CIRPROTECSurge Protection Devices for MDB

PSM4-40/400 SG

  • PRODUCT INFO

  • SAFEGROUND is the series of DIN rail devices for monitoring the grounding system from within the actual surge protection device. Type 2 surge protection according to IEC 61643-11. SAFEGROUND technology is based on the loop impedance monitoring sending current pulses in order to check the status of the grounding system. This provides information about the proper wiring of the device, as well as about the existence of an adequate path to ground for the SPD itself to protect effectively.
