WATSG100/4AT

The Schneider WATSG100/4AT is a Surge Protection Device (SPD) designed to protect electrical installations from transient overvoltages, such as those caused by lightning strikes or switching surges. It is part of Schneider Electric's WATS series and offers robust protection for low-voltage electrical systems, with a high surge current capacity.

Parameters: Poles: 4P (4-pole configuration, designed to protect 3-phase systems with neutral) Nominal Discharge Current (In): 100kA (the maximum surge current the SPD can safely discharge) Maximum Discharge Current (Imax): Typically higher than the nominal current, ensuring the device can handle extreme surge events (e.g., up to 200kA or higher depending on the specific model). Protection Class: Type 2 (secondary surge protection, intended for use where primary protection is in place or where moderate surge risks are anticipated) Rated Voltage (Un): 230/400V AC (standard for residential and commercial 3-phase systems) Rated Frequency: 50/60Hz Response Time: < 25ns (rapid response to transient overvoltage events) Voltage Protection Level (Up): Typically ≤ 1.5kV (maximum voltage that can appear across the SPD’s terminals during a surge) Max Continuous Operating Voltage (Uc): 275V (for AC systems) Temperature Range: -40°C to +80°C (wide operational temperature range, suitable for various environmental conditions) Degree of Protection: IP20 (protected against solid objects larger than 12mm) Mounting: DIN rail mounting for easy integration into electrical panels
