General Duty Safety Switches

General duty safety switches are designed for residential and commercial applications where durability and economy are prime considerations. Typical loads are lighting, air conditioning and appliances. When equipped with fuses, over-current and short circuit protection is also available. The switches are also suitable as service equipment when equipped with a factory-installed neutral assembly or a field-installed equipment grounding kit.
