ABB S203-C32 3-Pole 32A 6kA Type C MCB
The ABB S203-C32 is a 3-pole, 32A Type C miniature circuit breaker with 6kA breaking capacity from the ABB System pro M compact S200 series. Combining a delayed thermal tripping mechanism for overload protection with an electromechanical mechanism for short circuit protection, it is current limiting and suited to three-phase circuit protection across residential, commercial and industrial UAE installations.
Key Features
- 3-pole 32A Type C MCB for three-phase circuit protection in distribution boards
- 6kA breaking capacity matching standard UAE commercial and industrial fault levels
- Type C tripping characteristic suitable for resistive and lightly inductive loads
- Bottom-fitting auxiliary contact compatibility, saving up to 50% panel space compared to side-mounted accessories
- Genuine ABB S200 series quality — consistent performance and reliability

FAQ
-
What's the difference between an MCB and an RCCB/RCD?
An MCB (miniature circuit breaker) protects wiring and connected equipment against overload and short-circuit current. An RCCB/RCD protects against earth leakage by monitoring current imbalance. The two are complementary and are normally installed together in a distribution board.
-
How many poles do I need?
A 3-pole (3P) breaker switches all three phases on a three-phase circuit without a switched neutral.
-
Is this MCB compatible with other ABB DIN-rail distribution boards?
Yes — it's a standard DIN-rail (EN 60715) mounted breaker and clips directly into ABB's modular consumer units and distribution boards alongside other ABB DIN-rail devices.
-
Can I install this myself?
No. This is a distribution board component and must be installed and connected by a licensed electrician in accordance with UAE wiring regulations — it is not a DIY consumer product.
