KLDR Series time-delay fuses are designed to protect control transformers, solenoids, and similar inductive components with high-magnetizing currents during the first half-cycle. These small-sized...

The ARP Series is used in systems where equal run time for two motors is desirable. The selector switch allows selection of alternation of either load for continuous operation. LED’s indicate the...

KLSR series RK1 fuses were the earliest type of current-limiting fuse developed. Their single-element, silver link design enables them to provide fast-acting overload and short-circuit protection...

The FLSR series dual-element, time-delay UL Class RK5 fuses are the most widely used fuse class. They offer superior performance and excellent protection for all types of circuits, especially those...

The L25S series is a traditional North American bolted-style, high-speed fuse designed with POWR-SPEED® technology for protection of power semiconductor devices that are rated up to 250 V ac and up...

NLS series fuses provide low cost protection for general-purpose feeder and branch circuits when available short circuit currents are less than 50,000 amperes. They replace all Class H fuses which...

The FLNR series sets the standard for general purpose fuses. The dual-element design provides advanced short-circuit and overload protection. These time-delay fuses are also available in an...

Space-saving Class T fuses are the most compact fuses available in ratings above 30 amperes — less than one-third the size of comparable Class R fuses. When rated in accordance with the NEC, Class T...

The FLNR series sets the standard for general purpose fuses. The dual-element design provides advanced short-circuit and overload protection. These time-delay fuses are also available in an...

The FLA series fuses are 125 V ac, pin-indicating, time-delay fuses for protection of control circuit transformers, solenoids, and other circuits with high in-rush currents. A metal indicator pin...

The KLC series is a traditional North American-style, high-speed fuse designed with POWR-SPEED® technology for protection of power semiconductor devices that are rated up to 600 V ac. This is a round...

The SE-TA6ASF-WL series is a small-format, temperature-compensated, 12 W ground-check termination assembly with convenient mounting holes and wire leads. This assembly is ideal for use in...

The 350 series is a heavy-duty voltage monitor. This product should be used when high-current relays or dual contacts are required or when 480 V controls are used. Since the 350 series uses...

The BLF series fast-acting fuses supplement the primary branch-circuit fuse or breaker to provide backup overcurrent protection. These fuses also have the capability to limit currents with...

The FLSR_ID Indicator™ Series offers a patented, state-of-the-art, solid-state design with maximum reliability and superior performance characteristics. The dual-element design ensures advanced...

KLSR series RK1 fuses were the earliest type of current-limiting fuse developed. Their single-element, silver link design enables them to provide fast-acting overload and short-circuit protection...

The L70QS series is a POWR-SPEED® next-generation, high-speed fuse used for the protection of power semiconductor devices and is designed in the traditional, North American-bolted style package...

The FLM series 250 V fuses are designed to protect control circuit transformers, solenoids, and other circuits with high in-rush currents. They are also excellent for supplemental protection of small...
