PTG Type 2 SPD adopts MOV and mechanical thermo disconnect device, which greatly improves the safety and reliability of low-voltage power system.

Easy replacing and anti-vibration by modular releasing and locking design, even if the impact of transportation vibration and current discharge will not lead to the module loose, however, and the replacement of the module is tool free. The ingenious design of Anti-arc technology with large arc extinguisher provides the fast heat conduction by the low-temperature solder joint, and the large creepage distance (> 10 mm) after the disconnection, which greatly improving the tripping sensitivity and reducing the fire risk. The visual status indication of the local red and green window and the remote signaling alarm of the floating switching dry contact effectively indications the working status of the SPD, providing a user-friendly customer maintenance experience.

This series also provides a wide range selections of continuous operating voltage from 60 Vac to 760 Vac, as well as various forms of power system, including TNC, TT, IT and TNS.

PTG Type 2 SPDs are usually installed in LPZ 0_B-2.
