Load control, transfer and disconnect devices can switch large loads and maintain maximum safety by ensuring a circuit is completely de-energized for service. These devices carry various UL ratings for specific uses in electrical systems.
Disconnects and switches maintain maximum safety by ensuring a circuit is completely de-energized for service. UL 98, 498, 508, and 1008 rated fused and non-fused disconnects provide suitable disconnecting means up to 600A for the most demanding applications.

Transfer switches provide safe, manually operated transfer and disconnection of sources, even under load. These UL 1008 rated switches are ideal for generator switching in systems where power loss could cause business disruption.
UL 98 and UL 489 fusible disconnects provide a high short-circuit current rating, able to operate under load to provide safe isolation and circuit protection. In ratings up to 600A, these disconnect switches are available with up to 4 poles; handles, shafts and fuses are sold separately.
UL 98 non-fusible disconnects safely control and disconnect circuits while under load. In ratings up to 600A, these disconnects are available with up to 4 poles with a high short-circuit current rating; handles and shafts are sold separately.
UL 98 DC-rated non-fusible disconnects are load-break capable and provide a high short-circuit current rating. These rotary disconnect switches, rated up to 250A at 1000 VDC, are front-operated with a direct-mount or remote handle (sold separately).
UL 508 non-fusible disconnects and manual motor controllers are rated to operate while under load to provide safe isolation in motor control circuits. These 3-pole rotary switches, in DIN rail or door-mount options, are available in ratings up to 125A (50hp); handles and shafts are sold separately.
UL 508 enclosed non-fusible disconnects are perfect for safely controlling and disconnecting motors. These 3-pole rotary enclosed disconnect switches, pre-mounted in an enclosure, are available in ratings up to 125A, with a 5kA SCCR rating.
Motor transfer cam switches allow seamless changeover from one motor to another; motor reversing switches allow smooth direction change. Rotary cam switches are available with 2 or 3 poles, with a 5kA SCCR rating.
Rotary handle and shaft assemblies make it possible to externally operate disconnects or controllers installed in an enclosure. Products are available as a single handle or in handle kits with handle, shaft, brackets, and screws included. Accessories include adapters, shaft supports, and alignment guides.
Auxiliary contacts are accessory contacts used to signal external monitoring equipment when the disconnect or switch is open or closed. Additional fourth pole, neutral, and ground pole modules are available with ratings up to 125A.
Line and load side terminal covers act as guards to shield the operator from touching live terminations.
Mounting and connection accessories include enclosures and mounting feet, disconnect door mounting hardware, bridging bars for manual transfer switches, and replacement screws.
Line and load side box lugs are available with one or two openings that accommodate a range of wire sizes for SIRCOVER UL 1008 manual transfer switches.
