Challenger A115R U Limit Switch

Challenger A115R U is a 15A, 120V, single-pole molded-case circuit breaker engineered for plug-in installation with a right-hook mounting in Challenger load centers. As part of Challenger’s A-series Type A family, the A115R U carries a 10,000-ampere interrupting capacity (10 kAIC) at 120V, delivering reliable overload and short-circuit protection for branch circuits in residential and light commercial applications. The device is 0.5 inches wide (about 12.7 mm), compact for use in space-constrained panels, and it uses a right-hook contact design to ensure secure seating in compatible enclosures. Designed for plug-in mounting, it allows quick replacement in Challenger load centers without removing the entire panel and is commonly cataloged as a Challenger A115R U replacement part by distributors. Applications include protecting branch circuits for lighting, outlets, and small appliances where a reliable 15A 120V protection device is needed; the A115R U variant is a standard 1-pole option in many electrical installations.
