ABB Reversing Contactor VB6A-30-10 220-240VAC 3-Pole 1NO 9A 4kW GJL1211911R8100

When you need to reverse a three-phase motor, the last thing you want is a tangle of separate contactors and wiring. The ABB VB6A-30-10 packs two mechanically interlocked contactors into one compact unit, so you get safe, reliable reversing without the extra assembly work.

Who is it for

This reversing contactor is made for panel builders, machine manufacturers, and maintenance engineers who control motor direction in conveyors, hoists, machine tools, and similar equipment. It fits neatly into industrial control cabinets where DIN rail or screw mounting is standard.

Main features

• Reversing contactor with 3 main poles and 1 normally open (NO) auxiliary contact
• Coil voltage: 220-240 V AC, 50/60 Hz
• Rated operational current: 9 A (AC-3, 400 V)
• Rated operational power: 4 kW (AC-3, 400 V)
• Mechanical interlock prevents both directions from energizing at the same time
• Compact design saves valuable panel space

Specifications

• Number of main poles: 3
• Auxiliary contacts: 1 NO
• Rated insulation voltage (Ui): 690 V
• Rated impulse withstand voltage (Uimp): 6 kV
• Terminal type: screw terminals
• Mounting: DIN rail or screw mounting
• Degree of protection: IP20
• Operating temperature range: -25 to +55 °C
• Mechanical durability: 10 million cycles
• Electrical durability (AC-3): 1.2 million cycles

How to use

Wire the main poles to your motor supply and connect the coil to your 220-240 V AC control circuit. The built-in mechanical interlock ensures that only one direction can be active at a time, protecting your motor from short circuits. Mount it on a DIN rail for quick installation, or use screw mounting if your panel requires it. Make sure the enclosure has adequate ventilation to keep within the operating temperature range.

Tip: Always double-check that your control voltage matches the coil rating (220-240 V AC). For reversing applications, never bypass the mechanical interlock—it is your first line of defense against costly damage.
