The tunnel-type terminals accept up to 6 mm² rigid on the power circuit and 2.5 mm² on the control circuit; tightening torque is 0.8 N.m for both, so a standard screwdriver setting works across all connections. ## Electrical ratings and durability The electrical durability varies by duty cycle: 100,000 cycles at 25 A AC-7A (resistive/motor-heating-lighting loads), 30,000 cycles at 8.5 A AC-7B (motor loads with moderate overloads), and 30,000 cycles for AC-7C and AC-3 categories. Mechanical durability is 1,000,000 cycles, so the contactor will outlast the electrical life in most applications — the contacts wear before the mechanism does. Switching frequency is rated at 100 operations per day, which is typical for a contactor in HVAC or lighting control rather than a high-speed machine cycle.","metaTitle":"Schneider Electric Acti9 iCT A9C21137 Contactor, 4P, 25 A AC","metaDescription":"Schneider Electric Acti9 iCT A9C21137 contactor. 4P, 25 A AC-7A, 24 V AC 50 Hz coil.
