2CDS253001R0105 ABB SH203-B10 MCB 3P 10A B Curve 6kA DIN Rail

The ABB S203-B10 (article 2CDS253001R0105) is a 3-pole miniature circuit breaker from the System pro M compact S200 series, rated at 10 A with a B tripping characteristic and an AC breaking capacity of 6 kA. It guards circuits against both overload and short-circuit faults through two separate tripping mechanisms integrated into a single compact device.

Technical specifications:

• Series: S203-B10
• ABB article number: 2CDS253001R0105
• EAN: 4016779468701
• Poles: 3P
• Rated current: 10 A
• Tripping characteristic: B
• Breaking capacity: 6 kA (AC)
• Operating voltage: 230/400 V AC

Features and benefits:

• Current limiting design reduces let-through energy during fault conditions.
• Delayed thermal tripping element handles overload protection; a separate electromechanical element responds to short-circuit events.
• Meets IEC/EN 60898-1, IEC/EN 60947-2, and UL1077 standards, covering residential, commercial, and industrial installation requirements.
• Optional bottom-fitting auxiliary contact mounts directly onto the device body and saves up to 50% space within the panel enclosure.
• Part of the wider S200 family offering characteristics B, C, D, K, and Z across configurations from 1P to 4P, enabling flexible system design.

Applications:

• Branch circuit protection in residential distribution boards and consumer units.
• Sub-circuit and feeder protection in commercial electrical installations.
• Circuit protection in industrial control panels and machinery enclosures.
• Three-phase power distribution circuits requiring 10 A rated current with 6 kA AC short-circuit withstand.
