Eaton PDG21M0090TFFL: Compact, Reliable 1-Pole Protection for Your Panel

The Eaton PDG21M0090TFFL is a 90 A, 600 V, 1-pole molded case circuit breaker designed to provide dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. With a thermal-magnetic trip unit, it delivers stable, repeatable protection across a wide range of operating conditions, helping to prevent nuisance trips and equipment damage.

Why this breaker stands out

• Efficient panel space utilization: its compact molded case design fits neatly into tighter panel layouts, maximizing usable space in residential, commercial, and light industrial installations.
• Thermal-magnetic protection: combines a thermal element for overload protection with a magnetic element for rapid short-circuit interruption, delivering precise protection when it matters most.
• OEM-compatible installation: specifically engineered to be compatible with matching Eaton OEM load centers and panelboards, simplifying upgrades, replacements, and service compatibility.
• Versatile applications: ideal for a range of settings—homes, office buildings, and light industrial environments—where reliable branch circuit protection is essential.

How it protects your system

In normal operation, the thermal element monitors temperature rise from continuous loads, preventing overheating. If a fault current spikes during a short circuit, the magnetic trip engages quickly to interrupt the circuit, minimizing damage to wiring, devices, and downstream equipment. This combination provides durable protection in environments with varying temperatures and load profiles.
