SIRIUS circuit breakers offer reliable protection against overload and short circuit, even in case of ambient temperatures up to 70 °C (up to 60 °C without derating). The devices enable low-cost and fault-proof installation and are also optionally available with spring-loaded terminals and connection module for the circuit breaker and contactor. In addition, versions with overload relay function are available, making mechanical restarting superfluous after an overload trip. Auxiliary and signaling switches, available as accessories, communicate the current switching status as well as the tripping method.

 

Miniature circuit breakers offer reliable protection against overload and short circuit. They can be supplemented with additional components and can thus also be integrated into a control system to allow the operating status of the charging station to be detected.

 

Lightning conductors and surge arresters protect the charging infrastructure and the electric vehicle against overvoltages and surge currents. Failure of a device can be reported via remote signaling.

 

Residual current circuit breakers are used for personnel and property protection, protection against fire and additional protection in the event of direct contact. An universal current-sensitive residual current circuit breaker Type B (SIQUENCE) is recommended for the charging station. In addition to AC residual currents and pulsing DC residual currents, it also detects smooth DC residual currents and thus secures the desired protection function in case of all residual current types.
