The headline rating is 40 A in AC-7A duty (inductive loads like motors with low inrush) and 15 A in AC-7B (resistive loads like heating), both at 250 V AC 60 Hz. The coil is rated 220-240 V AC at 60 Hz, drawing 34 VA inrush and 6 W holding. It requires a maintained control signal — no pulse or momentary latching — so the control circuit must hold the coil voltage continuously for the contactor to stay closed. The control circuit terminals accept up to 2.5 mm² flexible cable, torqued to 0.8 N.m; the power circuit terminals take up to 25 mm² rigid, torqued to 3.5 N.m.
The 36 mm width (4 x 9 mm pitches) and 85 mm height fit alongside other Acti9 modular devices. IP20 finger protection on the body; IP40 inside a modular enclosure. Pollution degree 2 (non-conductive dust, occasional condensation) covers most clean indoor panel environments.
Durability and switching duty
Electrical durability varies by duty: 100,000 cycles at 40 A AC-7A, 30,000 cycles at 15 A AC-7B, and 30,000 cycles for AC-3 (cage motor starting) and AC-5a/AC-5b (discharge lamp switching). Mechanical durability is 1,000,000 cycles. The rated switching frequency is 100 operations per day — this is not a high-speed cycling contactor; it's sized for daily on/off control of a fixed load like a fan or heater bank.
