The control coil is rated for 24 VAC at 50 Hz, with a hold-in power consumption of 3.8 VA and an inrush of 15 VA. That's a steady-state draw of about 0.16 A on the control transformer, so factor that into your control circuit sizing if you're running several of these off one supply. Rated operational current is 25 A in AC-7a duty (resistive loads like heating elements) and 8.5 A in AC-7b (motor loads like small pumps or fans). Electrical durability is 100,000 cycles at 25 A AC-7a, and 30,000 cycles at 8.5 A AC-7b, so for frequent motor starting you'll want to check that cycle count against your application duty. ## Where you'd use it This contactor is built for commercial and light industrial panel applications — think HVAC contactors, lighting contactor banks in a retail space, or motor starters for small conveyors and fans. The 2-pole configuration with two NC auxiliary contacts (pole contact composition 2 NC) means it's ready for a maintained control signal, and the local action indicator gives a visual confirmation of state without needing to meter the load side. Pollution degree 2 (non-conductive dust, occasional condensation) is typical for a clean, dry indoor enclosure. The 18 mm width means it takes up one standard modular space, so you can pack several into a row. Terminal connections are tunnel-type: power circuit accepts 1 to 4 mm² flexible or 1.5 to 6 mm² rigid; control circuit accepts 1.5 to 2.5 mm² rigid or flexible, with up to two conductors per terminal. Tightening torque is 0.8 N·m for both power and control circuits — use a torque screwdriver to avoid crushing the wire or loosening over time. Designed and tested to IEC/EN 61095 (household and similar electromechanical contactors) and referenced against EN/IEC 60947-4-1 (low-voltage switchgear for motor starting). The tropicalisation treatment (2 levels per EN 60947-4-1 and IEC 1095) means it's treated against humidity and fungal growth — useful if the panel ends up in a warm, damp environment.","metaTitle":"Schneider Electric A9C21136 Acti9 iCT Contactor, 2P, 25 A AC","metaDescription":"Schneider Electric A9C21136 Acti9 iCT contactor, 2-pole, rated 25 A AC-7a / 8.5 A AC-7b at 250 VAC, 24 VAC 50 Hz coil.
