VEM4 electrical-mechanical interlock for interlocking two AF contactors. The VEM4 kit includes a VM4 mechanical interlock unit with 2 mounting clips (BB4) and a VE4 electrical interlock kit with A2-A2 connection. Attaching the electrical interlock kit to the front of the contactor connects the two built-in normally closed interlock contacts to the two coils. The VE4 block must be used with an A2-A2 connection to accommodate the electrical wiring diagram.
