Arrow Hart AH30MS1B Manual Motor Controller Disconnect

Arrow Hart AH30MS1B is a 30 Amp, 600 VAC non-fused manual motor controller disconnect switch used to provide a safe, hand-operated disconnect for motor circuits in industrial equipment. It is housed in a gray NEMA enclosure (GY) and configured as a 3-pole device suitable for single-phase or three-phase motor loads up to 30 A at voltages up to 600 V AC. A related model, AH30MS1B-M2, adds an auxiliary contact set for signaling or control applications, expanding integration with control logic or indicators. This product sits in Arrow Hart’s line of non-fused motor control disconnects (now part of Eaton Wiring Devices), with higher-current variants in the same family available for larger motors. Because it is non-fused, protective fusing must be provided upstream and the device is intended for ON/OFF control of motor power in industrial environments, including use in lockout/tagout procedures where a readily accessible disconnect is required.
