ABB S203-C100 3-Pole 100A 6kA Type C MCB

The ABB S203-C100 is a 3-pole 100A Type C miniature circuit breaker with 6kA breaking capacity from the ABB S200 series. Rated for 400V AC operation and built to withstand ambient temperatures from -25ยฐC to +55ยฐC, it is well suited for three-phase circuit protection in UAE distribution boards where reliable performance in high-heat environments is essential.

Key Features

  • 3-pole 100A Type C MCB for three-phase distribution circuit protection
  • 6kA breaking capacity at 400V AC, with a rated conditional short-circuit current of 20kA at 400V
  • Type C tripping characteristic suitable for circuits with moderate inrush currents
  • Rated for continuous operation across a wide -25ยฐC to +55ยฐC ambient temperature range, suitable for UAE climate conditions
  • Genuine ABB S200 series quality โ€” 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.
  • What does the 6kA breaking capacity mean?
    6kA is the maximum fault current this MCB can safely interrupt without damage. It should be equal to or higher than the prospective fault current at its installation point in the 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 โ€” 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 โ€” it is not a DIY consumer product.
