Bussmann LPJ-12SPI 12 Amp 600V AC Class J Time-Delay Fuse

The Bussmann LPJ-12SPI is a Class J time-delay fuse designed to provide reliable overcurrent protection for electrical systems operating at up to 600 volts AC. This low-peak, dual-element fuse is rated for 12 amps and features current-limiting technology that helps protect sensitive equipment from damaging short-circuit currents.

Key Features:

• 12 amp current rating with 600V AC maximum voltage
• Class J fuse with time-delay (dual-element) for motor and transformer circuit protection
• Current-limiting design reduces potential damage during fault conditions
• 200kA interrupting rating at 600V AC for superior short-circuit protection
• Rejection-style design prevents incorrect fuse substitution
• UL Listed and meets NEC requirements for Class J fuses
• Compact dimensions fit standard Class J fuse clips and blocks

Class J fuses are commonly used in motor control centers, panel boards, and combination starters where space is limited and high interrupting capacity is required. The time-delay characteristic allows temporary inrush currents from motors and transformers while providing fast protection against short circuits.
