Detail

Miniature circuit breaker 400 V 10kA, 3-pole, C, 45 A, D=70 mm The miniature circuit breaker is the fuse for short-circuit protection. The miniature circuit breakers from Siemens, as an important component of the SENTRON protective components for electronic installations, provide effective protection for personnel and plants by reliably shutting down in the event of an overload or short-circuit. User-friendly mounting and connection technology, standardized additional components and an integrated design – these are the characteristics of the device family. Whether for infrastructure or for industrial requirements, Siemens provides miniature circuit breakers for all applications and every application area. The Siemens miniature circuit breakers are characterized primarily by: 1. Effective personnel, investment and plant protection against overload and short-circuits. 2. A wide variety of standardized accessories, easy to install and replaceable at any time. 3. Reliable safety during installation due to standard reach-around and touch protection. 4. Toolless removal from the standard mounting rail or from the busbar assembly simply by operating a manual slide. 5. Clearly visible switch position indicator. 6. The data matrix code on the front of the device provides quick and easy access to information on all aspects of miniature circuit breakers. 7. Protection as per the standards with worldwide approvals. https://www.siemens.com/global/en/home/products/energy/low-voltage/components/sentron-protection-devices/miniature-circuit-breakers.html. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution systems as well as switches and sockets for safe and efficient electrical infrastructure in buildings and industry.
