Schneider Electric A1B130 Molded Case Circuit Breaker

Schneider Electric's Square D A1B130 molded‑case circuit breaker is a bolt‑on, single‑pole protective device from the A1‑E frame family, designed for use in compatible Square D panelboards and enclosures. It is rated 30 A for 120 VAC service and provides thermal‑magnetic protection with an interrupting rating of 10 kA at 120 VAC, suitable for protecting a single‑phase branch circuit from overloads and short circuits. The A1B130 designation identifies a 1‑pole, 30‑amp unit within the A1/E family (A1B130/A1‑130) and confirms its bolt‑on mounting configuration, making it straightforward to replace in appropriate Square D installations. Although compact, the device is intended for dependable protection in residential to light commercial applications, safeguarding circuits that feed lighting, receptacles, and small motors when used with correct Square D enclosures and panel systems.
