Features Superior Surge Protection: With a Uc of 420V and Imax of 60KA, this 3P Surge Protective Device Module effectively limits transient overvoltage amplitudes, protecting your power equipment from surge overvoltage. Reliable Performance: Operating in an ambient temperature range of -40°C to +80°C, this Surge Arrester Device quickly conducts surge overvoltage to the earth, ensuring the normal operation of the grid and safeguarding electrical components. Quick Return to Normal: After the surge voltage passes through, the device promptly reverts to a high resistance state, preventing any disruption to the grid's normal operation. Versatile Usage: Designed for 3 phase and 4 wire systems, this Surge Protective Device is ideal for use in homes, farms, and office buildings, providing essential protection in various scenarios. Safe and Durable Material: Constructed from flame retardant PC material, this Voltage Surge Arrester Device ensures safety and longevity in its performance, offering peace of mind for your electrical systems.
