11B630L00220110 - 3P CONTACTOR 220/240V C/W LATCH 110VAC

Why Choose the 11B630L00220110?

Lovato B630 three‑pole contactor 11B630L00220110 delivers heavy‑duty performance with AC3 switching up to 630 A at 400 V (355 kW) and an Ith (AC1) of 800 A. It features a universal AC/DC coil rated 220…240 V and arrives already fitted with a mechanical latch (G495). The latch operates at 110…125 VAC, providing secure maintained contact where required in demanding control and motor applications.

Engineered for reliability, this contactor offers Ui 1000 V and 8 kV impulse withstand, a mechanical life of 5,000,000 cycles, and operation from −50 to +70 °C up to 3,000 m altitude (pollution degree 3). Screw mounting with 55 Nm terminal torque ensures robust connections. It complies with IEC/EN 60947‑1/‑4‑1, UL and CSA standards, and weighs 1,882 g for straightforward panel integration.
