RCBO, 10 kA, 4P, type B+, selective, 300 mA, D char., In: 100 A, Un AC
RCBO, 10 kA, 4P, type B+, selective, 300 mA, D char., In: 100 A, Un AC: 400 V RCBOs for combined short-circuit protection and anti-contact protection. An important element of the SENTRON protective devices for electrical installations, the patented RCBOs from Siemens allow combined personnel, fire and cable protection in just one device. In addition to detecting the fault currents, they also provide reliable protection against short-circuits and overloads thanks to the integrated overcurrent protective device. As a combination of residual current and miniature circuit breaker, the Siemens RCBOs are primarily characterized by: https://www.siemens.com/global/en/home/products/energy/low-voltage/components/sentron-protection-devices/residual-current-protective-devices.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.
