It carries a 12 A rating in AC-3 and AC-3e utilisation categories at ≤440 V, which means it is sized for switching three-phase induction motors up to that current — the AC-3 category specifically covers starting and stopping squirrel-cage motors under full load. The 110 V AC coil operates on 50/60 Hz supplies, a common control voltage in industrial panels worldwide. This timing is critical when the contactor is used in safety circuits or reversing starters where a break-before-make sequence must be enforced to prevent phase-to-phase shorts.
Standards, approvals, and environmental tolerance
Protective treatment TH conforming to IEC 60068-2-30 means it is tested for damp heat, cyclic — suitable for non-condensing humid environments typical of many industrial sites.
IP2X finger protection per IEC 60529 covers the front of the device — adequate for enclosed panels where accidental contact is prevented by the enclosure door. Mechanical robustness is specified for vibration: 1.5 Gn (5–300 Hz) with contacts open, 3 Gn with contacts closed. Shock resistance is 7 Gn for 11 ms open, 10 Gn for 11 ms closed. These figures confirm the contactor holds its state under moderate machine vibration — relevant when mounted on a panel attached to a running conveyor or compressor skid.
