Why Choose the Lovato 11B630SL00220 Power Contactor?
The Lovato 11B630SL00220 is a heavy-duty three-pole industrial power contactor designed for reliable switching and control of high-current electrical loads in motor control, industrial automation and power distribution systems. As part of the robust Lovato B630 contactor series, it provides dependable performance for demanding industrial installations where high electrical capacity and long-term operational reliability are essential.
This contactor is equipped with an AC/DC control coil rated at 220–240 V and is predisposed for installation of the optional Lovato G495 mechanical latch. This flexible configuration allows the device to operate as a conventional electrically held contactor or to be adapted for maintained switching applications without continuous coil energisation.
With an IEC AC-3 operational current rating of 630 A at 400 V, an AC-3 motor power rating of 355 kW and an AC-1 thermal current rating of 800 A, the 11B630SL00220 is suitable for controlling large three-phase motors, production machinery and high-power industrial equipment.

Reliable High-Current Motor Control
Industrial contactors such as the Lovato 11B630SL00220 allow large motors and electrical loads to be switched using a lower-power control circuit. This enables equipment to be started, stopped and integrated into automated control systems without directly switching the main power conductors manually.
The dual-voltage AC/DC coil makes this contactor compatible with a broad range of industrial control architectures. Its provision for the G495 mechanical latch also allows it to be adapted for maintained switching applications where the contacts must remain closed without continuous coil power.
Typical Applications
- Large three-phase motor starters.
- Industrial manufacturing and processing machinery.
- Material handling and conveyor installations.
- Pumps, compressors and ventilation equipment.
- Motor control centres and industrial switchboards.
- Power distribution and high-current switching systems.
- OEM machinery and automated production equipment.
