2CDS253001R0204 ABB SH203-C20 MCB 3P 20A C Curve 6kA DIN Rail

The ABB S203-C20 (article 2CDS253001R0204) is a 3-pole, 20 A miniature circuit breaker from the S200 series, equipped with a C-curve trip characteristic and rated for a 6 kA breaking capacity in AC systems. It incorporates two separate tripping mechanisms: delayed thermal tripping to handle overload conditions, and electromechanical tripping for immediate disconnection on short circuit faults. Certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL1077, it is suitable for residential, commercial, and industrial applications.

Technical specifications:

• Series: S203-C20 (S200 family)
• ABB article number: 2CDS253001R0204
• EAN: 4016779468107
• Rated current: 20 A
• Poles: 3P
• Trip characteristic: C
• Breaking capacity: 6 kA (AC)

Features and benefits:

• Current limiting design reduces let-through energy during fault events
• Delayed thermal tripping provides time-dependent protection against sustained overloads
• Electromechanical tripping delivers fast disconnection under short circuit conditions
• Bottom-fitting auxiliary contact can be added to save up to 50% panel space
• Complies with IEC/EN 60898-1, IEC/EN 60947-2, and UL1077 for broad installation approval

Applications:

• Protection of 3-phase branch circuits in residential consumer units and distribution boards
• Sub-distribution and metering panels in commercial buildings
• Industrial control panels and machinery power circuits
• Three-phase applications requiring C-curve characteristics at 20 A
