PCB or SPD panel-used Surge Protector
TUV mark TMOV
Product Picture
● Smart TMOV is a surge suppressor applied in PCB or SPD panel to absorb the surge and interrupt any abnormal current that may be encountered.
● Smart TMOV is designed to safety disconnect from their power source perfect thermal protection, and will open in the event of overheating due to an abnormal over-voltage or temporary over voltage(TOV).
● Special damper design, will not fire in case of maximum power frequency over-voltage.
Features:
● New patent, quick thermal response and perfect circuit cutoff function due to double thermal
disconnections design,Aside thermal disconnection can work and disconnect the circuit when
may be encountered a small leakage impulse current; B side thermal disconnection can work
and disconnect the circuit when may be encountered a large impulse current.
● Wide operating temperature range and high reliability.
● No need of back-up fuse
● Discharge capacity (10kA-40kA), low leakage current.
● Floating remote signaling contact (50mA12Vdc) for fault indication.
● Application in the AC mains,service entrance,and heavy industrial etc.
