Description
Features
UL1449 4th ed. 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
• UL1449 4th approved
• 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
Environmental Specifications
UL1449 4th ed. 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.
Type 1 SPD
VOLTAGE:
120/208 VRMS, 3 WIRE & GROUND
SINGLE PHASE, 50/60HZ, MCOV 150V
VOLTAGE PROTECTION RATING – VPR
L-L 1200V, L-G 1200
NOMINAL DISCHARGE CURRENT (In) 10 KA
SHORT CIRCUIT CURRENT RATING

TYPE 3R ENCLOSURE
End of Life Failure Mode
While in overvoltage induced thermal runaway, apply 7 KA at operating voltage. 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.
