Eaton FD3070 - 70 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Eaton FD3070 is a 70 A, 600 V, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short‑circuit protection in panelboards and loadcenters.

Built for reliability in residential, commercial, and light industrial environments, this thermal‑magnetic breaker combines rugged hardware with precise protection settings to guard your electrical system against faults. The result is safer operation and fewer interruptions in daily workflows, outages, or busy service environments.

Key features

• Secure bolt‑on mounting provides a rigid, vibration‑resistant bus connection that stays seated in equipment with fans, motors, or HVAC vibration.
• Thermal‑magnetic trip unit delivers stable, repeatable protection—overloads are met with a controlled response, while short circuits trip quickly to minimize damage.
• OEM‑compatible designed to work with matching OEM load centers and panelboards for straightforward replacement or upgrade.
• Three‑pole protection ideal for three‑phase circuits, making it well suited for commercial and light industrial panels.

Why this breaker stands out

When reliability matters, the FD3070 delivers with a secure bolt‑on connection that reduces the risk of loose bus bars and intermittent faults. The thermal‑magnetic trip unit combines fast fault clearing with predictable behavior under overloads, helping protect wiring insulation and downstream devices. Its OEM compatibility means you can integrate this breaker into existing panelboards and loadcenters without compatibility hiccups, keeping installation clean, compliant, and easy to service.

Ideal use scenarios

• Upgrading residential or light commercial panels that require a robust 3‑pole protection solution
• Retrofits where a bolt‑on breaker is preferred for secure mounting in vibrational environments
• New installations in panelboards and loadcenters that demand reliable overcurrent and short‑circuit protection for three‑phase circuits

Practical tips

• Verify that your panelboard supports bolt‑on breakers and three‑pole configurations before installation.
• Follow proper mounting procedures to ensure a solid bus connection and optimal trip performance.
• In commissioning, test the trip function to confirm stable overload protection and rapid short‑circuit clearing.
