Bryant BRY460MI9W Mechanical Interlock Assembly

BRY460MI9W is a 60 A, 240 V (nominal) pin‑and‑sleeve mechanical interlock assembly for three‑pole, four‑wire systems. This rotary, enclosed interlock is load‑break capable and pairs with a Bryant pin‑and‑sleeve receptacle to enforce correct operating sequence in motor‑disconnect applications. It features a 9‑hour pin‑and‑sleeve receptacle, a 10 kA SCCR rating, and a robust housing measuring 11.9 in long by 6.9 in wide by 8.6 in high. The device is designed for 240 VAC operation (catalogs also list a 250 V rating) and uses a 3P/4W configuration, with mating plugs sold separately. Common applications include industrial motor control circuits and safety interlock assemblies in switchgear where reliable interlock between disconnect devices is required.
