FI circuit breaker block, mains voltage-independent residual current circuit breaker block in accordance with 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 when switched on and off or locked with a lever lock (order accessories separately) for a padlock. With fold-down label 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 (order accessories separately). The rated switching capacity depends on the installed circuit breaker. The rated residual current is adjustable. The tripping time is adjustable. The setting potentiometers are located under a sealable, transparent cover.
