Single-pole and multi-pole surge arresters - Class III / (D)
ISPRO D(R) 10, ISPRO DM(R) (2+0), ISPRO DMG(R) (2+0)
The ISPRO D, DM and DMG series of overvoltage surge protective devices has been developed to protect against indirect lightning discharges and induced voltages. It is intended to provide protection in zones 2 - 3 as per IEC 62305.
The plug-in module / base design facilitate replacement of a failed module without the need to remove system wiring etc.
- ISPRO D consists of a high performance varistor block with thermal disconnection device.
- ISPRO DM consists of two performance varistor blocks with thermal disconnection devices configured to provide multi-pole protection to L-PE and N-PE in one enclosure.
- ISPRO DMG consists of two performance varistor blocks with thermal disconnection devices and galvanic isolation N to PE for TT single phase networks.
- Class III / (D)
- Surge discharge ratings Uoc/Isc: 10 kV / 5 kA per pole (1.2/50, 8/20)
- Housing: modular
