Χαρακτηριστικά:
• Low price surge protection device (SPD), Type 2 or Class II test level, selectable in nominal discharge current 10kA with max. discharge current of 20kA accordingly.
• Surge Protection Device for transient electrical over-voltages.
• DIN rail mounting, easy installation, compact size, and good performance.
• Class 2 SPD for typical waveforms of 8/20 μs.
• Best surge protector for your power supply system with rated voltage of 400V AC 50Hz/60Hz.
• The SPD is designed in accordance with IEC Class II.
Εφαρμογή:
• They ensure protection against overvoltage conditions.
• For the protection of low voltage distribution systems against direct lightning strike into the overhead power supply line or external lightning protection system (IEC 62305).
• They are suitable for installation in secondary boards and in terminal equipment.
Εγκατάσταση:
• The line of surge arresters includes a full range of compact protectors for installation on DIN rail
• When the fault indication window turns from green to red please replace the cartridge as soon as possible
• After the installation is complete, check that the protection unit is plug in place, close the automatic circuit breaker (fuse) switch, check the working status is normal.
