Siemens Miniature Circuit Breaker 400 V 10kA – 5SP4392-7
MCBs from the Siemens SENTRON portfolio meet the enhanced requirements of automated buildings and industrial power supply systems, e.g. in the automotive and semiconductor industry or in data centers. Compared to residential and functional buildings, these are usually more extensive and complex in terms of both network topology and operation. Electricity and production downtimes must be deliberately prevented in these cases using coordinated device combinations if economic losses are to be avoided. Our MCBs protect wires and cables in cases of short circuit and overloads, and also enable backup protection for switching devices and also semiconductor protection. They are therefore a fundamental component in end-to-end protection concepts for industry and infrastructure.
The right combination
The main purpose of Siemens miniature circuit breakers is to permanently monitor and secure cables and wires in electrical systems. They also help protect humans against electric shocks when used in combination with RCCBs or as combined RCBO. Siemens Breaker combining the 5SY MCB with the 5SM6 arc-fault detection unit (AFDD) further expands the range of functions. An overview of all the combinations is provided below.
Strengths of the Siemens MCBs in the SENTRON portfolio – your benefits
