2CDS213001R0635 ABB SH203-B63 MCB 3P 63A B Curve 6kA DIN Rail

The ABB SH203-B63 (article 2CDS213001R0635) is a 3-pole miniature circuit breaker from the SH200 series, rated at 63 A with a B tripping characteristic. It protects three-phase AC circuits against overcurrent and short-circuit faults, with an AC breaking capacity of 6 kA.

Technical specifications:

• Series: SH200 / SH203-B63
• ABB article number: 2CDS213001R0635
• EAN: 4016779701297
• Poles: 3P (3-pole)
• Rated current: 63 A
• Tripping characteristic: B
• AC breaking capacity: 6 kA

Features and benefits:

• 3-pole design interrupts all three phases in a single switching operation, ensuring complete circuit isolation without requiring separate single-pole devices.
• B tripping characteristic is suited to circuits supplying resistive loads and equipment with low start-up inrush currents, reducing nuisance tripping.
• 6 kA AC breaking capacity enables reliable interruption of short-circuit currents in standard low-voltage distribution systems.
• 63 A rated current makes this MCB appropriate for high-current branch circuits in industrial and commercial sub-distribution boards.

Applications:

• Overcurrent and short-circuit protection for 3-phase branch circuits in commercial and industrial distribution boards.
• Protection of resistive loads such as heating systems and lighting installations on three-phase supplies.
• Sub-distribution panels in buildings requiring 3-phase protection at 63 A.
• Low-voltage switchgear assemblies using compact 3-pole MCB modules.
