Its headline AC-3 rating is 12 A at ≤440 V — that's the current it can switch a standard squirrel-cage induction motor on and off under full load, which is the rating that governs real motor-starting applications, not the higher AC-1 resistive rating. The coil is 240 V AC, so it pulls in cleanly on a standard single-phase control transformer.
Height is 74 mm. For a panel-builder, the DIN-rail clip saves backplate drilling, but if vibration is a concern in the cabinet, the screw-on plate mount is the better call.
What the standards tell you
Certified to EN/IEC 60947-4-1 (the contactor standard for motor starters) and EN/IEC 60947-5-1 (control circuit devices). Also carries GB/T equivalents for the Chinese market. The 850 °C glow-wire test per IEC 60695-2-1 means the plastic housing won't propagate a flame under fault — relevant for panel builders who need to pass a fire-risk assessment.
Installation constraints at a glance
Operates at -5 to 55 °C ambient with the coil at rated voltage. Storage range is wider at -60 to 80 °C. The 1.5 ms non-overlap time between NC and NO contacts is the mechanical guarantee that break-before-make holds — critical for interlocking reversing starters where both contactors must never close simultaneously.
