LPSM POWR-SAFE "Dead Front" Fuseholder for Midget Fuses

Littelfuse POWR-SAFE “Dead Front” holders provide optimum protection to personnel. Indicating and non-indicating versions are available in 1,2,3, or 4 poles for Midget fuses.

LLSRK ID Time Delay Indicator Fuse

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 enhancing system up time, while the precision formed short circuit elements virtually eliminate damage to components from unexpected electrical faults.

LF Series Covers

Littelfuse fuse block covers protect personnel from accidentally coming into contact with energized parts. Covers are for use with various UL class fuse blocks.

PGR 8800 Arc- Flash Relay

The PGR-8800 reliably detects developing Arc-Flash incidents without nuisance tripping by looking for a combination of excess light and current. Phase-current-transformer inputs are provided for current-constrained arc-flash protection and, when so equipped, a programmable definite-time overcurrent function can be enabled. An optical sensor on the PGR-8800 and adjustable trip level reduce the chance of nuisance tripping by setting a threshold for ambient light. Sensors, inputs, and connections are monitored to ensure fail-safe operation. A secondary solid-state trip circuit provides a redundant trip path. A USB port is used for configuration and access event logs and graphs.
