Its 40 A rated operational current at ≤440 V AC (AC-1) defines the continuous resistive load it can carry — think heater banks, lighting, or other non-inductive circuits where inrush is minimal. The 4 NO pole configuration means all four contacts are normally open, so the contactor bridges the load when the coil pulls in. The control circuit is a 220 V AC 50 Hz wide-range coil, with operational limits of 0.7 to 1.25 Uc and drop-out between 0.3 and 0.6 Uc across -5 to 55 °C. Inrush power at pickup is 95 VA at 50 Hz, cos φ 0.75, so factor that into transformer sizing if the panel runs multiple contactors on one control supply.
Depth is 93 mm, height 84 mm — check enclosure depth clearance, especially in shallow gland-plate areas. IP20 finger-safe protection means it belongs inside a locked panel, not exposed to washdown. Power circuit terminals accept 1 to 6 mm² flexible with cable end (or 1.5 to 6 mm² solid), torqued to 1.5 N·m. Control circuit terminals take 1 to 4 mm² flexible without cable end, torqued to 1.2 N·m. The screw-clamp design is standard for panel builders — no special tooling needed.
Designed and certified to EN/IEC 60947-1, 60947-4-1, and 60947-5-1, plus the Chinese GB/T equivalents. Protective treatment TH per IEC 60068-2-30 means it withstands damp heat, so it can live in non-conditioned plant environments.
Sourcing reality
No last-time-buy or phase-out notice applies. For BOM-line commitment, the 40 A AC-1 rating and 4 NO pole count are the fit-determining specs — confirm your load is resistive and within that current envelope.
