Eaton PDG23M0035TFFL Power Defense 35A 3-Pole 600V Molded Case Circuit Breaker | Feed-Thru

Eaton PDG23M0035TFFL — Power Defense Molded Case Circuit Breaker, 35A, 3-Pole, 600V, Feed-Thru

The Eaton PDG23M0035TFFL is a high-performance 35-amp, 3-pole, 600V molded case circuit breaker from Eaton's globally rated Power Defense (PD2) Frame 2 platform. Engineered for demanding commercial and industrial power distribution systems, this breaker delivers superior fault protection with a 65 kAIC interrupting capacity at 480V — making it one of the highest-rated breakers in its class.

Configured with Feed-Thru (load-only) standard terminals and a fixed thermal-magnetic (T-M) trip unit, the PDG23M0035TFFL is designed for reliable overload and short-circuit protection in panelboards and switchboards. It is a direct replacement for the legacy HFD3035 and compatible Eaton Frame 2 applications, reducing downtime during upgrades.

Key Features

• 35A continuous current rating — ideal for branch circuit and feeder protection
• 3-Pole, 600V AC — suitable for 3-phase commercial and industrial systems
• 65 kAIC @ 480V (UL) — industry-leading interrupting capacity for its frame size
• Fixed Thermal-Magnetic Trip Unit — reliable, non-adjustable overload and short-circuit protection
• Feed-Thru Configuration (Load-Only Terminals) — designed for downstream connection in panelboards
• Power Defense Frame 2 platform — globally rated for UL, IEC, CSA, and CCC standards
• Direct replacement for HFD3035 — backward-compatible for easy upgrades
• Compact Form Factor — 88.9mm (D) × 152.4mm (H) × 104.6mm (W)

Technical Specifications

What Is a Feed-Thru Molded Case Circuit Breaker?

A feed-thru (or feed-through) circuit breaker is configured with load-side terminals only. Power is fed into the breaker from the bus bars of the panelboard or switchboard, and the breaker connects on the load side. This design is standard in distribution panels where the breaker is mounted directly into a pre-wired bus assembly, simplifying installation and ensuring a clean, organized wiring layout.

Why Choose the Eaton Power Defense Platform?

Eaton's Power Defense series is a globally rated molded case circuit breaker platform designed to meet UL, IEC, CSA, and CCC standards within a single product. This means fewer SKUs to manage across international projects, simplified procurement, and consistent protection performance. The Frame 2 platform is engineered for high fault-current environments, making it a trusted choice for commercial buildings, industrial facilities, data centers, and utility applications.

Compatible Applications

• Commercial and industrial panelboards
• Motor control centers (MCC)
• Switchboards and switchgear
• Distribution panels in 480V 3-phase systems
• Upgrade or replacement for legacy Eaton HFD3035 breakers

Frequently Asked Questions

What does PDG23M0035TFFL replace?
The PDG23M0035TFFL is a direct replacement for the Eaton HFD3035 and other compatible Frame 2 breakers. It fits the same panelboard footprint, making it an easy drop-in upgrade.

What is the interrupting rating of the PDG23M0035TFFL?
This breaker carries a 65 kAIC interrupting capacity at 480V (UL rated), and 18 kAIC at 600V. This high interrupt rating makes it suitable for installations with high available fault current.

Is the PDG23M0035TFFL UL listed?
Yes. The PDG23M0035TFFL is certified to UL 489, as well as CSA, IEC 60947-2, and CCC — making it globally compliant for commercial and industrial use.

What is the difference between PDG23M0035TFFL and PDG23M0035TFFJ?
The primary difference is the terminal configuration. The TFFL variant uses feed-thru (load-only) terminals, while the TFFJ variant includes standard line and load terminals for direct wiring on both sides.

What does the "M" designation mean in PDG23M0035TFFL?
In Eaton's Power Defense catalog numbering, the "M" denotes the higher interrupt rating variant — specifically 65 kAIC at 480V, compared to the "G" variant which is rated at 35 kAIC at 480V.
