ABB S203U-K13 - 13A, 240VAC, 3-Pole, Circuit Breaker

Meet the ABB S203U-K13 — a purpose-built 3-pole circuit breaker delivering dependable overcurrent protection for three-phase systems. Rated at 13A and up to 240VAC, this unit is designed to live in the heart of your distribution panels, switchboards, and control panels, providing reliable safety for industrial, commercial, and OEM applications.

• Three-pole protection for all-phase safety: Simultaneous disconnection of all three lines ensures safer maintenance and reduces the risk of phase-imbalance or backfeed in 3-phase circuits.
• Precise 13A protection at 240VAC: Calibrated to shield motors, feeders, and control circuits without nuisance trips in typical three-phase loads.
• Versatile installation footprint: Ideal for panelboards, switchboards, and motor control centers where compact, reliable protection is required in 240VAC systems.
• Industrial-grade reliability: Built by ABB to deliver consistent performance in demanding environments, supporting long service life in critical distribution points.

This 13A, 240VAC, 3-pole circuit breaker is perfectly suited for protecting small- to mid-size three-phase motors, feeders on manufacturing lines, and essential equipment in HVAC, pumps, and processing systems. It’s a practical choice when you need robust overcurrent protection in distribution panels and control centers without sacrificing space or simplicity.
