Easily built secondary surge protector adopts a protection circuit combining zinc oxide varistor and dynamic thermal release, which greatly improves the safety and reliability of the low-voltage distribution system.
Anti-vibration pluggable module design, even if the transportation vibration, the impact of the current discharge will not loosen the module, replacement of the module without any tools, simple operation, provides a good user experience. The ingenious design of the large arc shield provides fast heat conduction in low-temperature solder joints and large creepage distance (>10mm) after decoupling, which improves the decoupling sensitivity and reduces the risk of misfire. Local red and green visualization windows and floating switching dry contact remote alarms allow effective monitoring of the surge protector’s operating status.
The series offers a wide range of continuous operating voltages from 60Vac to 1000Vac and various grid system protection modes, including TT, IT and TN.
Secondary surge protectors are typically installed in lightning protection zones LPZ 0B-3 and subsequent zones.
