Main Technical Parameters (Summary)
The KGQ2 series covers 100A–1600A ratings in 3P / 4P versions. Typical systems are AC400V.
Utilization categories commonly include AC-33B / AC-31. Short-circuit and withstand capacities vary by rating;
refer to the datasheet for precise values. Transfer time and endurance are designed for frequent switching,
with optional auxiliary contacts, remote signaling, and fire-control terminals depending on configuration.
Wiring & Operation Modes
- Automatic changeover (grid ↔ standby / generator)
- Emergency manual operation; optional remote control
- Electrical & mechanical interlock for safe transfer
- Fire-control / dry contact signal terminals (if equipped)
Follow the official wiring diagrams in the datasheet during installation.

FAQ
What is the difference between KGQ2 and KGLD?
KGQ2 is an MCCB-type automatic changeover switch with compact structure, while KGLD is an isolating ATS with higher dielectric withstand and larger current coverage.
Does KGQ2 support generator transfer?
Yes. KGQ2 supports grid–generator transfer with automatic or manual operation as configured.
Is remote control available?
Yes. Optional remote control and status signal outputs are available via accessories or controller modules.
