Semiconductor Fuses with Higher Amperage Ratings in Smaller Case Sizes

The Littelfuse award-winning Powr-Speed PSR series of high-speed semiconductor square-body fuses keeps growing. There are new amperage ratings for customers who need higher current in smaller case sizes. They offer a more economical solution to protect sensitive semiconductor devices from overcurrent surges and extend the life of critical power equipment.

How to Properly Protect a BESS Power Circuit from Overcurrents

A battery energy storage system requires proper circuit protection. Overcurrents not only frequently damage systems, but are also the culprit of downtime, which is detrimental to a company’s bottom line. Fuses are a great way to protect a system simply and cost-effectively. Learn how to properly protect a BESS power circuit from overcurrents with this application guide.

ESR Fuses Offer a Wider Range of Protection for Battery Racks

The Littelfuse Energy Storage Rack (ESR) series of fuses are designed specifically to protect battery racks from a range of fault currents to help prevent equipment damage or expensive system failures. The 1500 V dc high-speed square body fuse is extremely fast-acting to respond quickly to safeguard the battery module.

Calculating Solar Fuse Sizes for Optimum Protection

Every photovoltaic (PV) power application must use fuses that are properly sized to its system. When you use the incorrect fuse size (or a standard non-PV fuse), you put the system’s reliability and safety in jeopardy.

275 Bolted and DIN Mount High-Speed Fuses Now Available

Engineered to protect sensitive semiconductor devices, the Littelfuse PSR high-speed fuse line now includes 275 bolted and DIN blade mount options.

POWR-SPEED® High-Speed Fuses

Optimized for performance and efficiency, POWR-SPEED ® High-Speed (Semiconductor) Fuses are ideal for modern-day sensitive power electronics devices that require superior protection against overcurrent. This family of fuses offers extreme current limiting protection, balanced performance for longevity, and are available in direct bus-bar mount flush-end designs to meet global market needs.

Littelfuse DIN Releasable Fuse Blocks

New DIN Releasable Fuse Blocks available from Littelfuse save installation time and effort. These blocks mount securely to standard 35mm “hat” DIN rails without extra adapters. The spring-free release mechanism allows for individual block installation and replacement without removing adjacent components. Configurations are available for Class CC, Class G, and Midget fuses.

Littelfuse Launches 1500 Volt Solar String Fuse and Holder Rated 35 to 60 Amperage

The 1500 V dc SPXV series solar string fuses, with 35 to 60 amperage, protect photovoltaic (PV) installations from overloads and short circuits to minimize damage to solar panels. These 20 x 127 mm fuses are designed to integrate into an LFXV15 fuse block and cover holder.
