Abb Latching Power Relay with 2NC Contacts for AF09-AF38 VEM4 45394

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:

• VM4 mechanical locking unit with 2 mounting clips (BB4)
• Electric lock block VE4 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 connection A2-A2 to comply with the electrical connection diagram.
