Description
Features
Intertek certified to UL 1449 4th edition surge suppressor with thermal protection designed to open in the event of over heating due to an abnormal over-voltage or temporary overvoltage (TOV) and will interrupt any abnormal current that may be encountered.
• Compact Size
• Intertek tested and approved to ANSI / UL 1449 4th edition
• Quick thermal response and perfect circuit cutoff function due to special thermal disconnector design with intemal arc extinguishing device (Patent)
• Wide operating temperature range and high reliability
• Low leakage current
• Application in the AC mains, service entrance, and heavy industrial etc
• SCCR up to 100 KAtms without external fuse or CB
• Fire Proof and explosion proof polycarbonate glass-fiber reinforced enclosure with matching mounting connector
• Sealed unit except for mounting connector wiring opening
• For less inductance, #10 AWG tinned copper wire
• MCOV 150

End of Life Failure Mode
While in overvoltage induced thermal runaway, apply 7 KA at 120 VAC. Surge arrester must fail safe without faulting the AC line. No arcing allowed.
Surge arrester fails safe– surge element punctures, safety fuse opens, LED turns off, no fire, slight puff of smoke out connector wiring opening. AC line not faulted. No arcing.
