2CDS213001R0044 ABB SH203-C4 MCB 3P 4A C Curve 6kA DIN Rail

The ABB SH203-C4 (article 2CDS213001R0044) is a 3-pole miniature circuit breaker from the SH200 Compact Home series, rated at 4 A with a C tripping characteristic. It combines two independent tripping mechanisms - a thermal element that responds to sustained overloads and an electromechanical element that disconnects the circuit instantly under short circuit conditions. AC breaking capacity is 6 kA at 230/400 V, making it a practical choice for residential distribution boards.

Technical specifications:

• Series: SH203-C4
• ABB article number: 2CDS213001R0044
• EAN: 4016779631259
• Type: Miniature circuit breaker (MCB)
• Poles: 3P
• Rated current: 4 A
• Tripping characteristic: C
• Breaking capacity: 6 kA (AC)
• System voltage: 230/400 V AC
• Standard: IEC/EN 60898-1

Features and benefits:

• Current limiting design reduces energy let-through to downstream equipment during fault conditions
• Thermal tripping element protects wiring and connected loads from damage caused by sustained overcurrents
• Electromechanical short circuit trip provides fast disconnection when fault currents are detected
• 6 kA breaking capacity at 230/400 V AC handles fault levels found in typical residential and light commercial installations
• Certified to IEC/EN 60898-1, confirming suitability for residential circuit protection applications

Applications:

• Final circuit protection in residential consumer units and distribution boards
• Lighting and socket outlet branch circuits in homes and apartments
• 3-pole circuit protection where a C characteristic suits loads with moderate inrush currents
• Small commercial or office premises requiring compact DIN rail-mounted overcurrent protection
