ABB ELCB/RCCB FH202 AC-40/0.1 2-Pole 40A 100mA
The ABB FH202 AC-40/0.1 is a 2-pole RCCB rated 40A with 100mA sensitivity for earth fault and fire protection on single-phase incoming circuits in UAE residential and commercial distribution boards. The 100mA sensitivity provides the appropriate level of protection for upstream fire-protection ELCB applications on 2-pole boards.
Key Features
- 40A 2-pole RCCB for single-phase incoming protection
- 100mA sensitivity for fire-protection upstream duty
- Type AC for sinusoidal AC residual currents
- DIN rail mounting for DB installation
- Genuine ABB FH200 series quality

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 100mA sensitivity rating mean?
100mA RCCBs are sized for fire and equipment protection on larger circuits and sub-mains, not personal shock protection — that requires a 30mA device. A 100mA unit is a common choice as a main incomer or sub-distribution protection device upstream of 30mA final-circuit RCDs.
-
How many poles do I need?
A 2-pole (2P) RCCB switches live and neutral on a single-phase circuit.
-
Can this be used alongside MCBs in the same board?
Yes. This RCCB is typically installed upstream of the MCBs it protects, on the same DIN rail, so a leakage fault trips the RCCB while overloads/short circuits are still cleared by the individual MCBs.
-
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.
