Why Choose the Lovato 11B145400110 B145 Four-Pole Power Contactor?
The Lovato 11B145400110 is a heavy-duty four-pole power contactor designed for dependable switching of high-current industrial electrical loads. Part of the established Lovato B145 contactor series, this model provides an IEC AC-1 operating current rating of 250 A and features a versatile 110–125 V AC/DC operating coil.
Its four-pole configuration enables four conductors to be switched simultaneously, making the contactor suitable for three-phase and neutral circuits, industrial heating systems and other multi-pole load-control applications. The AC/DC coil supports integration with either alternating-current or direct-current control systems within the specified voltage range.
With a rated insulation voltage of 1000 V, an impulse withstand voltage of 8 kV and a conventional free-air thermal current of 250 A at temperatures up to 40°C, the 11B145400110 provides robust performance for industrial switchboards, automation panels and heavy machinery.
