Square D BDL36090 Three Phase Circuit Breaker

BDL36090 Square D PowerPact B-frame molded‑case circuit breaker, 3‑pole, 90 A, is designed for three‑phase protection in commercial and light industrial distribution. It is rated at 600Y/347 VAC and offers a 14 kA interrupting capacity, making it suitable for protecting feeders and motor circuits in panels and switchgear. The unit uses a thermal‑magnetic trip mechanism to provide reliable long‑time and instantaneous overcurrent protection and features line‑ and load‑side lug terminals for straightforward wiring. As part of the PowerPact B family, the BDL36090 provides a compact, rugged MCCB solution for distribution applications up to 90 A, and it integrates with other Square D/Schneider Electric equipment in a typical electrical distribution topology. Typical applications include protection of three‑phase feeders to motors, transformers, and branch circuits in commercial buildings and light industrial facilities.
