RCD test instrument
Measuring instrument for testing the characteristics of RCCBs.
In particular, this involves the measurement of touch voltage, breaking time and breaking current for type A, AC, and S RCCBs, as well as type F mixed frequency RCDs as of recently.
• Digital display, backlit color OLED display
• LED for measurement point illumination
• Patented test probe retainer
• Compact and rugged – for service calls under harsh conditions and laboratory use
Testing of residual current devices (RCCBs)
• Measurement of touch voltage without tripping the RCCB. Touch voltage is measured with reference to nominal residual current using ⅓ of the nominal residual current value.
• Tripping test with nominal residual current, measurement of time to trip
Special tests for systems and RCDs
• Testing of systems and RCDs with rising residual current including indication of tripping current
• Testing of RCDs, I?N = 10, 30, 100, 300 und 500 mA
• Testing of RCCBs with ½ N, 1?N, 2?N, 5?N up to100 mA nominal current
• Testing of RCDs with half-waves (pulsating direct current) for determining time to trip and tripping current
