BER65-4 is an ABB connection set accessory for reversing contactors, used to link the main poles of two 3-pole ABB AF-series contactors to implement a reversing function (for example two AF40 units). The part is designed as a screw-terminal AF(C) accessory, enabling straightforward wiring in control circuits for motor start/stop applications. In ABB catalogs, BER65-4 appears as an alternate catalog number for this reversing-contactors connection set, confirming its role as a specialized interconnection accessory rather than a molded case circuit breaker.
