Arrow Hart AH30MS1B Disconnect Switch

Arrow Hart AH30MS1B is a non-fusible manual motor-control disconnect switch rated for 30 amperes at up to 600 VAC, configured as a 3-pole, 3-phase device. This model ships without auxiliary contacts, offering a straightforward primary disconnect that interrupts line voltage without extra contact options. As part of Arrow Hart’s 30 A/600 V disconnect family, the AH30MS1B is designed to isolate three-phase machinery such as motors, pumps, or conveyors for maintenance or safety shutdowns. Its non-fused construction provides a simple, reliable means to open or close a 3-phase circuit, typically mounted in a control panel or enclosure where a dedicated disconnect is required. Because there are no auxiliary contacts, the switch supports only the basic on/off function, which can simplify wiring and installation in suitable applications, while complying with standard three-phase power switching practices. In this configuration, the AH30MS1B offers a compact solution within Arrow Hart’s line of non-fused disconnect switches, delivering dependable isolation for 600 VAC class systems at 30 A.
