Answer Posted / md. obaydur rahman
All the above answers are wrong because we know that for a
constant power rating,
P=V*I
i,e. I=P/V
From the above equation we can see that if the voltage
changes the current is also changed for a constant power
rating i,e. if voltage reduced the device draws more current
to consume its power rating and vice versa.

Can you used moeller lzm1 mccb in a dc system with 125vdc and 20ka short circuit current , beside is it have 24 or 48 volt shunt ? Beside how long current can through from An MCB shunt contacts? (like Z7-AS 24 V)?
In our plant we have installed new MCC with ELR and CBCT which is detecting some leakage current in the system but it leading to some confusion when to check that in which feeder which is drawing current we put off the whole panel itself but still CBCT detecting some leakage current so can anybody ans me , where i am going wrong or how to detect whether its actual leakage or CBCT malfunctioning.
