ABB S530903 - Thermal-magnetic circuit breaker S203 D10 10A 3P 6kA curve D

ABB S530903 - Thermal-magnetic circuit breaker S203 D10 10A 3P 6kA D-curve

The ABB S530903 thermal-magnetic circuit breaker S203 D10 series offers basic protection against overloads and short circuits in your electrical installation, perfect for residential and commercial applications with low electrical loads that have moderate inrush currents. With its D curve and 10A current rating on 3 poles, this device guarantees adequate performance and essential protection in contexts requiring maximum safety for low loads.

Main features:

• Type: Circuit breaker
• Brand: ABB
• Series: S203
• Model: D10
• Poles: 3P (three-pole)
• Current Rating: 10 Amps (A) per pole
• Interrupting power: 6 Kiloampere (kA)
• Interrupting curve: D (suitable for loads with moderate inrush currents, such as fluorescent lamps, small electric motors and transformers)
• Order code: S530903

• 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 during the start-up of certain 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.

• Low-wattage light points
• Low-wattage small appliances
• Alarm systems
• Command and control circuits
• Other low current loads with moderate inrush currents
• Residential and commercial installations
