Meet the Allen-Bradley 1492-CB1H150, a compact, single-pole circuit breaker designed to protect a single branch circuit in 277 V electrical systems. With a 15 A rating, it provides precise overcurrent protection for commercial lighting, control panels, and other moderate-load circuits.

Smart protection for commercial and light-industrial spaces

Engineered for reliability in busy installations, this 1-pole breaker fits standard Allen-Bradley panels and is compatible with the 1492 family ecosystem, ensuring straightforward replacement and minimal downtime when you need a spare or a quick upgrade.

• Single-pole, 15 A rating: Protects one branch circuit from overloads and short circuits.
• 277 V operation: Suited for commercial lighting and other 277 V circuits commonly found in offices, retail, and light-industrial settings.
• Part number 1492-CB1H150: A genuine Allen-Bradley component built to match the performance and dimensions of existing installations.
• Easy integration: Install in compatible panels and replace aging or out-of-spec breakers with a trusted OEM part.

Why this model stands out? It’s purpose-built to align with Allen-Bradley’s design standards, delivering consistent trip behavior and predictable protection for your critical loads. It’s ideal as a spare part for technicians or for designers who specify reliable, readily available components for commercial electrical systems.

Practical use cases and guidance:

• Use for 277 V lighting circuits in commercial spaces (office buildings, shopping centers, schools) where a single 15 A breaker is needed to protect one leg or one circuit path.
• Integrate into control panels housing simple motor starters or automation devices that operate at 277 V and require single-pole protection.
• Keep as a high-quality replacement in maintenance inventories to minimize downtime when a breaker in the 1492 family needs replacement.

Notes for installation and safety: Ensure the new breaker matches the panel’s rating and the circuit requirements. Install by a qualified electrician following all local electrical codes and manufacturer guidelines to maintain system integrity and safety.
