Why Choose the ABB GJL1211901R0001 VB6-40-00-01 Mini Reversing Contactor?
The ABB GJL1211901R0001, also known as the VB6-40-00-01, is a compact mini reversing contactor designed for forward and reverse control of three-phase motors in industrial machinery, commercial equipment and building automation systems. As part of the ABB VB6 mini reversing contactor series, it combines two mechanically interlocked contactors in a space-saving assembly for dependable motor direction control.
This reversing contactor features four normally open main contacts (4 NO), a 24 V AC control coil and screw terminals for secure electrical connections. The mechanically interlocked design prevents simultaneous operation of the opposing contactors, while the compact construction, silent coil and switch position indication make the unit particularly suitable for control panels and machinery where installation space is limited.
With the ability to control three-phase motor loads up to 4 kW at 400 V AC-3, the VB6-40-00-01 provides a compact solution for reversing applications such as conveyors, doors, positioning systems and machine drives. Its integrated provision for rail or wall mounting enables straightforward installation in a wide range of electrical control systems.

Reliable Forward and Reverse Motor Control
Reversing contactors such as the ABB VB6-40-00-01 allow the direction of a three-phase motor to be changed by reversing the phase sequence supplied to the motor. The forward and reverse contactors are mechanically interlocked to prevent both switching states from being engaged simultaneously, helping provide safe and dependable directional motor control.
The ABB VB6 series is designed for applications where reliability is important and installation space is at a premium. Its compact construction and integrated reversing functionality make the GJL1211901R0001 particularly useful for machine builders and automation engineers requiring forward and reverse motor operation without the space requirements of separate conventional contactors and interlocking hardware.
Typical Applications
- Forward and reverse control of three-phase motors.
- Industrial conveyors and material handling systems.
- Doors, gates and shutter control systems.
- Hoisting and positioning equipment.
- Packaging and production machinery.
- Machine tools and automated equipment.
- Building automation and commercial equipment.
- OEM machinery and compact motor control panels.
