Protection Devices
Surge protection products must be versatile to ensure safe and error-free protection. WAGO's overvoltage protection products ensure reliable protection of electrical equipment and electronic systems against high voltages.
Product Family Overview
Early Ground Fault Detection
Increasing Availability via Improved and Preventive Maintenance
According to the IEC 60204-1 standard, measures must be taken to reduce the probability of malfunctions due to insulation faults/ground faults in a control circuit. A common option is connecting 0 V to the ground potential in the control circuit, in combination with an upstream fuse. With the new ground resistance signaling module, WAGO offers the possibility of detecting not only the 0 V grounding, but also the full and automatic undershooting of a non-adjustable, unbalanced insulation resistance between +24 V or 0 V of the supply voltage and ground. An integrated potential-free contact can be used to signal the Iso OK status to a controller. Additionally, on-module LEDs clearly indicate the insulation fault to the operator.
Compared to mechanical ground conductor disconnect terminal blocks, maintenance is considerably simplified. With this new module, a permanent insulation resistance test can now be performed every three months instead of the standard manual ground fault test. Early detection of imminent ground faults enables improved preventive maintenance, ensuring increased system uptime. A slide switch allows the user to select the grounded/ ungrounded control circuit operating mode. However, the module does not meet the requirements for insulation monitoring devices according to IEC 61557-8.
