It switches motor, heating, and lighting loads on 250 V AC 60 Hz networks, with a rated operational current of 40 A in AC-7A duty (general motor loads) and 15 A in AC-7B duty (resistive loads). 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.
