It carries three normally open power poles and one normally open auxiliary contact. The 110 V DC coil means it's a fit for control circuits running on DC supplies, common in industrial panels with battery-backed or DC-distributed control. IP20 finger-safe protection (per VDE 0106) suits it for enclosed panel mounting where personnel won't contact live parts during normal operation. Flame retardance meets V1 per UL 94 and NF F 16-101/102, which matters for rail and industrial compliance.
For a 3-phase motor, 12 A AC-3 typically corresponds to a motor of about 5.5 kW at 400 V. The AC-4 rating (inching/plugging) will be lower; if your application involves frequent reversing under load, derate accordingly. The 110 V DC coil draws a holding current that's lower than the pick-up surge; verify your DC supply can deliver the inrush without droop.
