The 125 V DC control coil pulls in at 0.85 to 1.1 times nominal and drops out between 0.2 and 0.35 times nominal at 55 °C, so a saggy 125 V DC bus won't cause nuisance dropouts until it falls below about 25 V. Rated operational voltage goes up to 460 V DC, and the rated insulation voltage is 1000 V per IEC 60947-4-1 (1500 V per VDE 0110 group C).
Above that, the operating range tops out at 55 °C, so you'll need to account for panel internal temperature rise. The rated short-time withstand current (Icw) is 10,000 A for 10 seconds, 7,500 A for 30 seconds, and 5,500 A for 1 minute — these numbers govern coordination with upstream protective devices: a 2,000 A gG fuse at ≤440 V is the recommended backup. Power dissipation is 200 W per pole in AC-1 duty, totalling 600 W across the three poles at full load — that's the heat you have to vent from the enclosure. The coil itself dissipates 10 W holding in, with an inrush of 2,100 W at 20 °C during pickup. Average impedance per pole is 0.1 mOhm at 2,100 A, 50 Hz. Operating time is 50 to 60 ms closing and 45 to 60 ms opening — fast enough for most resistive load switching but not for synchronous transfer or fast bus-tie applications. Maximum operating rate is 600 cycles per hour at 55 °C.
This is a plate-mount contactor — no DIN rail clip. The footprint is 438 mm wide by 332 mm high by 238.6 mm deep, so it needs a backplate or sub-panel, not a standard 35 mm rail. Power connections are bolted bars accepting up to four cables or busbars 100 x 5 mm cross-section. Control circuit terminals are screw-clamp, accepting 1 to 4 mm² flexible or solid wire (with or without ferrules). Tightening torque is 1.2 N·m on the control circuit and 58 N·m on the power circuit — that's substantial; use a torque wrench on the power lugs.
