PSM SAFEGROUND DIN – rail device for monitoring the earthing system from within the actual surge protection device. SAFEGROUND technology is based on the loop impedance monitoring sending current pulses to check the status of the grounding system and provide information regarding the proper wiring of the device and the existence of an adequate path to ground for the SPD itself to protect effectively. Confirms the device is properly installed and how effective the surge protection is Indication of the status of the earth loop via multi-state LEDs High discharge capacity with an 8/20 ¼ waveform. Imax: 40 kA SERIES PSM SAFEGROUND series (8/20 ¼) L-N (IMAX) 40kA MAXIMUM VOLTS L-N (Uc) 275 V VOLTAGE PROTECTION (Up) ≤ 1.3kV NUMBER OF POLES 4 CONFIGURATION 3ph+N WIDTH IN 18 (MM) 4
