Couldn't load pickup availability
The ABB SH203-C63 (2CDS213001R0634) is a 3P 63 A C-curve miniature circuit breaker with 6 kA breaking capacity. It protects cables and connected equipment against overload and short circuit in three-phase circuits, motors and sub-distribution feeders, and clips onto a standard 35 mm DIN rail in apartment, villa, commercial and industrial distribution boards.
Key features
- C-curve characteristic suited to general loads such as lighting, sockets, air conditioners and small motors (magnetic trip at 5–10 × In)
- 3P construction for three-phase circuits, motors and sub-distribution feeders
- Breaking capacity 6 kA for safe disconnection of short-circuit currents
- Clear ON/OFF handle with contact position indication for safe isolation
- Quick clip-on mounting on 35 mm DIN rail, compatible with standard pin/fork busbars
- Compact modular width for neat, standardised distribution boards

Selection and installation tips
Match the breaker rating to the cable cross-section (typically 10 A for 1.5 mm² lighting, 16–20 A for 2.5 mm² sockets, 25–32 A for 4–6 mm² air-conditioner lines), choose the curve according to the inrush current of the load, and make sure the breaking capacity exceeds the prospective short-circuit current at the board. Add an RCCB or use an RCBO for earth-leakage protection.
Frequently asked questions
What is the ABB SH203-C63 used for?
It is a 3P 63 A C-curve MCB used to protect three-phase circuits, motors and sub-distribution feeders against overload and short circuit.
Does an MCB protect against electric shock?
No. An MCB protects cables against overload and short circuit only. For protection of people against earth leakage use a 30 mA RCCB upstream or an RCBO.
Which MCB rating do I need for an air conditioner?
As a guide, 1.5–2.25 HP split units usually use a 16–20 A C-curve MCB, 3 HP units 25 A and 4–5 HP units 32 A, always matched to the cable size recommended by the manufacturer.
