Challenger A115LN-U Single-Pole Circuit Breaker

Challenger A115LN-U is a Type A, single‑pole miniature circuit breaker rated at 15 amps and 120 volts, engineered for plug‑in installation in Challenger load centers. As a 1‑pole device, it provides overcurrent protection for a 120V circuit and features the familiar Challenger form factor that snaps into compatible panels for fast, tool‑free replacement. The A115LN‑U is specified for use in Challenger Type A panels and is commonly used in residential and light commercial wiring where a 15A branch circuit breaker is required, aligning with standard 120V branch circuits such as lighting and receptacle runs in appropriately sized electrical systems. In practice, this model is selected when a Challenger‑pattern 1‑pole, 15A breaker is specified and a plug‑in mounting is preferred for straightforward retrofits or panel upgrades. While similar in appearance to other Challenger A‑series breakers, the A115LN‑U remains dedicated to Challenger/Type A panel compatibility and is sold through distributors that list it as a 15A, 120V, 1‑pole unit designed to plug into Challenger load centers.
