Schneider Electric Square D HDL36030 Circuit Breaker

Schneider Electric's Square D HDL36030 PowerPact H molded-case circuit breaker is a 30A, 3-pole unit-mount MCCB designed for 600 VAC service, delivering thermal-magnetic overcurrent protection for feeders and motor circuits. As a member of the PowerPact H family, HDL36030 supports line and load lugs and provides interrupting ratings up to 14 kA at 600 VAC (with higher ratings at lower voltages: 25 kA at 240 VAC and 18 kA at 480 VAC), making it suitable for multi‑circuit distribution across industrial panels. The device is rated for both AC and DC applications, with a 600 VAC / 250 VDC rating, and is 80% rated for continuous loads. Its thermal-magnetic trip mechanism ensures coordinated protection against overloads and short circuits, helping protect downstream equipment and wiring. Ideal uses include power distribution panels, motor control centers, and machine-control interfaces where a compact, high‑interrupting‑capacity MCCB is required, and three‑phase circuits require simultaneous disconnection. The HDL36030’s PowerPact H‑Frame geometry and unit-mount design streamline replacement in compatible Square D enclosures, providing dependable protection in demanding industrial environments.
