Why Choose the Lovato 11B1454SL0048 Four-Pole Power Contactor?

The Lovato 11B1454SL0048 is a heavy-duty four-pole industrial power contactor designed for reliable switching of high-current electrical loads in motor control, power distribution and industrial automation systems. As part of the robust Lovato B145 contactor series, this version is predisposed for installation of the optional G495 mechanical latch, allowing future conversion to mechanically latched operation when required.

Designed for OEM machine builders, switchboard manufacturers and industrial maintenance engineers, the contactor combines durable silver alloy contacts with a high-performance electromagnetic operating mechanism to deliver dependable switching performance in demanding industrial environments. The integrated 48 V AC/DC operating coil provides compatibility with both AC and DC control circuits.

With a 250 A AC-1 thermal current rating, a 150 A AC-3 operational current, four normally open (4NO) main contacts and a 48 V AC/DC control coil, the 11B1454SL0048 is ideal for switching large motors, heating systems and industrial power circuits. Its heavy-duty screw-mounted construction enables secure installation within electrical control panels and switchboards.
