(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) Special version with “ß = 1” or “ß = 1, RI” curves for the Belgian market: please ask ABB for availability and delivery times
