Description
The ABB VM96-4 (Product ID: 1SBN033405T1000) is a mechanical interlock unit engineered for interlocking two 3-pole or 4-pole contactors side-by-side without increasing the total assembly width. Designed for medium-to-large industrial motor control applications, when mounted between two contactors, the VM96-4 positively prevents one contactor from closing as long as the opposing contactor is energized and closed.
The interlock unit includes two fixing clips (BB4) and is fully compatible across ABB AF40 … AF96, AFC40 … AFC96, and AFS40 … AFS96 contactor frames.
Key Features
- Zero-Width Mechanical Interlocking: Interlocks two contactors side-by-side without adding extra width to the panel layout.
- Positive Interlock Action: Physically prevents simultaneous closure of paired contactors for safe reversing and transfer switching.
- Broad Contactor Compatibility: Designed for use across ABB AF, AFC, and AFS series contactors from AF40 through AF96 (3-pole and 4-pole).
- Included Fixing Clips: Supplied complete with two (2) BB4 fixing clips for secure and rapid mechanical installation.
