ABB A2N 250 TMF 200-2000 3-Pole MCCB
The ABB A2N 250 TMF 200-2000 is a fixed three-pole moulded case circuit breaker from the ABB Formula series, rated at 200A with a thermomagnetic (TMF) release for fixed thermal and magnetic protection settings. Its high current rating and N-rated short-circuit performance make it well suited to main incomer and large feeder protection in UAE commercial and industrial distribution boards.
Key Features
- 3-pole 200A moulded case circuit breaker with fixed thermomagnetic (TMF) release for dependable overload and short-circuit protection.
- 36kA ultimate breaking capacity (Icu) and 18kA service breaking capacity (Ics) at 415V AC, providing strong fault-level headroom for high-current UAE distribution panels.
- N short-circuit performance level suited to higher-duty and main incomer applications.
- Front terminal connection for straightforward installation and wiring access in panel builds.
- Genuine ABB quality — manufacturer tested and rated for 10,000 mechanical operating cycles.

FAQ
-
What's the difference between an MCB and an MCCB?
An MCB (miniature circuit breaker) is typically rated up to 100A with a fixed, non-adjustable trip and lower breaking capacity, used for final circuits. An MCCB (moulded case circuit breaker) is built for higher currents and fault levels, and is used for main incomers, sub-mains, and feeder protection where an MCB's rating or breaking capacity would be insufficient.
-
When do I need an MCCB instead of an MCB?
Use an MCCB where the prospective fault current or load current exceeds what an MCB is rated to handle safely — typically at the main incomer or major sub-main level of a commercial or industrial distribution board.
-
Does this MCCB have an adjustable trip setting?
Check the specific trip unit type in the Technical Specifications table above — thermal-magnetic MCCBs may have a fixed or adjustable trip range depending on the model; an electronic trip unit typically offers configurable protection curves.
-
Can I install this myself?
No. MCCBs are installed in distribution boards and panels by a licensed electrician, in line with UAE wiring regulations.
