11B630SL00220 - 3P CONTACTOR 220/240V W/O LATCH

Why Choose the 11B630SL00220?

Designed for demanding motor control and power switching, the Lovato B630 three-pole contactor delivers AC-3 performance of 630 A/355 kW at 400 V with an AC/DC coil rated 220-240 V. With a rated insulation voltage Ui of 1000 V and 8 kV impulse withstand, it offers robust electrical endurance. Screw mounting and predisposition for mechanical latch G495 simplify panel integration and enable reliable maintained-contact operation when required.

Built for longevity and harsh environments, the B630 achieves 5,000,000 mechanical cycles and operates from -50 to +70 °C, with storage from -60 to +80 °C. Suitable up to 3000 m altitude with pollution degree 3, it maintains performance in varied installations. Terminal tightening torque of 55 Nm, 1,875 g weight, and compliance with IEC/EN 60947 and UL/CSA standards complete a reliable, high-capacity contactor.
