LOOP+RCD
Product Overview
- Kew Combitester provides the ultimate in Microprocessor technology offering Loop and RCD tests with a comprehensive memory and downloading test results.
- LOOP Impedance 200/2000Ω range measurement is carried out using a test current of 15mA. This current will not trip RCD’s rated at 30mA or greater.
- High resolution for low Loop Impedance (resolution of 0.01Ω) on 20Ω range.
- Direct reading of Prospective Short Circuit Current (PSC) and earth fault current.
- RCD tests at 0 and 180 degree phase angle switch permit quick tests and consistent readings.
- Test of a large kind of RCD's Standard, Selective, AC and A (DC sensitive breakers).
- Constant current source circuitry ensures that a fluctuating mains voltage does not affect the accuracy of readings.
- RCD Ramp test in order to indicate the actual tripping current of RCD.
- Contact Voltage Reading (UC). with two selectable contact voltage limits (50 and 25V).
- Visual indication of correct wiring status and automatic lock-out if test resistors overheats.
- Designed to IEC 61010-1, IEC 61557 and high protection degree IP54.
- The stored data can be transferred to PC via Optical Adapter Model 8212-RS232C and 8212-USB.
