ABB S468404 - Circuit breaker S203 C40 40A 3P 6kA curve C

Safety and reliability for high loads


The ABB S468404 Series S203 C40 circuit breaker offers robust protection against overloads and short circuits in your electrical system, perfect for residential, commercial and industrial applications with high loads. With its C curve and 40A current rating on 3 poles, this device guarantees high performance and reliability in contexts where maximum protection is required.

Main features:

• Type: Circuit breaker
• Brand: ABB
• Series: S203
• Model: C40
• Poles: 3P (three-pole)
• Current rating: 40 Amperes (A) per pole
• Interrupting power: 6 Kiloampere (kA)
• Switching curve: C (suitable for loads with moderate inrush currents)
• Order code: S468404

• Protects electrical circuits from overloading, interrupting current flow before cables overheat and cause fires.
• Protects against short circuits, quickly disconnecting the power supply in the event of sudden faults that cause an abrupt current surge.
• Curve C: offers a balanced response to overloads and transient current peaks (inrush currents), making it suitable for a wide range of high load applications.
• Compact design and easy DIN-rail installation.
• Certifications: CEI-EN 60898-1, CEI-EN 60947-2, UL1077 and CSA 22.2 No. 235 (except 4.5kA version).
• Compatible with DDA 200 series differential blocks for additional protection against leakage currents.

• Industrial ovens
• Large air conditioners
• Heat pumps
• Industrial machinery
• High-intensity lighting systems
• Other high-current loads
