Siemens digital industrial circuit breaker 5SY8301-7 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 busbar due to its double chamber terminal, and 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.
