Finger-Proof MCC
Finger-Proof MCC
(OP)
Hi to all.
I want to make some changes in MCC in order to make them water-proof and ensure inside protection IP20 and use padlocks in automatic circuit breakers. I use circuit breakers SIEMENS 3RV1 series. Can you give some help ?

Motor controllers with type 12 enclosures are often used outdoors here in the U.S. just a matter that the watertightness depends on gaskets unlike type 3R and boht enclosure types do need water drains. For instance, most meter sockets are type 3R which keeps falling rain out and most driving rain out enough and lets water out enough that driving rain is not a problem. There are other ways for water to get in such as through a service conduit that originates at a higher elevation and is transmitting water. Conduit seals do fail under the influence of constant water pressure.
Also remember that both concentric stranded and compact stranded wires acts as a poor excuse for a water hose unless the strands have a blocking compound such as Pirelli Strandseal(R).
