Eaton FDE316035 - 160 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Engineered for dependable protection in three‑phase power systems, the Eaton FDE316035 is a 160 A, 480 V, 3‑pole bolt‑on molded case circuit breaker designed to safeguard branch circuits in panelboards and load centers. Built for durability, it combines a secure mounting method with precise, repeatable protection to keep commercial and light industrial electrical environments running smoothly.

Key advantages that matter in the real world

• Secure bolt‑on mounting delivers a rigid, vibration‑resistant bus connection that stays firmly seated, even in equipment racks or spaces with movement and vibration.
• Thermal‑magnetic trip unit provides stable overload protection (thermal) and fast response to short circuits (magnetic), ensuring predictable protection performance under varying loads and fault conditions.
• OEM panel compatibility is designed to pair with matching load centers and panelboards, promoting coordinated protection and reliable system labeling.
• Three‑pole design for 3‑phase systems ideal for residential, commercial, and light industrial applications that rely on balanced three‑phase distribution.
• Practical, field‑ready solution aimed at protecting feeders, branch circuits, motors, and other key loads without overcomplicating panel maintenance.
