ABB mini reversing contactors are compact and powerful contactors. They are ideally suited for applications where reliability is a must and space is at a premium. The dimensions, technical features and the variety of the assortment provide customers a high flexibility in a wide-range of applications.
The mini reversing contactors VB6, VB7 are designed for motor powers of up to 5.5 kW (AC-3).
All mini reversing contactors are offered with two different mechanical interlocks:
- VB6/VB7: normal interlock
- VB6A/VB7A: interlock with mechanical safety blocking function
The mechanical interlock between the two contactors mechanically prevents switch-on of one contactor for as long as the other contactor is still on and vice versa.
VB6/VBC6 Mini Reversing Contactors for switching:
- AC-3 loads up to 4 kW / 400 V
VB7/VBC7 Mini Reversing Contactors for switching:
- AC-3 loads up to 5.5 kW / 400 V
