Characteristics
Reset button :
Signals add-on block tripping and must be reset before switching on the
installation.
Test button for RCD function :
Checks the electrical operating of the MCCB / Add-on block
association.
Mechanical test button :
Checks the mechanical operating of the MCCB / Add-on block
association.

Remote tripping and advanced warning (50% I

n
) signaling thanks to
these contacts:
When associated with MCCB, the add-on block provides an earth fault
protection and protects against electrical shocks by direct or indirect
contact.
The add-on blocks are protected against nuisance tripping caused by
transient voltages. It’s able to detect sinusoidal alternating currents and
residual pulsating direct currents ( A type ). It also avoids miss
tripping (HI type - High Immunity).
