2CDS253001R0504 ABB SH203-C50 MCB 3P 50A C Curve 6kA DIN Rail

The ABB S203-C50 (article 2CDS253001R0504) is a 3-pole miniature circuit breaker from the System pro M compact S200 range, rated at 50 A with a C tripping characteristic. It provides current-limiting protection with a 6 kA AC breaking capacity at 230/400 V, using delayed thermal tripping for sustained overloads and a separate electromechanical mechanism for short-circuit events.

Technical specifications:

• Series: S200 (S203-C50)
• ABB article number: 2CDS253001R0504
• EAN: 4016779551069
• Poles: 3P
• Rated current: 50 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 the fault energy let-through during overload and short-circuit conditions
• Two independent tripping mechanisms in one device - delayed thermal tripping for overload protection and electromechanical tripping for instant short-circuit response
• Certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL1077, covering residential, commercial, and industrial applications
• Optional bottom-fitting auxiliary contact mounts on the S200 to save 50% space

Applications:

• Overload and short-circuit protection in residential electrical installations
• Circuit protection in commercial buildings and offices
• Industrial electrical installations and control panels
• Projects requiring IEC/EN 60898-1 or IEC/EN 60947-2 compliance
