2CDS253001R0634 ABB SH203-C63 MCB 3P 63A C Curve 6kA DIN Rail

The ABB S203-C63 (article 2CDS253001R0634) is a 3-pole 63 A miniature circuit breaker from the S200 series, built to protect three-phase circuits against both overload and short circuit faults. It carries a C tripping characteristic and a 6 kA AC breaking capacity, making it a compact and capable choice for general distribution in residential, commercial, and industrial installations.

Technical specifications:

• Series: S203-C63 (S200 family)
• ABB article number: 2CDS253001R0634
• EAN: 4016779551076
• Poles: 3P
• Rated current: 63 A
• Tripping characteristic: C
• Breaking capacity: 6 kA (AC)
• Standards: IEC/EN 60898-1, IEC/EN 60947-2, UL1077

Features and benefits:

• Current limiting design restricts the energy passed to downstream components during a fault event
• Separate thermal and electromagnetic trip mechanisms handle overload and short circuit conditions independently
• Bottom-fitting auxiliary contact mounts directly onto the breaker body, reducing the space required by accessories by up to 50%
• C tripping characteristic handles loads that produce moderate inrush currents at start-up without nuisance tripping
• Complies with IEC/EN 60898-1, IEC/EN 60947-2, and UL1077, covering a wide range of residential, commercial, and industrial application requirements

Applications:

• Three-phase distribution boards in residential buildings and apartment complexes
• Commercial switchboards and panelboards requiring branch circuit protection
• Industrial control panels and machinery protection circuits
• General three-phase branch circuit protection where a C characteristic is specified
