2CDS253001R0044 ABB SH203-C4 MCB 3P 4A C Curve 6kA DIN Rail

The ABB S203-C4 (article 2CDS253001R0044) is a 3-pole miniature circuit breaker from the S200 System pro M compact range, rated at 4 A with a C tripping characteristic and a 6 kA AC breaking capacity. It combines a delayed thermal tripping mechanism for overload protection with an electromechanical tripping mechanism for short-circuit disconnection. Suitable for residential, commercial, and industrial installations.

Technical specifications:

• Series: S203-C4 (S200 System pro M compact)
• ABB article number: 2CDS253001R0044
• EAN: 4016779523462
• Poles: 3P
• Rated current: 4 A
• Tripping characteristic: C
• Breaking capacity: 6 kA (AC)
• Rated voltage: 230/400 V AC
• Standards: IEC/EN 60898-1, IEC/EN 60947-2, UL1077

Features and benefits:

• Current limiting design reduces energy let-through during fault events
• Thermal tripping guards against sustained overload currents without nuisance tripping
• Electromechanical tripping delivers fast disconnection under short-circuit conditions
• Accepts bottom-fitting auxiliary contacts, saving up to 50% panel space compared to side-mounted accessories
