11B4004SL00220 – 4P CONTACTOR 220/240V W/O LATCH
Lovato 11B4004SL00220 four-pole industrial contactor with 550A AC1 thermal current rating, 420A AC3 operational current, 220…240V AC/DC universal control coil and predisposition for G495 mechanical latch integration.
Why Choose the Lovato 11B4004SL00220 Contactor?
The Lovato 11B4004SL00220 is a heavy-duty four-pole industrial power contactor designed for dependable switching of high-current electrical loads in motor control, automation and power distribution applications. Part of the robust Lovato B400 contactor series, this model features a versatile 220–240 V AC/DC control coil.
The contactor is specially prepared for the installation of a Lovato G495 mechanical latch. This latch-ready configuration gives panel builders and system integrators the flexibility to add mechanically maintained switching when required, while allowing the contactor to be used conventionally when a latch is unnecessary.
With an IEC conventional thermal current rating of 550 A and an AC-3 operational rating of 420 A / 225 kW at 400 V, the Lovato 11B4004SL00220 is suitable for large industrial motors, resistive loads, switchboards and demanding electrical control installations.
Key Advantages
- Heavy-duty four-pole industrial contactor for high-current switching.
- 550 A AC-1 thermal current rating for demanding power applications.
- 420 A AC-3 operational current for industrial motor control.
- Supports motors rated up to 225 kW at 400 V.
- Prepared for installation of the Lovato G495 mechanical latch.
- 220–240 V AC/DC control coil offers flexible control-circuit compatibility.
Key Features
- Lovato B400 power contactor series.
- Four main power poles.
- 220–240 V AC/DC operating coil.
- Predisposed for a G495 mechanical latch.
- 550 A IEC AC-1 conventional thermal current.
- 420 A / 225 kW IEC AC-3 rating at 400 V.
- 1000 V rated insulation voltage.
- Screw-mounted construction for industrial panels and switchgear.
Reliable High-Current Switching for Industrial Systems
Industrial contactors such as the Lovato 11B4004SL00220 allow large motors and high-power electrical loads to be controlled through a comparatively low-power control circuit. This supports reliable remote operation, integration with automation equipment and coordinated control within motor control centres and industrial switchboards.
The contactor’s compatibility with the optional G495 mechanical latch also enables it to be adapted for maintained switching applications. When the appropriate latch is installed, the contactor position can be retained mechanically without requiring the operating coil to remain continuously energised.
Typical Applications
- Large industrial motor starters.
- Motor control centres and switchboards.
- Industrial automation and process machinery.
- High-current resistive load switching.
- Power distribution and electrical control panels.
- Maintained switching systems using an optional G495 latch.
