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 motors. The time-delay design can carry an overload...

Detects phase current or ground-fault current. (200-A primary)

The L50QS 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. These fuses protect power converters, drives, and control...

Littelfuse LLNRK and LLSRK series POWR-PRO™ fuses provide superior overload and short circuit protection for service entrance, main, feeder and general-purpose branch circuits up to 600 amperes.

Space saving POWR-GARD 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 fuses provide fast-acting overload and short...

The SE-701 is a microprocessor-based ground-fault monitor for resistance-grounded and solidly grounded systems. It is uniquely suited for use on systems with significant harmonic content. Its output relay can operate in the fail-safe or non-fail-safe...

The PGA-LS10 series arc-detection point sensors are capable of detecting light from every angle in front of them due to the shape of the cylindrical lens on the front of the sensor. These sensors are installed and positioned in switchboards to give them...

The all-new LLSRK_ID series fuse is the most advanced Class RK1 fuse available today providing unparalleled performance and protection to modern circuits. The patented Indicator™ technology provides instant identification of a blown fuse greatly...

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 indicating version, see FLNR_ID series.

The time-delay, dual-element IDSR series fuses combine a 600 V dc capability with indication to provide an ideal solution for many dc applications. These fuses offer a patented, state-of-the-art, solid-state design with maximum reliability and superior...

KLNR/KLSR series RK1 fast-acting 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. When used to protect inductive loads...

The 102A is a 3-phase, auto-ranging, dual-range voltage monitor that protects 190-400VAC, 50/60Hz motors regardless of size. The product provides a user selectable nominal voltage setpoint and the voltage monitor automatically selects between the 200V...

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 pops out 0.3" when the fuse opens, providing a visual...
