DELIXI · Self-resetting voltage protector
Product overview
The DELIXI DZ47vGQF automatically disconnects and restores a circuit in response to the documented overvoltage and undervoltage conditions. The reference separates 1P+N and 3P+N versions and distinguishes top-incoming GQF from bottom-incoming GQR wiring.

The 100 A selection is listed for 3P+N only. Confirm GQF top-incoming wiring, the neutral/phase terminal arrangement and the exact current rating. GQR reverse-feed versions require their own complete code; do not reverse the feed direction by assumption.
Typical applications
- Voltage-supervision protection in matched single-phase distribution circuits
- Matched three-phase circuits using the documented 3P+N version
