ABB S530927 - Thermal-magnetic circuit breaker S203 D16 16A 3P 6kA curve D

ABB S530927 - S203 D16 16A 3P 6kA D-curve circuit breaker

The ABB S530927 S203 D16 series circuit breaker offers comprehensive protection against overloads and short circuits in your electrical installation, perfect for residential, commercial and industrial applications with loads that have moderate inrush currents. With its D curve and 16A current rating on 3 poles, this device provides a balance between performance and safety in contexts requiring versatile protection.

Main features:

• Type: Circuit breaker
• Brand: ABB
• Series: S203
• Model: D16
• Poles: 3P (three-pole)
• Current Rating: 16 Amps (A) per pole
• Interrupting power: 6 Kiloampere (kA)
• Interrupting curve: D (suitable for loads with moderate inrush currents, such as small power electric motors, transformers and fluorescent lamps)
• Order code: S530927

• 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.

• Small power electric motors
• Transformers
• Fluorescent lamps
• General loads with moderate inrush currents
• Residential and commercial installations
• Light industrial machinery
