SPECIFICATION (as per one set):

1. Power supply: 3-phase 4-wire and power is controlled by on/off buttons, with leakage protection. Also, emergency button is available.

2. A analog AC voltmeter (0~450V) is used for grid voltage measurement and a AC ammeter (0~5A) is used for load current measurement.

3. Modular for easy operating.

4. All the components, such as switch, ganged switch, sing/three-phase watt meter, fluorescent lamp, etc. are connected to the terminal blocks for easy and technical connection to avoid damage.

5. Tools: wire stripper, sharp nose pliers, diagonal cutting pliers, phillips screwdriver, slotted screwdriver etc.
