Description

Circuit breaker 230/400V T=70mm 25kA according to EN 60947-2, 1P, C20 The circuit breaker is the circuit breaker for short-circuit protection. The circuit breakers from Siemens, an important component of SENTRON protection components for electrical installations, provide effective protection for people and systems by safely switching off in case of overload and short circuit. Convenient mounting and connection technology, uniform additional components and a uniform design - these are the characteristics of the device family. Whether for infrastructure or for industrial requirements, Siemens offers circuit breakers for all applications and every application area. The Siemens circuit breakers are distinguished above all by: 1. Effective protection for people, investments and systems from overload and short circuit. 2. Uniform accessories in a wide variety are easy to mount and can be replaced at any time. 3. Reliable installation safety thanks to the standard grip and protection against accidental contact. 4. Tool-free release from the DIN rail or from the bus rail system using convenient slide-hand actuation. 5. Clearly visible switching position display 6. Datamatrix-Code at the front of the device offers all information about circuit breakers quickly and easily. 7. Standard-compliant protection with worldwide approvals. For the secure, efficient electrical infrastructure in buildings and industry, Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution systems as well as switches and sockets.
