CONDITIONS FOR ASSEMBLYThe annex G of the EN 61009-1 standard says:- It shall not be possible to assemble an MCB of

a given rated current with an add-on RCD unitof a lower maximum current.

- It shall not be possible to assemble an add-onRCD with an MCB having no provision forswitching the associated neutral.

To comply with these conditions we have devisedan add-on RCD miss-insertion system which avoidsincorrect assembly.

The correct assembly shall be done as follows:

TOGGLETo switch the add-on RCD ON or OFF. The toggle isoverlapped with the one of the coupled MCB andboth can be switched ON at the same time.

TAMPER PROOF SEALING SYSTEMTo seal the combination MCB/RCD once theassembly is finished. Any manipulation after sealingthe combined unit, will result in visible damage.

TERMINAL COVERSUnlosable terminal covers for the MCB bottom terminalsas well as for the RCD terminals are provided.

MOBILE CONNECTIONFor an easy and quick assembly theconnection wires are two position.

ALL CABLES MUST BE CONNECTED TO THE RCBOIn order to protect the RCD in the proper way, it isrecommended to feed the combined unit (MCB/RCD)by the MCB (top terminals), in such a way the MCBprovides back up protection to the RCD.

All conductors, phases and neutral, that constitutethe power of the installation to be protected mustbe connected to the MCB/RCD combination.

ACCESS TO THE MECHANISM FOR EXTENSIONSIt is possible to add any auxiliary contact, shunt trip,undervoltage release or motor operator on the lefthand side, following the stack on configuration ofthe extensions in page xxx.

Influence of air ambienttemperature on the ratedcurrentInfluence of temperature on RCCB

The maximum value of the current which can flowthrough an RCCB depends of the nominal currentas well as the ambient air temperature. Theprotective device placed up-stream of the RCCBmust ensure the disconnection at the values inthe following table:

The above mentioned values are for devices in thefree air. For devices installed with other modulardevices in the same switchboard, a correctioncoefficient (K) shall be applied in relation to thenumber of main circuits in the installation (EN 60439-1):

Calculation exampleWithin a distribution panel consisting in eight MCB2PC16 and with an operating ambient temperatureof 45°C, which is the highest temperature the MCBcan operate at without unwanted tripping.

CalculationThe correction factor K=0.7, for use in an eightcircuit installation: 16A x 0.7= 11.2AAs the MCB is working at 45°C another factor isapplied (90% = 0.9):At 45°C = In at 30°C x 0.9 = 11.2A x 0.9 = 10.1A

Influence of temperature on RCBO’s Series DP & DPE

The thermal calibration of the RCBO was carriedout at an ambient temperature of 30°C. Ambienttemperatures different from 30°C influence thebimetal and this results in earlier or later thermaltripping.

Tripping current as afunction of the frequencyAll the RCD’s are designed to work at frequencies of50-60 Hz, therefore to work at different values, wemust consider the variation of the tripping sensitivityaccording to the tables below. It should betaken into consideration that there is a no trippingrisk when pushing the test-button, due to the factthat such action is made by means of a internalresistor with a fixed value.

Protection of RCCB’s Series FPRCCB’s are not overcurrent protected. Therefore wedon’t need to consider both protection againstshort-circuits and overloads.

Protection against short-circuitsCOORDINATION OF RCCB’s WITH MCB’s ORFUSES, BACK-UP PROTECTION

RCCB’s protected with a SCPD have to be able towithstand, without damage, short-circuit currentsup to its rated conditional short-circuit capacity. The SCPD has to be carefully selected, since theassociation of this device with the RCCB isinterrupting the short-circuit of the installation.

The value of the presumed short-circuit current atthe point where the RCCB is installed shall belower than the values of the following table:

The RCCB and the protective device must beinstalled in the same switchboard, paying specialattention to the connection between these twodevices since if the SCPD is installed downstreamof the RCCB such a connection must be short-circuit protected.SCPD = Short-Circuit Protective Device.
