Square D BJA160205 I-Line Circuit Breaker

Square D's PowerPact B I-Line molded‑case circuit breaker, model BJA160205, is a 1‑pole, 20‑amp device designed for plug‑in installation in I‑Line panelboards. Rated for 600Y/347 VAC, it uses a thermal‑magnetic trip mechanism and carries interrupting ratings up to 25 kA at 600 VAC (65 kA at 480 VAC and 100 kA at 240 VAC, depending on the system voltage), enabling robust protection for feeders and branch circuits in commercial and light‑industrial distributions. As part of the PowerPact B‑Frame family, the BJA160205 uses an I‑Line connection for secure, modular mounting in compatible Square D panels. This single‑pole breaker is commonly used for lighting and general branch circuits on 347 V systems within appropriate 600Y/347 VAC distribution schemes, and it is manufactured by Square D, a Schneider Electric brand known for industrial electrical distribution products.
