Mechanical durability is rated at 1,000,000 cycles. The switching frequency is limited to 100 operations per day — this is not a high-speed cycling contactor; it is sized for occasional on/off control in a panel. The housing is white, IP20 rated — suitable for clean, dry enclosure environments. Control circuit tunnel terminals accept 1.5 to 2.5 mm² flexible cable; power circuit terminals accept up to 25 mm² rigid or 16 mm² flexible. Tightening torque is 0.8 N·m on the control side and 3.5 N·m on the power side. Rated for operation at altitudes up to 2000 m, in ambient temperatures from -5 °C to 60 °C, and at 95% relative humidity at 55 °C. Pollution degree 2 (non-conductive pollution only). Tropicalisation treatment is applied per EN 60947-4-1 and IEC 1095. Approvals include IEC/EN 61095 (the standard for household and similar electromechanical contactors) and EN/IEC 60947-4-1 (for industrial contactors and motor-starters). This dual-standard coverage means the part is accepted in both commercial and light-industrial installations across Europe and other IEC-adopting regions.","metaTitle":"Schneider Electric A9C21147 Acti9 iCT 4P Contactor, 40 A AC-","metaDescription":"Schneider Electric A9C21147 Acti9 iCT 4-pole contactor.
