11B11540060 – 3P CONTACTOR B115.00 60V
Lovato 11B11540060 is a four-pole B115 power contactor with a 160 A AC-1 rating and a 60 V AC/DC coil for industrial load switching and motor-control applications.
Why Choose the Lovato 11B11540060 Four-Pole Contactor?
The Lovato 11B11540060 is a heavy-duty four-pole power contactor designed for reliable switching of industrial electrical loads. Part of the Lovato B115 contactor series, it combines a high current capacity with a robust electromechanical design for demanding control-panel and automation applications.
With a conventional free-air thermal current of 160 A and an AC-3 operational current of 110 A at up to 440 V, this contactor can control resistive, inductive and motor loads. Its four main poles also make it suitable for applications requiring simultaneous multi-pole switching or the interruption of multiple conductors.
The 11B11540060 incorporates a 60 V AC/DC control coil, enabling operation from either alternating-current or direct-current control systems. Screw fixing, high mechanical endurance and compliance with recognised IEC, UL and CSA standards support dependable integration into industrial electrical installations.

Reliable Switching for Industrial Power Circuits
Power contactors allow high-current electrical loads to be controlled remotely through a lower-power control circuit. When the 60 V coil is energised, the four main contacts operate together to supply power to the connected equipment. De-energising the coil opens the contacts and disconnects the load.
The Lovato B115 platform is designed for repeated switching in industrial environments. Its high current capacity, long mechanical life and four-pole configuration make it suitable for machinery, heating equipment, distribution assemblies and motor-control systems that require dependable multi-pole operation.
Typical Applications
- Industrial motor starters and control panels.
- Resistive heating and furnace systems.
- Industrial lighting and power distribution circuits.
- Pumps, fans, compressors and conveyors.
- Machinery and production-line automation.
- Four-pole load switching and isolation systems.
