11B630L00220220 - 3P CONTACTOR 220/240V C/W LATCH 220VAC

Why Choose the 11B630L00220220?

The Lovato B630 three‑pole contactor delivers robust high‑current switching for demanding applications. With an IEC AC‑3 rating of 630 A at 400 V (355 kW) and an Ith of 800 A, it handles heavy loads with confidence. The 220…240 V AC/DC coil and factory‑fitted mechanical latch (G495) provide reliable hold‑in and secure state retention. Designed for screw mounting, it offers a rated insulation voltage of 1000 V and 8 kV impulse withstand.

Engineered for reliability, the B630 achieves a mechanical life of 5,000,000 cycles and operates from −50 to +70 °C, up to 3000 m altitude, pollution degree 3. Compliance with IEC/EN 60947‑1/‑4‑1 and UL/CSA standards underpins safe integration, while Lovato’s sustainability certification supports responsible procurement. The integrated mechanical latch operates at 220…240 VAC, and terminals accept a 55 Nm tightening torque for secure connections.
