2CDS251001R0405 ABB SH203-B40 MCB 1P 40A B Curve 6kA DIN Rail

The ABB S201-B40 (article 2CDS251001R0405) is a 1-pole, 40 A miniature circuit breaker from the System pro M compact S200 series, built to protect electrical circuits against overload and short-circuit faults. It carries a B tripping characteristic and a 6 kA AC breaking capacity, making it suitable for residential, commercial, and industrial distribution applications.

Technical specifications:

• Series: S201-B40
• ABB article number: 2CDS251001R0405
• EAN: 4016779465403
• Rated current: 40 A
• Configuration: 1P (1 pole)
• Tripping characteristic: B
• Breaking capacity: 6 kA (AC) at 230/400 V AC
• Standards: IEC/EN 60898-1, IEC/EN 60947-2, UL1077

Features and benefits:

• Current-limiting design restricts the energy let through to the circuit during a fault event
• Two independent tripping mechanisms: delayed thermal response for overload conditions and electromechanical response for short-circuit events
• 6 kA AC breaking capacity at 230/400 V AC covers fault levels encountered across residential, commercial, and industrial installations
• Supports a bottom-fitting auxiliary contact that saves 50% of space on the device
• Certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL1077, permitting use across a wide range of residential, commercial, and industrial applications

Applications:

• Branch circuit protection in residential consumer units and distribution boards
• Overcurrent protection in commercial switchgear and building services panels
• Industrial control panel circuit protection requiring IEC- and UL-listed devices
• General wiring protection against overload and short-circuit conditions
