Why Choose the Lovato 11B1454L00220220 Four-Pole Latching Power Contactor?
The Lovato 11B1454L00220220 is a heavy-duty four-pole industrial latching power contactor designed for reliable switching of high-current electrical loads in motor control, power distribution and industrial automation systems. Part of the robust Lovato B145 contactor series, this model is supplied with a factory-fitted mechanical latch, providing secure maintained switching without continuous coil energisation.
Designed for OEM machine builders, switchboard manufacturers and industrial maintenance engineers, the contactor combines durable contact materials with a high-performance electromagnetic operating mechanism for dependable switching under demanding operating conditions. The integrated 220–240 V AC/DC control coil and mechanical latch make it ideal for applications requiring maintained contact position during power interruptions.
With a 250 A AC-1 thermal current rating, a 150 A AC-3 operational current, four normally open (4NO) main contacts, an integrated mechanical latch (G495) and a 220–240 V AC/DC operating coil, the 11B1454L00220220 is suitable for switching large motors, resistive loads and industrial power circuits. Its robust screw-mounted construction enables secure installation inside industrial control panels and switchboards.
