ABB S202UP-K8 8A 2-Pole 277 V Circuit Breaker

The ABB S202UP-K8 8A 2-Pole 277 V Circuit Breaker is a purpose-built protection device designed for reliable overload and short-circuit protection on 277-volt branch circuits. With an 8-amp rating and a two-pole design, it safeguards two hot conductors in one compact unit, helping your commercial or industrial electrical system stay safe and available.

Why this ABB breaker stands out

• Precise 8-amp protection tailored for lighting runs, small equipment circuits, and other moderate-load applications common in commercial spaces.
• Two-pole protection ensures both conductors trip together, reducing arc risk and preventing backfeed when a fault occurs.
• 277 V readiness specifically suited for workplace electrical infrastructures that operate at 277 volts, such as commercial lighting and control circuits.
• Solid ABB reliability backed by decades of engineering, delivering consistent performance and predictable tripping behavior when it matters most.
• Simple integration designed for straightforward replacement in compatible panels, helping you minimize downtime during maintenance or updates.

Ideal applications

• Commercial lighting circuits that run on 277 V, including office buildings, retail spaces, and hospitality environments.
• Small equipment branches and control circuits where compact two-pole protection improves safety and reliability.
• Upgrade or replacement projects where a dependable 8A, 2-pole device is required to maintain panel integrity and code compliance.

What problems this solves

• Prevents damage from overloads and short circuits by interrupting power quickly and simultaneously on both lines.
• Maintains safer electrical operation in environments with 277 V distribution, reducing risk to personnel and equipment.
• Helps keep critical systems up and running by providing dependable, predictable protection in your panel lineup.

Practical guidance for use

Verify that your circuit requires 277 V operation and an 8-amp protection level. Ensure the breaker is compatible with your panel’s design and labeling, and follow standard electrical practices or consult a licensed electrician for installation and commissioning. This device is intended as a protective component within a larger electrical system, not a standalone power solution.
