ABB S530941 - Thermal-magnetic circuit breaker S203 D25 25A 3P 6kA D curve

The ABB S530941 S203 D25 series circuit breaker offers robust protection against overloads and short circuits in your electrical installation, perfect for residential, commercial and industrial applications with loads that have high inrush currents. With its D curve and 25A current rating on 3 poles, this device guarantees high performance and comprehensive protection in contexts that require a balance between safety and load capacity.

Main features:

• Type: Circuit breaker
• Brand: ABB
• Series: S203
• Model: D25
• Poles: 3P (three-pole)
• Current Rating: 25 Amps (A) per pole
• Interrupting power: 6 Kiloampere (kA)
• Interrupting curve: D (suitable for loads with high inrush currents, such as electric motors and transformers)
• Order code: S530941

• 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 D: offers a longer trip delay than curves B and C, allowing high inrush currents to pass through when starting electric motors or other inductive loads, without causing the breaker to accidentally trip.
• Compact design and easy to install on DIN rail.
• 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.

• Electrical engines
• Transformers
• Capacitor banks
• Air conditioning systems
• Lifts
• Industrial furnaces
• Other applications with inductive loads or high inrush currents
