EATON LPJ-40SPI 40A CLASS J DUAL ELEMENT TIME-DELAY FUSE
Product Details

Resources
Bussmann Low-Peak™ Time Delay Fuse, Current Limiting, Series: LPJ-SPI, Indicating/Non-Indicating: Indicating, Rejection/Non-Rejection: Non-Rejection, 40 A, 600 V AC/300 V DC, 100/300 kA Interrupt, Class: J, 10 s at 500% Response, Ferrule Terminal, Holder Mount, Cartridge Body Type, Dual Element, Melamine, 1.06 in Dia x 2.38 in L Body Size
Bussmann's UL Class J fuse products extend both our Low-Peak family of products with our LPJ_SP and LPJ_SPI dual-element, time-delay fuses as well as our Limitron line offering fast-acting JKS fuses. The LPJ fuses provide industry leading 300,000 amp interrupting rating at 600Vac RMS Sym and 100kA Vdc while delivering a minimum of 10 seconds of 500 percent rated current ride-through performance which is ideal for sizing of high inrush loads. The LPJ products are available with optional permanent replace fuse indication. These UL Class J products in sizes 1 to 600 amps provide exceptional performance at 600 Vac and 300 Vdc (see spec sheets for specific details) in a compact size rejecting footprint
- Separate overload and short circuit elements provide time delay for sizing of high inrush loads linked with class J current limitation
- Selective co-ordination ratio of 2:1 (within Low-Peak™ fuse family) prevents electrical shutdowns from extending beyond the failed circuit
- Series combination ratings with branch circuit breakers allows broad range of coverage, independent of breaker manufacturer
- 300 kA at 600 VAC, 100 kA at 300 VDC interrupt rating
- 10 s at 500% of rated current response time
- Permanent fuse indication
- True dual element fuses with a minimum 10 second time delay at 500% overload
- Long time delay minimizes needless fuse openings due to temporary overloads and transient surges
- Can often be sized for back up protection against motor burnout from overload or 1 ph if other overload protective devices fail
- High interrupt rating to safely interrupt over currents up to 300 kA
- High degree of current limitation due to the fast speed of response to short circuits
- Faster response to damaging short circuit currents than mechanical over current protective devices
- Reduces let-through thermal and magnetic forces in order to protect low withstand rated components
- Dual element fuses have lower resistance than ordinary fuses so they run cooler
- Lower watts loss reduces power consumption
- Unique dimensions assure that another class of fuse with a lesser voltage rating, interrupt rating or current-limiting ability cannot be substituted
