​

Main Host Volume

• 360×260×170mm

Operating Environment

• Temperature: -20 °C to +50 °C

• Relative humidity: ≤90%

• The instrument automatically recognizes the opening and closing status of the fracture to prevent misoperation.

• Independent 12 fracture ports can detect and prompt the connection status of the fracture ports, which is convenient for users to check the wiring.

• 100 sets of test results can be stored in the machine.

• Large-screen LCD (320×240) display, advanced gray screen, no reflection or black screen in the sun, graphic menu operation prompts, humanized menu interface, easy to operate.

• The instrument has a powerful graphic analysis function, which displays waveforms and measurement processing data on the same screen, making the test process more intuitive.

• The machine has a delay protection function, and the coil voltage can be automatically cut off after the circuit breaker is activated, protecting both the circuit breaker and testing equipment. An independent and special opening and closing control unit can be used for closing or opening tests.

• If one of the control loops is broken, it will not affect the use.

• This instrument can carry out electric and manual opening and closing tests.

• It can conduct high and low voltage experiments and automatically find the lowest opening or closing voltage.

• The reclosing test can measure parameters such as closing, opening, and closing.

• It can measure parameters of vacuum contactors (single coil).

• The circuit breaker aging test (life test) can be completed automatically.
