Block and IT. Electro-Mechanical Coil
Controller as a Full Voltage Non-
reversing (FVNR) or Full Voltage
Reversing (FVR) device. Size 00 to Size
4 Contact Blocks combined with Coil
Controllers (factory or field assembled)
are stand-alone Contactors. Only the
Size 5 Contactors have internal
factory assembled coil controllers.
