Lovato 11B125024110 heavy-duty three-pole industrial contactor with 110–125 V AC coil, 1250 A AC1 operational current rating and integrated 2NO + 4NC auxiliary contacts for industrial power switching applications.
£8,923.82
The Lovato 11B125024110 is a heavy-duty three-pole power contactor engineered for switching exceptionally high-current industrial electrical loads. Part of the robust Lovato B1250 contactor series, it provides a conventional free-air thermal current rating of 1250 A and uses a 110–125 V AC, 50/60 Hz control coil.
Designed for demanding industrial installations, the B1250 contactor combines substantial switching capacity with reliable mechanical and electrical performance. Its integrated 2NO + 4NC auxiliary contacts provide additional signalling, interlocking and control options, helping simplify integration into complex automation and power-control systems.
With an AC-1 operational 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 11B125024110 is suited to high-power control panels, industrial distribution systems and heavy machinery requiring dependable three-phase load switching.
Power contactors such as the Lovato 11B125024110 allow high-current industrial loads to be switched using a lower-power electrical control circuit. The contactor’s 1250 A AC-1 rating makes it suitable for controlling resistive loads, heating systems, power-distribution circuits and other demanding industrial equipment.
The built-in auxiliary contacts can be used for status indication, electrical interlocking and control-sequence feedback. Its high making and breaking capacities, long mechanical life and robust screw-mounted construction support dependable operation in heavy industrial control systems.
