Safety Switch & Disconnectors

Safety Switches & Disconnects — New & Used

Safety switches and disconnects provide essential protection and isolation for electrical equipment during maintenance, emergencies, and power interruptions. Designed to meet NEC and OSHA standards, these devices safely cut power to machinery or circuits, preventing accidental energization. Available in fusible and non-fusible configurations, indoor and outdoor NEMA-rated enclosures, and a variety of amp ratings for single- or three-phase systems.
