaker, there is a mechanism that moves to open the contacts when the current exceeds a certain limit. This limit can be adjusted so that the circuit breaker operates at different current levels, depending on the application. Interrupting the current prevents cables, devices, and other components from being damaged.

 

Applications

Circuit breakers are essential in residential, commercial, and industrial systems, where they protect lighting circuits, motors, transformers, control panels, and transmission lines. In industrial installations, they are often connected to control systems for remote monitoring, increasing the reliability and safety of the electrical system.

 

Compact Home SH200T miniature circuit breakers are current limiting devices. They have two different tripping mechanisms: the delayed thermal tripping mechanism for overload protection and the electromechanical tripping mechanism for short-circuit protection. They are available in different characteristics (B, C), configurations (1P, 1P+N, 2P, 3P, 3P+N, 4P), breaking capacities (up to 3 kA at 230/400 V AC), and rated currents (up to 40 A). All MCBs in the SH200T product range comply with IEC/EN 60898-1, allowing their use in residential applications.
