The ABB VE5-2 is a mechanical and electrical interlock unit designed for compatible ABB contactor combinations. When fitted between two contactors, its mechanical mechanism prevents one contactor from closing while the other is closed. The unit also includes two normally closed (NC) auxiliary contacts, which can be wired into the control circuit to provide electrical interlocking. Together, these features help ensure that the contactors in a switching arrangement do not operate at the same time.

Identified by ABB part number 1SBN030210R1000, the VE5-2 is listed for compatible AX contactors in the A45–A110 range. Its specifications include screw terminals and a conventional free-air thermal current (Ith) of 16 A at 40°C. ABB specifies horizontal mounting for the interlocked contactors.

The mounting rail or plate is not supplied. Some contactor combinations also have restrictions when installed on symmetrical rail, so check the approved combination and mounting details before purchase or installation. Ahmedabad Electric Corporation supplies ABB switchgear and automation products and can help confirm availability and compatibility for your application.
