BZ0WKUAA is an auxiliary and alarm contact block designed for Fuji Electric manual motor starters (BM3R and BM3V series). This combined contact block integrates both auxiliary contacts that are linked to the ON/OFF operation of the motor starter and alarm contacts that operate independently when the starter trips due to overload, phase loss, or short-circuit. The block features a 1NO (normally open) auxiliary contact and 1NO alarm contact configuration, with an indication window that displays when the alarm contact operates. It mounts on the left side of the starter and has a mass of 45 g. The rated operational current varies by voltage: 5 A at 48 V AC (AC-15), 3 A at 125 V AC, 1.5 A at 230 V AC, and 1.38 A at 48 V DC (DC-13). This accessory is commonly used in motor control applications to provide both operational feedback and fault indication, enabling comprehensive motor protection and diagnostics in industrial motor control systems.
