11B145L00220220 – 3P CONTACTOR 220/240V C/W LATCH 220VAC
Lovato 11B145L00220220 heavy-duty three-pole industrial contactor with integrated G495 mechanical latch, 150 A AC-3 rating and 220-240 V AC/DC coil for industrial motor control and power switching applications.
Why Choose the Lovato 11B145L00220220 Three-Pole Latching Power Contactor?
The Lovato 11B145L00220220 is a heavy-duty three-pole industrial latching power contactor designed for dependable 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 supplied with a factory-fitted G495 mechanical latch, allowing the contactor to maintain its switching position without continuous coil energisation.
Designed for OEM machine builders, switchboard manufacturers and industrial maintenance engineers, the contactor combines durable silver alloy contacts with a powerful electromagnetic operating mechanism for reliable performance in demanding industrial environments. It features a 220–240 V AC/DC operating coil together with a 110–125 V AC mechanical latch, making it suitable for applications requiring maintained contact operation.
With a 250 A AC-1 thermal current rating, a 150 A AC-3 operational current, three normally open (3NO) main contacts, an integrated mechanical latch and a 220–240 V AC/DC control coil, the 11B145L00220220 is ideal for switching large motors, pumps, compressors and industrial power circuits. Its heavy-duty screw-mounted construction enables secure installation within electrical control panels and switchboards.
