FI circuit breaker block, residual current circuit breaker block independent of mains voltage in selective design [S] according to EN61009-1 Appendix G for combination with circuit breakers of the corresponding series and number of poles. The FI circuit breaker block is mounted on the right-hand side of the circuit breaker and 2 additional devices can be mounted on the left-hand side. After mechanical assembly, the devices are permanently connected to one another. The switching lever can be sealed in the switched-on and off state or can be locked with a lever lock (order accessories separately) for a padlock. With fold-down label plate on the circuit breaker. Connection (max.): flexible 50 mm², rigid 70 mm² with built-in box terminals. With the included conversion kit, the box terminals can be exchanged for a connection for ring cable lugs (hole for M6 screws / width max. 17 mm). The connection screws can be provided with a sealable cover (accessory to be ordered separately). The rated switching capacity depends on the installed circuit breaker.
