Digital ELCB Tester with Current rating up to 500mA, Auto Ramp,Phase Switch, Reads Disconnection Time, Self-Powered

• Suitable for Use on 230V/50Hz single-phase line (operating voltage: 195~253V);

• Adopts Micro-Processor Chip to maintain high accuracy, reliability 
and stability; 

• Wiring Check: three –LED indication 
When P-E and P-N green LED are on and red LED is off, the wiring is correct; otherwise it indicates wrong wiring(reverse P and N or bad grounding); 

• Phase Angle Selection: The tests can be performed at positive 0 or negative 180 phase angle. 

• Over-Load Indication: “OL mS” shows when trip time exceeds Max. test time 

• Auto Data Hold: The test results will be maintained for a while after the tests finishes. 

• Auto Ramp Test: Test trip current and trip time simultaneously
• Power-Off Warning Indication: The buzzer alarms after operating 
for 3minutes; 

• Power Save and Environment-Friendly: Powered directly by 
tested circuit (Power 230V/50Hz) , no need to use battery; 

• Fused Protection 

• Double or Reinforced Insulation for safe design.
• Trip Current Setting: 10 / 20 / 30 / 100 / 300 / 500mA
• Confirms to IEC 61010-1 CAT III 300V, IEC 61557-1,5 and IEC 61010-2-31
