• 6 A nominal rating: Provides precise protection for circuits that require tighter current control without unnecessary interruptions.
• Industrial-grade reliability: ABB’s design focuses on consistent performance across maintenance cycles and replacements.
• In-kind replacement potential: Drop‑in compatibility with existing ABB S203P‑based panels when the part number matches your application.
• Clear part-number verification: Use S203P-K1.6 to confirm compatibility with your panel and load requirements.

Ideal use cases

• Protection for motors, conveyors, pumps, and other 3‑phase loads in manufacturing lines operating at 480V.
• Panel upgrades, retrofits, or service replacements where a reliable, in‑kind ABB component is required.
• Routine maintenance planning for automation and process control systems that depend on predictable overcurrent protection.

How it protects your equipment

By reliably interrupting fault currents, the S203P-K1.6 minimizes heat buildup, reduces wear on conductors and contactors, and helps prevent damage to drives and motors. The result is improved equipment longevity and reduced unplanned downtime in busy industrial environments.

Installation and considerations

Ensure your distribution panel and wiring are suitable for 480V operation and that mounting, wiring, and termination adhere to ABB installation guidelines. Use the correct conduit, lugs, and conductor sizes for your 6 A application, and follow all safety protocols during installation and servicing.
