Test Instrument for the Suppression of RCCB Tripping and for Tripping Tests of DC Components in AC-DC Sensitive RCCBs
■Loop Resistance Measuring Mode with the PROF/TEST... with Suppression of RCCB Tripping
▲The PRO/TTEST DC-丨 I test instrument allows for the measurement of loop resistance in TN systems with RCCBs (10/30/100/300/5CX) mA nominal residual current) without DC sensitive components.
▲The test instrument generates a DC residual current which saturates the magnetic circuit of the RCCB.
▲The PROHTCST OIOOS/S-II.PRO/TTEST 2 or PROHTEST-C superimposes a measuring current which demonstrates only hatf-waves of like polarity. The RCCB cannot detect this measuring current and can thus no longer be tripped during measurement.
