Combi Tester

MODEL 6050 (LOOP+RCD)
 
 

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.
6050
CE
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.
