Eaton PDG23M0150TFFL 150A 3-Pole 600V Molded Case Circuit Breaker | Power Defense Feed-Thru | 65kAIC

Eaton PDG23M0150TFFL — Power Defense Molded Case Circuit Breaker, 150A, 3-Pole, 600V, Feed-Thru

The Eaton PDG23M0150TFFL is a 150-amp, 3-pole molded case circuit breaker (MCCB) from Eaton's globally rated Power Defense series. Designed for demanding industrial and commercial electrical systems, this Frame 2 breaker delivers robust overcurrent protection with a 65 kAIC interrupting rating at 480VAC — one of the highest in its class for this amperage range.

The feed-thru (TFFL) terminal configuration supports both line-side and load-side connections, making it ideal for panelboard feed-through applications and direct replacement of legacy Eaton Series C HFD3150 circuit breakers. It is globally rated and certified to UL 489, IEC, CSA, and CCC standards, and is fully RoHS compliant.

• Feed-Thru Ready: The TFFL terminal configuration supports both line and load connections without additional adapters, streamlining panelboard wiring.
• Direct Legacy Replacement: Drops in as a 1:1 replacement for the Eaton Series C HFD3150, simplifying retrofits and maintenance.
• Globally Rated: Meets UL 489 and IEC 60947-2 simultaneously — one breaker, worldwide compliance.
• Thermal-Magnetic Protection: Fixed trip unit provides reliable, maintenance-free protection against overloads and short circuits.
• RoHS Compliant: Meets environmental standards for use in regulated applications.

Typical Applications

• Commercial and industrial power distribution panels
• Three-phase electrical systems up to 600VAC
• Motor branch circuit and feeder protection
• Data centers and critical infrastructure
• Manufacturing equipment and HVAC systems
• Retrofit and replacement of legacy HFD3150 breakers

What Is a Molded Case Circuit Breaker (MCCB)?

A molded case circuit breaker (MCCB) is a type of electrical protection device housed in a molded insulating case. It automatically interrupts current flow when a fault — such as an overload or short circuit — is detected. Unlike fuses, MCCBs can be reset after tripping, making them ideal for high-traffic commercial and industrial applications where uptime is critical.

What Does "Feed-Thru" (TFFL) Mean?

The feed-thru (TFFL) designation means the breaker includes both line-side and load-side terminal lugs at the factory. This allows the breaker to be wired in series within a panelboard — power enters the line terminals and passes through (or is protected at) the load terminals — without requiring separate terminal block accessories.
