11B250L0060C48 – 3P CONTACTOR 60V C/W LATCH 48VDC
Lovato 11B250L0060C48 three-pole industrial contactor with integrated G495 mechanical latch, 265A AC3 operational current rating and 60V AC/DC universal control coil for industrial automation and motor control systems.
Why Choose the Lovato 11B250L0060C48 Three-Pole Mechanically Latched Contactor?
The Lovato 11B250L0060C48 is a heavy-duty three-pole industrial power contactor engineered for reliable switching of high-current electrical loads in industrial motor control, automation and power distribution systems. As part of the proven Lovato B250 contactor series, this version is supplied with a factory-fitted G495 mechanical latch for applications requiring maintained switching.
The contactor incorporates a universal 60 V AC/DC operating coil together with a 48 V DC mechanical latch. Once energised, the mechanical latch holds the contactor in position without continuous coil power, helping reduce energy consumption while maintaining reliable circuit operation.
With an IEC AC-3 operational current rating of 265 A, a 350 A AC-1 thermal current rating and three normally open main poles, the 11B250L0060C48 is ideal for switching large motors, industrial drives and high-current power circuits.

Reliable Mechanically Latched Power Switching
Mechanically latched contactors remain in their selected operating position after the initial control signal has been removed. This reduces continuous control power consumption while ensuring critical loads remain energised until a deliberate release command is applied.
The Lovato 11B250L0060C48 combines high-current switching capability with a factory-installed G495 mechanical latch, making it ideal for industrial motor control centres, power distribution equipment and automation systems requiring maintained switching.
Typical Applications
- Industrial motor control centres.
- Power distribution systems.
- Pumps, compressors and fan control.
- Conveyor and material handling equipment.
- Industrial automation machinery.
- Applications requiring mechanically maintained switching.
