H-Frame MCCB, 40 A, 3-Pole, 600 V AC, I-Line

Product Description

This molded case circuit breaker is a PowerPacT H-frame unit engineered for distribution applications requiring reliable thermal-magnetic protection. Rated 40 A at 600 V AC with 3 poles, it provides coordinated short-circuit interrupting performance including 25 kA at 600 VAC, with higher ratings at lower system voltages. The device features I-Line terminations on the line side for rapid panelboard/bus connection and mechanical lugs on the load side, supporting 14 to 3/0 AWG copper or aluminum conductors. It carries an 80% continuous current rating with ABC phase connection and is suitable for 50/60 Hz systems. The breaker conforms to UL, CSA, NOM, and IEC 60947-2 standards and includes an integral push-to-trip for verification and maintenance. Its H-frame construction with dual-break rotating contacts helps limit peak let-through current under fault conditions, improving system protection. Typical implementations include commercial and industrial distribution panels where compact form factor, I-Line compatibility, and consistent interrupting ratings across common voltages are required.
