Type 7P.01 surge arresters, SPD Type 1 + 2, varistor + GDT single pole usable in single phase or three phase applications (230/400 V AC).
Combination of varistor and gas spark gap, with visual signaling and with remote contact of the state of the varistor/GDT. Upside down mount technology.
Replaceable modules.
Features include:
- SPD suitable for low voltage systems for protection against overvoltages caused by direct discharges, induced and operating overvoltages
- To be installed on the border between zones LPZ 0 and LPZ 1
- Combination of high-performance varistors and gas spark gaps (GDT) which ensure:
• high discharge currents
• high insulation resistance which eliminates the
leakage current
• absence of subsequent follow-on current
- Extremely low residual voltage
- Replaceable modules
- Upside down mount technology (thanks to the double marking of the terminals and the new restraint system of the replaceable module that allows its reversal)
- Visual indicator of the varistor status: functional/to be replaced
- Double screw terminal
- Signaling with remote contact of the varistor status: presence, functioning, to be replaced
- Connector (07P.01) included in the package
- In accordance with EN 61 643-11
- 35 mm rail (EN 60715) mounting, 36 mm per pole
