FAQ
-
What's the difference between an MCB and an RCCB/RCD?
An MCB protects circuits and wiring against overload and short-circuit current. An RCCB like this one protects against earth leakage by monitoring current imbalance and disconnecting the circuit — the two are complementary and are normally installed together in a distribution board.
-
What does the 30mA sensitivity rating mean?
30mA RCCBs are sized for personnel/shock protection on final circuits — the standard choice for socket outlets and circuits people directly touch.
-
Is this a 4-pole ELCB or RCCB?
Yes — RCCB and ELCB are two names for the same type of device. This model is a 4-pole unit rated 63A with 30mA sensitivity, switching all three phases plus neutral.
-
Does it mount on DIN rail?
Yes, it's designed for standard DIN rail mounting in distribution boards and panels alongside other DIN-rail devices.
-
Can I install this myself?
No. RCCBs are wired into a live distribution board and must be installed by a licensed electrician in line with UAE wiring regulations.
