2CDS251001R0044 ABB SH203-C4 MCB 1P 4A C Curve 6kA DIN Rail

The ABB S201-C4 (article 2CDS251001R0044) is a single-pole miniature circuit breaker from the System pro M compact S200 range, rated at 4 A with a C tripping characteristic and a 6 kA AC breaking capacity. It protects circuits through two separate mechanisms: a delayed thermal element that trips on sustained overloads, and an electromechanical element that trips instantly on short-circuit faults.

Technical specifications:

• Series: S201-C4
• ABB article number: 2CDS251001R0044
• EAN: 4016779523349
• Configuration: 1P (single pole)
• Rated current: 4 A
• Tripping characteristic: C
• Breaking capacity: 6 kA (AC)
• Standards: IEC/EN 60898-1, IEC/EN 60947-2, UL1077

Features and benefits:

• Current-limiting design reduces the energy let-through to downstream wiring and components during fault events
• Dual tripping mechanism addresses both overload conditions (thermal) and short-circuit faults (electromechanical) within a single compact device
• C-curve characteristic is suited to general distribution circuits and loads with moderate inrush currents
• Accepts a bottom-fitting auxiliary contact accessory that saves 50% of the mounting space a side-fitting arrangement would require
• Certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL1077, qualifying it for residential, commercial, and industrial installations

Applications:

• Branch circuit protection in residential consumer units and distribution boards
• Sub-distribution panels in commercial and office buildings
• Control panel and machine wiring in industrial environments
• General overcurrent protection in IEC and UL-compliant electrical installations
