Why Choose the Lovato 11B63010000048 Power Contactor?
The Lovato 11B63010000048 is a heavy-duty three-pole power contactor designed for reliable switching of high-current electrical loads in industrial control, automation and power distribution systems. Part of the robust Lovato B6301000 contactor series, it is engineered for installations requiring high current capacity, dependable operation and long service life.
This contactor has an IEC conventional free-air thermal current rating of 1000 A in AC-1 duty, making it suitable for switching resistive loads, industrial heating systems and other high-power circuits. Its three normally open main poles provide reliable control of three-phase electrical supplies, while the electronically controlled coil supports both AC and DC control voltages.
With a rated coil voltage of 48 V AC/DC, the 11B63010000048 is well suited to low-voltage industrial control circuits. Its screw-mounted construction, high insulation rating and substantial switching capacity make it suitable for installation in motor control centres, switchboards and heavy industrial machinery.

Reliable Switching for High-Power Industrial Loads
Power contactors such as the Lovato 11B63010000048 allow high-current equipment to be switched remotely using a lower-power control circuit. Applying the specified voltage to the contactor coil closes the three main contacts, allowing electrical power to flow to the connected load.
The B6301000 series is designed for heavy industrial applications where robust construction and dependable switching are essential. Its high current rating, AC/DC coil and wide operating temperature range support integration into motor control centres, distribution systems and automated production equipment.
Typical Applications
- Industrial motor control centres.
- High-power electrical heating systems.
- Industrial switchboards and distribution panels.
- Heavy machinery and production equipment.
- Pumps, compressors and ventilation systems.
- Process automation and manufacturing plants.
