Why Choose the Lovato 11B145SL00110 Three-Pole Power Contactor?
The Lovato 11B145SL00110 is a heavy-duty three-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 proven 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, panel builders and industrial maintenance engineers, the contactor combines robust silver alloy contacts with a powerful electromagnetic operating mechanism for dependable switching performance under demanding industrial conditions. The integrated 110–125 V AC/DC operating coil provides excellent flexibility for both AC and DC control systems.
With a 250 A AC-1 thermal current rating, a 150 A AC-3 operational current, three normally open (3NO) main contacts and a 110–125 V AC/DC control coil, the 11B145SL00110 is ideal for switching large motors, pumps, compressors and industrial power circuits. Its heavy-duty screw-mounted construction enables secure installation within industrial control panels and switchboards.
