Siemens digital industrial circuit breaker 5SY8310-7 is a miniature circuit breaker designed for safe short-circuit and overload protection for residential buildings, functional buildings, and special industrial applications. It features tool-free mounting and dismounting with the aid of a double slide. The device allows for any combination of conductors and busbars due to its double-chamber terminal. Simple wiring of the feeder is facilitated by the busbar located at the rear.

5SY miniature circuit breakers are available in 1-, 2-, 3-, 4-, as well as 1+N- and 3+N-pole versions. All accessories can be used uniformly for all 5SY miniature circuit breakers, ensuring safety with SENTRON's protective devices.
