Pro Electricians Digital RCD Tester Cat III

DT904 is a CE certified Cat 3 digital RCD Tester designed for the professional, it tests for correct operation of RCDs (Residual Current Devices). A RCD) or a residual current circuit breaker (RCCB) commonly know as a safety switch is designed to isolate power when it detects an in-balance commonly of 30 mA (milliamps) between the active and neutral conductor. These in-balances are commonly caused by current leakage through earth. This leakage can be caused via a faulty appliance or through the body of a person accidentally touching an energized piece of equipment. RCD/RCCB’s are designed to disconnect power to the circuit when a difference of 30mA is detected. This disconnection or tripping of these breakers should happen without due delay, if the RCB/RCCB takes to long to trip the results could be fatal.

It is a requirement to test and check for the correct operation of RCD, and this meter is designed to do exactly that. This meter is fully programmable making it extremely easy to use and it will also test the latest delay action breakers as well as being able to check for correct wiring status very quickly

• 2000ms readout for testing latest delay action breakers
• Fully programmed operation
• Accurate digital read out of tipping time
• Two neon lamps give quick check for correct wiring
• Operates from mains supply. No need for batteries
  
• Compact, light weight and simple to operate
• Zero cross circuitry permits testing at 0°and 180°portion of sine wave at these two tests minimum(best) and Maximum (worst) trip times will be displayed 
• Data hold function to freeze the digital trip time display allows for easy readout and eliminates the possibility of reading error
