Why Choose the Lovato 11B1250424110 B1250 Power Contactor?
The Lovato 11B1250424110 is a heavy-duty four-pole power contactor engineered for dependable switching of exceptionally high-current industrial electrical loads. Part of the robust Lovato B1250 contactor series, this model provides an IEC AC-1 operating current rating of 1250 A and features a 110–125 V AC, 50/60 Hz operating coil.
Designed for demanding industrial power-control applications, the B1250 contactor combines substantial switching capacity with reliable mechanical and electrical performance. Its four normally open main poles enable simultaneous control of four conductors, while the integrated 2NO + 4NC auxiliary contacts support signalling, electrical interlocking and control-system feedback.
With a conventional free-air thermal current of 1250 A at temperatures up to 40°C, a rated insulation voltage of 1000 V and an impulse withstand voltage of 8 kV, the 11B1250424110 is suitable for high-power switchboards, industrial heating systems, distribution equipment and heavy process machinery.

Reliable Four-Pole High-Current Power Control
Power contactors such as the Lovato 11B1250424110 allow high-current industrial loads to be switched using a lower-power electrical control circuit. Its four-pole design enables multiple conductors to be switched together, making it suitable for three-phase systems that also require neutral switching and other multi-pole power-control arrangements.
The integrated auxiliary contacts can provide contactor status indication, electrical interlocking and feedback to automation equipment. Combined with its high AC-1 current rating, robust construction and screw-mounted installation, the B1250 contactor supports dependable operation in heavy industrial power systems.
Typical Applications
- Four-pole industrial power-distribution systems.
- Three-phase and neutral load switching.
- Industrial heating and resistive load systems.
- High-current switchboards and control panels.
- Heavy production and processing machinery.
- Power generation and energy-management equipment.
