Cutler-Hammer DG221NRB General Duty Safety Switch

The Cutler-Hammer DG221NRB general duty safety switch is a fusible disconnect rated for 30 A at 240 VAC in a 3-wire configuration. It uses external fuses to interrupt current and provide overcurrent protection while enabling safe isolation of power for maintenance or service. This model is part of Eaton’s Cutler-Hammer DG family and is intended for general-duty applications in commercial or light industrial settings that require a 30-amp, 240-volt disconnect. The 3-wire arrangement accommodates typical wiring in 240 V systems, supporting connections for circuits that feed equipment or control panels that rely on fusible protection. Suitable uses include general disconnects in panel feeders and other general-purpose installations where a reliable disconnection point is needed to safely isolate loads. The DG221NRB designation identifies the exact configuration within the DG line, reflecting a fusible, general-duty safety switch designed for standard 240 VAC circuits.
