Electromagnetic compatibility
(1) For circuit-breakers with PR 521 device and 3 current sensors, increase the weight indicated by 20 kg
(2) Rated current of the current sensors (the PR521 device and the current sensors are optional)
(3) DK type phase current sensors on board the circuit-breaker and DK type toroidal CT not on board (the PR521/DK device and the DK sensors are optional)
(4) VD4/UniMix-F for P1/F Unit (fixed circuit-breaker without wheels and cabled to terminal box)
(5) VD4/UniMix-R for P1/F Unit (fixed circuit-breaker with wheels and power cord with plug)
