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
• 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
• UL Listed
