remarks:
1. The standard function of GC-DB300 is full measurement, with standard protection, 1 switch input, 3 relay outputs (trip and alarm), no display, no communication.
2. Standard protection: Short circuit protection, locked rotor protection, timed overload protection, inverse time overload protection, light load protection, grounding protection, current imbalance protection, long start-up time protection, phase loss protection, process interlocking; Protection, overvoltage protection, undervoltage protection, and phase sequence protection.
3. ② Optional. If the suffix option is not specified, it means that the function is not needed. For example, if only GC-DB300 is specified, it means that only the standard features of GC-DB300 are selected.
4. When selecting, indicate the voltage level, with 380V and 690V options available.
5. When selecting the - K start control function, 5 switch inputs and 4 relay outputs are required
6 GC-DB300-60-D-TQKS-5DI-4DO-C1-AO-380, Indicating that it comes with standard functions, split display, tE protection, self starting due to shaking, 5-way switch input, 4-way relay output, 1-way 485 communication, and 1-way analog output. It needs to be started for control, and a 60A through core transformer with S0E event recording is selected. The line voltage is connected to 380.
