Square D FH26030AC Molded Case Circuit Breaker

FH26030AC is Square D's two‑pole molded‑case circuit breaker, delivering 30 A of current protection for 600 V AC (250 V DC) circuits, designed for thermal‑magnetic overcurrent protection in I‑Line panel setups. This I‑Line MCCB carries an 18 kA interrupting rating at 600 V and is 80% rated for continuous duty, making it suitable for branch feeders and short‑circuit protection in commercial and light industrial power‑distribution applications. The device accepts 14‑4 AWG aluminum or copper conductors on the load side with line‑side I‑Line connections, enabling reliable, compact mounting within Square D enclosures. With a 2‑pole configuration, the FH26030AC provides coordinated, fast‑trip protection for paired conductors and is commonly used where a compact, high‑rupturing‑capacity protection solution is required in modern electrical panels. This model is part of Square D's molded‑case line and is intended for use in compatible enclosures and with compatible trip units, offering straightforward replacement in existing installations.
