11B6301000400220 - 4P CONTACTOR B630/1000.4 220/ 240VAC

Why Choose the 11B6301000400220?

Lovato’s four-pole contactor B6301000 delivers dependable high‑current switching for demanding installations. Rated Ith (AC1) at 1000 A and AC‑3 at 400 V to 630 A / 355 kW, it features a universal 220…240 VAC/DC coil for flexible control schemes. With 1000 V rated insulation (Ui) and 8 kV impulse withstand (Uimp), it offers robust dielectric performance for industrial power distribution and motor control applications.

Built for reliability, this screw‑mounted contactor provides 5,000,000 mechanical cycles and secure connections with 55 Nm terminal tightening torque. It operates from −50 to +70 °C, stores from −60 to +80 °C, and is suitable up to 3000 m altitude, pollution degree 3. Conforms to IEC/EN 60947‑1 and 60947‑4‑1, plus UL and CSA equivalents, with a 2566 g build for durable panel integration.
