  • Global patented thermal disconnector design with arc extinguishing device, fail-safe & self-protected, quick thermal response and perfect circuit cutoff function
  • Visual fault indication and optional remote signal contact (50mA, 12Vdc)
  • Wide operating temperature: -40℃~85℃
  • Type 1CA design & compact size, can be used individually or in combination for OEM customer
  • Meet both standards for ANSI/UL 1449 4th and IEC 61643-11: 2011

TPMOV Applications

  • Built-in surge protection of electronic equipment
  • Surge protection devices
  • AC/DC distribution
  • Computer and data technology
  • Power supply
  • Telecommunication
  • Measurement and control system

At 415Vac temporary overvoltage, our SMTMOV with TAPE technology cuts itself off this abnormal condition and stays safe

From TPMOV to Enclosure-less Panel SPD – Great Option for SPD Manufacturer

Besides offering TPMOV as a component to manufacturers, Prosurge launched a semi-completed surge protection device called Enclosure-less SPD. We have completed the circuit design and assembly of the electronic components of a panel type SPD and have this assembly UL listed. In this case, we handle the complicated and time-consuming jobs in manufacturing a panel type surge protection device so that customers can maufactuer their UL listed panel type SPD at mimum cost and time.
