The Schneider Electric A9C20442 is an Acti9 iCT contactor — a 2-pole, normally-open (2 NO) contactor rated for 40 A in AC-7A duty and 15 A in AC-7B duty, with a 127 V AC 60 Hz control coil.
The 40 A AC-7A rating covers resistive and lightly inductive loads like heating elements and incandescent lighting. The 15 A AC-7B rating applies to motor loads — this is the figure that governs the real-world motor-switching capability, not the higher 40 A number. For motor applications, the electrical durability is 30,000 cycles at 15 A AC-7B (60 Hz). For resistive loads, it is 100,000 cycles at 40 A AC-7A. Mechanical durability is 1,000,000 cycles. The coil is 127 V AC 60 Hz only — not a dual-frequency or DC coil. Inrush power is 34 VA; the control signal type is maintained (not pulse). The contactor is rated for 100 switching operations per day, so it is intended for on/off control, not high-speed cycling. Rated insulation voltage is 500 V AC 50/60 Hz, and the rated operational voltage is 250 V AC 60 Hz. The contactor complies with IEC/EN 61095 (household and similar electromechanical contactors) and includes tropicalisation treatment per EN 60947-4-1 and IEC 1095 for humid environments.
The housing is 36 mm wide (4 x 9 mm pitches), 85 mm high, and 68.5 mm deep. IP20 finger-safe protection on the body; IP40 in a modular enclosure. Power circuit terminals accept 6 to 25 mm² rigid or 6 to 16 mm² flexible cable; control circuit terminals accept 1.5 to 2.5 mm².
