Square D FA34030N Industrial Molded Case Circuit Breaker

The Square D FA34030N is a three-pole molded‑case circuit breaker (MCCB) rated for 480 V AC and 30 A, part of Square D’s FA family from Schneider Electric. Built for industrial distribution, it employs a thermal-magnetic trip mechanism to protect three‑phase feeders and motor circuits and is designed for I‑Line panel mounting in FA‑series enclosures. The device offers an interrupting capacity up to 18 kA at 480 VAC, with phase connections ABC and long‑time plus instantaneous trip functions for selective protection and fast fault isolation. This FA34030N model is compact yet robust, intended for use in industrial control panels, machine feeders, and other high‑demand installations where reliable overcurrent protection is required. Its 30 A rating and 480 V rating align with common industrial supply standards, and the FA family is known for standardized trip characteristics and compatibility with Square D/Schneider Electric distribution gear.
