ABB BEY65-4 Relay

ABB BEY65-4 Connection Set for Star-Delta Starter (order code 1SBN083413R2000) is an interlock and bridging kit designed for ABB AF65-series 3-pole contactors used in star-delta motor-start configurations. It comprises insulated connecting bridges formed from solid copper bar to physically link the delta and star sections, enabling proper star-to-delta wiring within the starter assembly. The kit is supplied as a single unit (Pkg qty 1) and weighs about 0.2 kg per piece, reflecting a compact, field-installable component suitable for mounting alongside the AF65 contactors. This BEY65-4 assembly is the designated connection set for star-delta starters and is explicitly identified in ABB catalogs for AF65-series starters, with the 1SBN083413R2000 order code ensuring compatibility with BEY65-4 configurations in three-pole line equipment. By providing the necessary bridging and interlock between delta and star contactors, BEY65-4 helps realize the star-delta starting sequence in industrial motor control panels, commonly installed in conjunction with ABB AF65 family starters to enable reliable, staged motor starting.
