2CDS211001R0205 ABB SH203-B20 MCB 1P 20A B Curve 6kA DIN Rail

The ABB SH201-B20 (article 2CDS211001R0205) is a single-pole miniature circuit breaker from the SH200 Compact Home range, rated at 20 A with a B tripping characteristic. It provides 6 kA AC breaking capacity and protects residential circuits against both sustained overloads and short-circuit faults through two independent tripping mechanisms.

Technical specifications:

• Series: SH200 (type SH201-B20)
• ABB article number: 2CDS211001R0205
• EAN: 4016779630672
• Rated current: 20 A
• Poles: 1P (single pole)
• Tripping characteristic: B
• Breaking capacity: 6 kA (AC) at 230/400 V

Features and benefits:

• Current limiting design reduces the energy let through to downstream components during a fault
• Delayed thermal tripping element handles overload conditions, while a separate electromechanical element trips instantly on short-circuit currents
• B characteristic is suited to resistive and lightly inductive loads such as lighting and general-purpose household circuits
• 6 kA breaking capacity at 230/400 V AC covers the fault levels found in typical residential distribution boards
• Meets IEC/EN 60898-1, confirming suitability for residential installation applications

Applications:

• Final circuit protection in domestic consumer units and distribution boards
• Overload and short-circuit protection for residential lighting circuits
• Branch circuit protection for general household socket-outlet rings
• Single-pole circuit protection in home electrical installations
