Why Choose the Lovato 11B1454SL00220 Four-Pole Power Contactor?
The Lovato 11B1454SL00220 is a heavy-duty four-pole industrial power contactor engineered 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 version is predisposed for the installation of the optional G495 mechanical latch, allowing future conversion to mechanically latched operation where 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 provide dependable switching performance under demanding industrial conditions. The integrated 220–240 V AC/DC operating coil offers flexibility for both AC and DC control systems.
With a 250 A AC-1 thermal current rating, a 150 A AC-3 operational current, four normally open (4NO) main contacts and a 220–240 V AC/DC control coil, the 11B1454SL00220 is ideal for switching large motors, heating systems and industrial power circuits. Its heavy-duty screw-mounted construction enables secure installation within industrial control panels and switchboards.
