The control coil is 127 V AC 60 Hz, maintained signal type — meaning the coil stays energised to hold the contacts closed. The 15 A AC-7B rating covers resistive loads like heaters. Electrical durability is specified per duty: 100,000 cycles at 40 A AC-7A, and 30,000 cycles at 15 A AC-7B. Mechanical durability is 1,000,000 cycles, so the contactor outlasts its electrical life in most applications — the coil or contacts will wear before the mechanism does. The 2-pole configuration uses two normally-open (NO) contacts, so it switches both line and neutral (or two phases) simultaneously. Inrush power is 34 VA — relevant for sizing the control transformer if multiple contactors pull in at once. IP20 finger-safe terminals; IP40 inside the modular enclosure. Control circuit terminals accept 1.5–2.5 mm² flexible or rigid; power circuit terminals accept up to 25 mm² rigid or 16 mm² flexible. Tightening torque: 0.8 N·m on the control side, 3.5 N·m on the power side.","metaTitle":"Schneider Electric A9C21442 Acti9 iCT Contactor, 2P, 40 A AC","metaDescription":"Schneider Electric A9C21442 Acti9 iCT contactor, 2P, 40 A AC-7A / 15 A AC-7B, 127 V AC 60 Hz coil, clip-on DIN rail mount, IP20, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Contactors"],"specifications":{"Depth":"73.5 mm","Poles":"2P","Width":"36 mm","Colour":"White","Height":"85 mm","Standards":"IEC/EN 61095","Noise level":"30 dB","9 Mm Pitches":"4","Control type":"Remote and manual control","Network type":"AC","Product name":"Acti9 iCT","Maximum power":"6 W at 250 V AC","Mounting mode":"Clip-on","Market segment":"Residential Small commercial","Tropicalisation":"2 conforming to EN 60947-4-1 2 conforming to EN 61095 2 conforming to IEC 1095","lifecycle_stage":"current","Local signalling":"Action indicator","Mounting support":"35 mm symmetrical DIN rail","Pollution degree":"2","Range Of Product":"Acti9","Device short name":"iCT","Network frequency":"60 Hz","Relative humidity":"95 % at 55 °C","Tightening torque":"Control circuit: 0.8 N.m Power circuit: 3.5 N.m","Compatibility code":"ICT","Device application":"Motor-heating-lighting","Operating altitude":"2000 m","inrush power in VA":"34 VA","Control signal type":"Maintained","Switching frequency":"100 switching operations/day","Electrical durability":"100000 cycles IEC/EN 61095 40 A 60 Hz AC-7A 30000 cycles IEC/EN 61095 15 A 60 Hz AC-7B 30000 cycles IEC/EN 61095 60 Hz AC-7C 100000 cycles EN/IEC 60947-4-1 60 Hz AC-1 30000 cycles EN/IEC 60947-4-1 60 Hz AC-3 30000 cycles EN/IEC 60947-4-1 60 Hz AC-5a 30000 cycles EN/IEC 60947-4-1 60 Hz AC-5b","Mechanical durability":"1000000 cycles","Connections - terminals":"Control circuit: tunnel type terminals2 cable(s) 1.5 mm² rigid Control circuit: tunnel type terminals1 cable(s) 1.5...2.5 mm² rigid Power circuit: tunnel type terminals1 cable(s) 6...16 mm² flexible Power circuit: tunnel type terminals1 cable(s) 6...25 mm² rigid Control circuit: tunnel type terminals2 cable(s) 1.5...2.5 mm² flexible","IP degree of protection":"IP20 conforming to IEC 60529 IP40 (modular enclosure) conforming to IEC 60529","Pole contact composition":"2 NO","Product or component type":"Contactor","[Uc] control circuit voltage":"127 V AC 60 Hz","[Ui] rated insulation voltage":"500 V AC 50/60 Hz","[Ie] rated operational current":"40 A AC-7A 15 A AC-7B","[Ue] rated operational voltage":"250 V AC 60 Hz","Hold-in power consumption in VA":"4.6 VA","Ambient air temperature for storage":"-40...70 °C","Ambient air temperature for operation":"-5...60 °C","[Uimp] rated impulse withstand voltage":"4 kV"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://www.se.com/uk/en/product/A9C21442/ict-40a-2no-127v-60hz-mo-contact/","alternativesUrl":"https://aoctrl.com/api/mcp/products/A9C21442/alternatives.json"},"ai":{"faq":[{"question":"What are the key ratings of the A9C21442?","answer":"Rated operational current: 40 A AC-7A / 15 A AC-7B.
