ABB S529228 - Circuit breaker S204 C20 20A 4P 6kA curve C

Reliable protection for three-phase systems with moderate loads


The ABB S529228 series S204 C20 circuit breaker offers comprehensive protection against overloads and short circuits in three-phase systems, perfect for residential, commercial and industrial applications requiring reliable and robust protection. With its C curve and 20A current rating on 4 poles, this device guarantees high performance and maximum safety for three-phase loads with moderate inrush currents.

Main features:

• Type: Circuit breaker
• Brand: ABB
• Series: S204
• Model: C20
• Poles: 4P (three-phase + neutral)
• Current rating: 20 Amps (A) per pole
• Interrupting power: 6 Kiloampere (kA)
• Interrupting curve: C (suitable for loads with moderate inrush currents, such as electric motors, transformers and industrial furnaces)
• Order code: S529228

• 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 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.

• Three-phase electric motors
• Three-phase transformers
• Industrial furnaces
• Three-phase air conditioning systems
• Heavy industrial machinery
• Other three-phase loads with moderate inrush currents
