Class J Time Delay Fuses have a faster response to short-circuit currents than other overcurrent protective devices
- Dual-Element, Time-Delay - 10 seconds (minimum) at 500% rated current
- IR: 200kA RMS Sym. 300kA RMS Sym. (self certified)
- Long time-delay minimizes needless fuse openings due to temporary overloads
- 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 300kA
- High degree of current limitation due to the fast speed-of-response to short-circuits
- Faster response to short-circuit currents than other overcurrent protective devices
- Reduces let-through 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 so 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
- UL Listed, Class J
- CSA Certified HRCI-J 200,000 AIR
- Class J per CSA 22.2 No. 248.8, Class 1422-02
