The coil is 220 V AC, so it pulls in from a standard line-voltage control circuit. The contactor carries three normally-open power poles (3P, 3 NO) and is designed for DIN-rail or plate mounting.
The AC-3 rating of 32 A at ≤440 V determines contactor fit for motor branch circuits. AC-3 covers starting and stopping induction motors. Environmental tolerance covers -20 to 70 °C at the coil (Uc), with storage from -60 to 80 °C and operation from -5 to 55 °C. Fire resistance at 850 °C and compliance with EN/IEC 60947-4-1 confirm it meets the thermal and dielectric requirements for motor starters in Europe and China (GB/T standards).
This class of contactor is the switching element inside motor starters, conveyor controls, pump panels, and compressor cabinets — anywhere a three-phase motor up to 32 A (roughly 15 kW at 400 V) needs to be started and stopped from a remote pushbutton or PLC. The DIN-rail footprint (86 mm deep, 56 mm wide, 84 mm high) fits standard 35 mm rail inside a control enclosure, and the plate-mount option gives flexibility for retrofit into existing backpanels.

It also meets EN/IEC 60335-1 Clause 30.2 and EN/IEC 60335-2-40 Annex JJ for appliance and HVAC applications. The 850 °C glow-wire test confirms fire resistance for unattended equipment. Operating altitude goes to 3000 m without derating — useful for high-altitude installations where air dielectric and cooling are reduced.
