type 2class IIremote signaling

• 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. Application: • 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. Installation: • 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.
