2CDS211001R0255 ABB SH203-B25 MCB 1P 25A B Curve 6kA DIN Rail

The ABB SH201-B25 (article 2CDS211001R0255) is a single-pole miniature circuit breaker from the ABB SH200 Compact Home series, rated at 25 A with a B tripping characteristic and a 6 kA breaking capacity at 230/400 V AC. It is built for residential electrical installations and uses two independent tripping mechanisms to guard against both overload and short circuit faults. The delayed thermal mechanism responds to sustained overload currents, while the electromechanical mechanism trips instantly under short circuit conditions.

Technical specifications:

• Series: SH201-B25
• ABB article number: 2CDS211001R0255
• EAN: 4016779630696
• Poles: 1P (single pole)
• Rated current: 25 A
• Tripping characteristic: B
• Breaking capacity: 6 kA (AC)
• Rated voltage: 230/400 V AC
• Standard: IEC/EN 60898-1

Features and benefits:

• Current limiting design reduces the energy let through to downstream equipment during a fault
• Dual tripping mechanism addresses both overload conditions (thermal) and short circuit events (electromechanical) within a single device
• B tripping characteristic suited to residential branch circuit applications
• 6 kA breaking capacity at 230/400 V AC covers the fault levels typical of residential distribution networks
• Compliance with IEC/EN 60898-1 confirms suitability for residential electrical installations

Applications:

• Branch circuit protection in residential consumer units and distribution boards
• Protection of lighting circuits in homes and apartments
• Socket outlet circuit protection in domestic installations
• Final circuit protection in residential electrical panels
