Square D's PowerPact B-Frame molded‑case circuit breaker, model BJA160155, is a 1‑pole device rated for 15 A with a 600Y/347 VAC (250 VDC) rating. It uses a thermal‑magnetic trip for overload and short‑circuit protection and lists an interrupt rating of 25 kA (50 kA in certain configurations). Designed for I‑Line mounting, it plugs into compatible Square D panels to protect a single branch circuit. Typical applications include protecting small branch circuits in commercial electrical distributions where compact MCCB protection is required for lighting, receptacles, and other low‑amp loads.
