FAQ

1. Does it support DC earth leakage protection?
This series is for AC residual current protection; DC systems require dedicated DC earth leakage protection devices.
2. Must the neutral wire pass through the transformer during installation?
For 1P+N and 3P+N models, the neutral wire must pass through the transformer together with the phase conductors; otherwise, earth leakage protection will be ineffective.
3. Is it suitable for TT and TN systems?
Suitable for TT, TN-C-S, and TN-S systems; refer to the product manual for specific wiring methods.
4. Does it support remote tripping?
Standard models do not; remote electrical tripping can be achieved by customizing a shunt trip accessory.
