ABB S201P-K6 6A 1-Pole 277 V Circuit Breaker

Meet the ABB S201P-K6 6A 1-Pole 277 V Circuit Breaker—a compact, dependable protection device designed for commercial and light industrial electrical systems. With a 6 A current rating and a single-pole design, it shields a dedicated 277 V branch circuit from overloads and fault conditions while fitting neatly into standard panel spaces.

Key specifications at a glance

• Part number: S201P-K6
• Current rating: 6 A
• Pole configuration: 1-Pole
• Voltage rating: 277 V
• Application: Protection for individual 277 V circuits in commercial or light industrial environments

Designed for reliability in real-world installations, the ABB S201P-K6 combines a straightforward, single-pole form with a robust thermal-magnetic trip mechanism. This means predictable performance: it trips quickly under short circuits and gradually under sustained overloads, helping safeguard wires, outlets, lighting, and control circuits without unnecessary interruptions.

Why this 6A, 1-Pole breaker is a smart choice

• Precise protection for small loads: A 6 A rating is ideal for low-current lighting runs, signaling circuits, or small control circuits that need dependable overcurrent protection without nuisance trips.
• 277 V readiness: Specifically suited for commercial lighting and equipment fed from 277 V distribution, helping you maintain code-compliant, safe installations in office buildings, retail spaces, and other commercial facilities.
• Single-pole simplicity: With a 1-pole design, it protects a single branch circuit while minimizing space use in the panel. Ideal for upgrading or adding protection to an individual line.
• Reliable ABB engineering: Built on ABB’s proven electrical protection platform, offering consistent performance, long service life, and compatibility with ABB panel systems that support the S201P family.
• Easy integration: Works with standard electrical enclosures and panel boards designed for S201P-series breakers, helping reduce installation time and complexity.

Practical use cases

• 277 V lighting circuits in commercial interiors (offices, lobbies, conference rooms) where a dedicated 6 A protection device helps prevent overloads without frequent trips.
• Small control circuits for HVAC fans, pumps, or building automation equipment powered from 277 V supplies.
• Dedicated power feeds for signage or specialty loads that require careful current limiting to stay within a tight electrical design margin.

How it solves common problems

In environments where loads are near the edge of a breaker’s rating, a precise 6 A breaker like the S201P-K6 helps prevent nuisance trips while still delivering fast, reliable fault protection. The 1-pole configuration keeps wiring simple and reduces panel crowding, making it easier to manage and troubleshoot circuits. For facilities aiming to meet electrical code requirements for branch-circuit protection, this ABB breaker provides a dependable, well-matched option for 277 V distributions.

Tips for getting the most out of your ABB S201P-K6

• Verify that the target circuit operates at 277 V and that the load current is appropriate for a 6 A protection device to minimize nuisance trips.
• Ensure your panel or enclosure supports S201P-series breakers and that the mounting configuration aligns with a 1-pole installation.
• Use this breaker for dedicated branch circuits where precise protection is required for small loads within a 277 V system.
• Maintain clear labeling on the panel to indicate the protected circuit and its 6 A rating to help technicians diagnose issues quickly.

Choosing the ABB S201P-K6 6A 1-Pole 277 V Circuit Breaker means opting for dependable, purpose-built protection for your 277 V circuits. Its focused current rating, compact design, and robust ABB engineering make it a practical, long-lasting choice for professionals who demand clarity, reliability, and efficiency in electrical protection.
