ABB B6 VB6 Contactor, 240 V ac Coil, 3-Pole, 20 A, 4 kW, 3NO, 690 V ac

The mechanical lock between the two contactors prevents one of the contactors from switching on, as long as the other is still switched on and vice versa.
Switching over reversing contactors too quickly poses the risk of a phase short circuit.
This is the case if the arc of the contactor switching off has not yet extinguished and the contacts of the contactor switching on are already closed.
To avoid this risk, the two contactor coils must be switched to idle for a minimum of 50 ms during the switchover process and electrically locked against each other.

This contactor is a compact, versatile solution designed to control three-phase motor loads up to 4kW. Operating at a coil voltage of 240V AC, it features three main poles and one auxiliary contact. With dimensions of 57.5mm in length, 96.5mm in width, and 46.5mm in depth, this contactor is suitable for a variety of setups.
