The AC-3 rating of 12 A at ≤440 V governs motor switching; for resistive loads (AC-1) the thermal capacity is higher.
The contactor carries a single normally-open auxiliary contact (1 NO) for status feedback or interlocking. The 690 V AC rated operational voltage on the power circuit means the main poles can switch motor loads on a 400 V or 480 V line without derating the insulation.
The V-0 flammability rating (UL 94) and NF F 16-101 compliance cover rail and industrial fire-safety requirements.
