Circuit Breakers RCBO
are available with a breaking capacity of
10kA to IEC601009 The RCBO are calibrated to 40
and can be supplied with 50 ambient calibration.
FTCP RCBO Field Fitted Residual current units
Any standard 1P+N FTMC MCB 10kA & 6kA, can be residual current unit to create an RCBO.
To obtain a true reading of insulation testing (500V) with RCBO
installed, disconnect the RCBO functional earth lead. (this will
enable its electronic circuit to be isolated from earth), With this
lead disconnected the insulation resistance can then be measured
to the protected earth with the phase and neutral connected together
(as per BS7671) N.B. Reconnect earth wire after test.
