Low-Peak®
Dual-Element Time-Delay Fuses |
 |
| Class J - 600 Volt 0-60 Amps |
LPJ |
- 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 single-phasing if other overload protective devices fail
- High interrupting rating to safely interrupt overcurrents up to
300,000 amperes
- High degree of current limitation due to the fast speed-of-response
to short-circuits
- Faster response to damaging short-circuit currents than mechanical
overcurrent protective devices
- Reduces let-thru thermal and magnetic forces in order to protect low
withstand rated components
- Proper sizing provides "no damage" Type "2"
coordinated protection for NEMA and IEC motor control in accordance with IEC Standard
947-4-1
- Dual-element fuses have lower resistance than ordinary fuses, hence
they run cooler
- Lower watts loss reduces power consumption
- Unique dimensions assure that another class of fuse with a lesser
voltage rating, interrupting rating or current limiting ability cannot be substituted
- Space-saving package for equipment down sizing
