Circuit Breakers

5mm x 20mm glass time delay/low breaking capacity electronic fuse. Time delay feature. 250V. UL (Underwriter's Laboratories) listed.

Fast acting glass fuses. Ideal for testers and other small electronic equipment requiring fuses. 5 mm Dia. x 20mm L. UL (Underwriter's Laboratories) listed.

Medium time delay (slow blow) electronic fuse. Features nickel-plated brass endcap and glass tube construction.

Limitron heavy-duty, fast-acting KTK supplemental midget fuse. Fuse has a high-strength melamine tube for high interrupting rating. 600V maximum. All fuses measure 1-1/2 In. L. x 13/32 In. Dia. Typical applications include control circuits, lighting...

Time-delay (slow blow) MDL glass fuse for use with computers, satellite dishes, office equipment. 1-1/4" L x 1/4" diameter, UL (Underwriter's Laboratories) listed.

Heavy-duty Fustat S-Type time delay, dual element, plug fuse. Features a rejection base for critical circuit protection such as air conditioners, furnace blowers, swimming pool pumps, deep freezers, or any circuit where motors turn on and off frequently...

Heavy-duty Fusetron Type-T time delay, dual element, Edison base plug fuse. Ideal for critical circuit protection for swamp coolers, air conditioners, furnace blowers, swimming pool pumps, deep freezers, or any circuit where motors turn On and Off...

Heavy-duty Fusetron, dual element, time delay FRN-R fuse for motor protection. Helps protect motors from burnout caused by overloads or single phasing. Time delay feature allows the initial startup surge for typical motors to pass, but opens prior to...

Heavy-duty time delay FRN-R easyID fuse makes it easy to locate the open fuse when the power goes out. The separate overload and short-circuit elements of the Fusetron fuse allow harmless, temporary overloads to pass while reacting quickly to...

Heavy-duty Fusetron, dual element, time delay FRN-R fuse for motor protection. Helps protect motors from burnout caused by overloads or single phasing. Time delay feature allows the initial startup surge for typical motors to pass, but opens prior to...

General-purpose one-time, NON fuse. For use in non-current limiting lighting circuits, main panel protections, or other circuits that do not contain large electric motors. No time delay. UL (Underwriter's Laboratories) listed Class K5 (50,000 AIR) with...
