SK829071-A

The ABB VH145 Mechanical Interlock Unit is an accessory for compatible ABB EK contactors. Fitted between two horizontally mounted contactors, it mechanically prevents one contactor from closing while the other remains closed. This helps ensure that both contactors do not operate simultaneously in switching arrangements that require mutually exclusive operation.

The VH145 is identified by ABB order code SK829071-A. ABB’s catalogue lists it for compatible EK110/EK150 contactor pairings. Before purchase or installation, check the exact contactor models and the required mounting arrangement against ABB’s compatibility information. The interlock should be selected to match the contactor combination in the application.

Ahmedabad Electric Corporation supplies ABB switchgear and automation products and can help you check the availability and suitability of the VH145 for your installation.
