Square D HUB361RB Heavy Duty Safety Switch, Switch not fusible, HD 600V 30A 3-Pole NEMA3R.

Square D® heavy duty safety switches are designed for commercial and industrial applications where maximum performance and continuity of service is vital. Like our general duty switches, they too can provide over-current and short circuit protection when equipped with fuses. When equipped with either a factory-installed solid neutral assembly or a field-installed equipment grounding kit (some exceptions apply), the switches are also suitable for use as service equipment.
