At 36 mm wide (2 modular-width units) and 76 mm deep, it fits a standard DIN-rail enclosure with 70 mm installation depth.
The 2-pole configuration handles single-phase or two-phase AC circuits up to 440 V maximum in multi-phase operation. Accepts solid conductors up to 35 mm² for the incoming and outgoing terminations — sized for main feeder or sub-feed applications in a panel. The mechanical service life of 10 000 operating cycles is typical for this class of MCB — adequate for protection duty where the breaker is not cycled as a switch.
