Eaton / Cutler-Hammer PDG23M0150TFFL Molded Case Circuit Breaker

This Power Defense Frame 2 breaker is designed for direct integration into Eaton Power Defense panelboards, switchboards, and standalone enclosures. It is not intended for use in load centers that require plug-on breakers.

Yes. As a 3-pole complete molded case circuit breaker, it is designed specifically for 3-phase applications. It supports overcurrent and short-circuit protection across 240V, 480V, and 600V AC networks.

Yes, this molded case circuit breaker is rated for continuous DC use up to 250VDC. At this voltage, it provides a 22 kAIC short-circuit interrupting rating.

The terminals on this breaker accept conductors ranging from 4 AWG to 4/0 AWG. The lugs are dual-rated for both aluminum and copper (Al/Cu) wire, allowing flexibility based on your facility's wiring standards.

No, this specific model features fixed thermal and fixed magnetic trip settings. If your application requires field-adjustable long-time or instantaneous pickup curves, you will need a breaker with a Power Xpert electronic trip unit or an adjustable thermal-magnetic unit.

In Eaton's Power Defense nomenclature, the letter M specifies the interrupting rating tier. It confirms the breaker is rated for 65 kAIC at 480VAC and 100 kAIC at 240VAC, which determines its suitability for commercial and industrial systems with high available fault current.

The LI (Long-Time and Instantaneous) thermal-magnetic trip unit provides two layers of safety. The thermal element safely trips the breaker during sustained overloads, while the magnetic element reacts immediately to clear high-level short circuits, minimizing equipment damage.

The PDG23M0150TFFL utilizes a bolt-on connection. Rather than plugging onto the bus, it must be physically bolted to the chassis or bus bars of compatible panelboards and switchboards, ensuring a rigid, low-resistance mechanical connection.
