Surge suppressor with thermal protection designed to open in the event of overheating due to an abnormal over-voltage or temporary over voltage (TOV) and will interrupt any abnormal current that may be encountered.
Ø ETL approved as per UL1449-3rd
Ø In compliance with UL1449 3rd with Interrupt current 100KArms
Ø Type 4 SPD for Type 2 application
Ø High surge current capability Imax 50kA 8/20.
Ø Quick thermal response and perfect circuit cutoff function due to special disconnector design with internal arc extinguishing device (Patent).
Ø When MTMOVs are disconnected from the circuit.
1) Tab can be viewed through top hole of plastic housing.
2) Top pin as monitor terminal
Application in the AC mains, service entrance, and heavy industrial etc.
