VEM4 is a mechanical and electrical interlocking set for side-by-side interlocking without additional width of two AF09 … AF38 or AFC09 … AFC38 contacts.

The VEM4 set includes a VM4 mechanical locking unit with 2 mounting clips (BB4) and a VE4 electrical locking block with A2-A2 connection.
Mounting the electrical interlock block on the front of the contacts connects the 2 built-in NC interlock contacts to the two coils saving up to 50% less wiring compared to conventional electrical interlocking.

The VE4 block must be used with A2-A2 connection to comply with the electrical connection diagram.
