10x38mm midget fuses help provide supplemental overcurrent protection and have the capability to limit currents with fast-acting reliability. 10x38mm midget fuses can be used in a variety of applications. Select a series below based on the electrical requirements of your system.
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 fast-acting reliability, opening within seconds of being exposed to overloads and short circuits. They are suitable for control circuit and instrument protection in dry (exhibiting little to no humidity) locations. The BLF fiber tube fuses are the lowest-priced midget fuses available.
The BLN Series 250 V ac fast-acting fuses provide low-cost overcurrent protection for military applications and control circuits. They supplement the primary branch-circuit fuse or breaker to provide additional backup protection. These fuses also have the capability to limit currents with fast-acting reliability.
The BLS Series fast-acting fuses are 1 ⅜” long in comparison to other midget fuses, which are 1 ½” long. They provide space-saving, low-cost protection for street lighting, metering, control and electronic circuits. These fuses open circuits quickly when surges are detected, providing exceptional security for equipment requiring fast overload protection.
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 indication of an open fuse. This built-in, blown-fuse indication quickly identifies which fuse or fuses within an electrical panel or system have blown. The time-delay design can carry an overload several times the normal load for a short period of time...
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 several times the normal load for a short period of time without blowing. The FLM fuses are non-indicating and may be used with an indicating fuse block to identify a blown fuse.
The FLQ series 500 V fuses are designed to provide supplemental overcurrent protection of control power transformers, solenoids, and circuits with high in-rush currents. They also provide excellent supplemental protection of small motors. These time-delay fuses can carry an overload several times the normal load for a short period of time without blowing. The FLQ fuses are non-indicating and may be used with an indicating fuse block to identify a blown fuse. Note that UL and ...
The FLU series fast-acting 1000 V fuses are specifically designed for the protection of multimeters. These midget fuses supplement the primary branch-circuit fuse or breaker to provide backup overcurrent protection. They also have the capability to limit currents with fast-acting reliability...
The KLK series fast-acting fuses are designed specifically for the protection of control circuits, street lighting, HID lighting, computers, and other applications without high in-rush currents. These midget fuses also have high-interrupting and current-limiting capability. They are intended to supplement the primary branch-circuit fuse or breaker to provide backup overcurrent protection. The KLK fuses are non-indicating and may be used with an indicating fuse block to identify a...
The KLKD series fast-acting 600 V ac/dc fuses are used in solar combiner boxes and in circuits with dc fault currents up to 50,000 A. These fuses are designed to meet both the UL and IEC photovoltaic fuse specifications and are available in standard and board-mount configurations. The KLKD midget fuses also have high-interrupting and current-limiting capability. They are intended to supplement the primary branch-circuit fuse or breaker to provide backup overcurrent protection...
The 600 V KLQ series midget fuses are 1 ⅜” long in comparison to other midget fuses, which are 1 ½” long. They are the same physical size as the Littelfuse BLS fuse but carry an increased time-delay capability to handle transient and in-rush currents. They are ideally suited to protect gaseous vapor fixtures, HID ballasts, and other electronic and lighting circuits. These fuses are ideal for systems requiring 600 V ac or less.
The SPF Solar Protection Fuse series has been specifically designed for the protection of photovoltaic (PV) systems. This family of Midget style fuses (10x38 mm) can safely protect PV (photovoltaic) modules and conductors from reverse overcurrent conditions.
