2CDS253001R0404 ABB SH203-C40 MCB 3P 40A C Curve 6kA DIN Rail

The ABB S203-C40 (article 2CDS253001R0404) is a 3-pole miniature circuit breaker from the S200 System pro M compact series, rated at 40 A with a C tripping characteristic. As a current-limiting device with a 6 kA AC breaking capacity, it provides both overload and short circuit protection for residential, commercial, and industrial electrical installations.

Technical specifications:

• Series: S200 (S203-C40)
• ABB article number: 2CDS253001R0404
• EAN: 4016779468404
• Poles: 3P
• Rated current: 40 A
• Tripping characteristic: C
• Breaking capacity: 6 kA at 230/400 V AC

Features and benefits:

• Current-limiting design reduces let-through energy during fault events
• Delayed thermal tripping mechanism protects against sustained overload conditions
• Electromechanic tripping mechanism delivers fast response to short circuit currents
• Bottom-fitting auxiliary contact can be added while saving 50% of the space compared to side-mounted accessories
• Complies with IEC/EN 60898-1, IEC/EN 60947-2, and UL1077 for use across a wide range of international applications

Applications:

• Overcurrent and short circuit protection in residential distribution boards
• Circuit protection in commercial electrical installations
• Branch circuit protection in industrial control panels
• Three-phase load circuits requiring 40 A rated protection with C characteristic response
