The headline rating is 32 A in AC-3 utilisation category at ≤440 V — that is the motor-switching current, not the resistive (AC-1) rating. The coil is 440 V AC, which must match the control voltage available in the panel. Standards compliance includes EN/IEC 60947-4-1 (the contactor standard for motor starters) and EN/IEC 60947-5-1 (control circuit devices). It also carries GB/T equivalents for Chinese market acceptance. The fire-resistance rating of 850 °C per IEC 60695-2-1 supports use in equipment that must pass glow-wire tests under IEC 60335 household appliance standards. Mechanical robustness is specified: vibration at 1.5 Gn (open) and 3 Gn (closed) over 5–300 Hz, plus shock at 6 Gn (open) and 10 Gn (closed) for 11 ms. This is relevant for applications on mobile equipment or near high-vibration machinery. Mounting is on DIN rail or plate, fitting a standard panel layout. The protective treatment is TH (tropicalisation) conforming to pollution degree 3 per IEC 60068-2-30, meaning it withstands humid, cyclic temperature environments typical of non-air-conditioned industrial enclosures.
Panel Integration & Wiring Note
Dimensions are 86 mm depth, 56 mm width, and 84 mm height. The 56 mm width occupies three standard 17.5 mm DIN-rail module spaces. The spring-cage or screw terminals (confirm variant) accept conductors sized for the 32 A AC-3 rating — typically 6 mm² to 10 mm² for the power circuit. Verify the coil voltage (440 V AC) matches the control transformer tap before committing the panel wiring.
