11B6300048 - 3P CONTACTOR B630.00 48V

Why Choose the 11B6300048?

Designed for demanding three-phase control, the Lovato B630 three-pole contactor (SKU 11B6300048) combines a 48 VAC/DC coil with rugged switching performance. Rated 630 A AC-3 at 400 V (355 kW) and 800 A Ith (AC-1), it delivers reliable duty for heavy loads. Certified to IEC/EN 60947-1 and -4-1, plus UL and CSA equivalents, it provides assured compliance in industrial panels.

Engineered for longevity, it offers 5,000,000 mechanical cycles and operates from -50 to 70 °C (storage -60 to 80 °C). With Ui 1000 V and Uimp 8 kV, plus Pollution Degree 3, it withstands harsh conditions up to 3000 m altitude. Screw mounting and 55 Nm terminal torque support secure installation, while its 1840 g build reflects robust construction.
