Schneider Electric BJA36070 I-Line Circuit Breaker

Schneider Electric's PowerPact B-Frame I-Line molded‑case circuit breaker, model BJA36070, is a 3‑pole, 70‑amp device rated for 600Y/347 VAC three‑phase distribution. It uses I‑Line mounting for plug‑in installation in Schneider Electric panelboards, features a thermal‑magnetic trip, and carries an 80% rating at 40°C ambient with a 25 kAIC interrupting capacity at the rated voltage. The BJA36070 is part of the PowerPact B‑Frame family, designed for high‑performance protection in commercial and light industrial power distributions, offering reliable short‑circuit protection for feeders and branch circuits. This model is noted for its non‑interchangeable trip and its compatibility with PowerPact B‑Frame accessories, making it a straightforward replacement in existing I‑Line installations where 347 VAC three‑phase protection is required. Typical applications include motor feeders, HVAC equipment, pumps, and other controlled loads in distribution panels and switchgear that operate on 347 VAC three‑phase systems.
