The ABB VB7A-30-10-84 (SKU: GJL1311911R8104) is a compact and highly reliable reversing mini contactor designed for forward and reverse control of three-phase motors in industrial automation systems. As part of the proven ABB VB7A mini contactor series, it combines two mechanically interlocked contactors into a single assembly, delivering dependable motor reversing while minimising control panel space requirements.
Designed for OEM machine builders, panel manufacturers and maintenance engineers, the VB7A-30-10-84 offers excellent reliability, straightforward installation and long service life. Its integrated mechanical interlock and safety blocking mechanism prevent simultaneous operation of both contactors, helping protect motors and electrical equipment during reversing applications.
With a 5.5 kW AC-3 motor rating at 400 V, a 110-127 V AC control coil and a 3 NO + 1 NO contact configuration, the VB7A-30-10-84 is ideal for conveyors, pumps, fans, hoists, packaging machinery and other industrial equipment requiring reliable forward and reverse motor control.
Reversing contactors provide safe forward and reverse operation of three-phase motors by mechanically preventing both contactors from closing simultaneously. This protects connected equipment while ensuring dependable directional control for industrial machinery.
The ABB VB7A series is widely used by machine builders and panel manufacturers thanks to its compact design, silent coil technology, switch position indication and dependable long-term performance in demanding industrial environments.
