ABB S531818 - Thermal-magnetic circuit breaker S201 NO C40 40A 1P+N 6kA curve C

ABB S531818 - Circuit Breaker S201 NA C40 40A 1P+N 6kA C-curve

The ABB S201 NA C40 series circuit breaker S531818 offers comprehensive protection against overloads and short circuits in single-phase installations with neutral, perfect for residential and commercial applications requiring reliable and robust protection. With its C curve and 40A current rating on one pole plus neutral, this device guarantees high performance and maximum safety for single-phase loads with neutral.

Main features:

• Type: Circuit breaker
• Brand: ABB
• Series: S201
• Model: NA C40
• Configuration: 1P+N (one pole plus neutral)
• Current rating: 40 Amps (A)
• Interrupting power: 6 Kiloampere (kA)
• Interrupting curve: C (suitable for loads with moderate inrush currents, such as incandescent lamps, electric ovens and washing machines)
• Order code: S531818

• 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 longer trip delay than curves B and D, allowing moderate inrush currents to pass through during the start-up of certain loads, without causing the breaker to trip accidentally.
• 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.

• Residential and commercial electrical installations
• Lighting
• Electrical ovens
• Washers
• Air conditioners
• Other single-phase loads with neutral
