The 110 VAC at 50/60 Hz coil pulls in cleanly across both line frequencies, so it lands in panels fed from either 50 Hz or 60 Hz mains without a coil swap. Rated 6 A in AC-3 duty (inductive motor loads) and 15 A in AC-1 (resistive loads), it covers small pumps, fans, conveyors, and heater banks up to those currents.
The slip-on terminals accept push-on connectors for the coil and power wiring — speeds up panel wiring and replacement compared to screw-clamp terminations. The built-in 1NO auxiliary contact gives a feedback signal for PLC input or a holding-circuit interlock without bolting on a separate aux block.
Motor horsepower coverage: 0.5 HP at 115 VAC single-phase, 1.5 HP at 230 VAC single-phase, 1.5 HP at 200/230 VAC three-phase, and 3 HP at 460/575 VAC three-phase. That 3 HP at 575 VAC rating is the one to check if the plant runs 575 V distribution — many contactors in this frame size top out at 460 V. The IEC construction standard means it follows IEC 60947-4-1 for contactors and motor starters, so it coordinates with IEC-rated overload relays and short-circuit protection devices.
