Eaton HFD3150 - 150 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Eaton HFD3150 is a 150 A, 600 V, 3-pole bolt-on molded case circuit breaker designed to deliver reliable branch circuit protection and short-circuit interruption in panelboards and load centers.

• Secure bolt-on mounting: creates a rigid, vibration-resistant bus connection that stays tight through routine panel servicing and equipment start-ups.
• Thermal-magnetic trip unit: provides stable, repeatable protection by combining thermal overload sensing with magnetic short-circuit tripping for fast response to high-energy faults.
• 3-pole configuration: ideal for 3-phase systems, ensuring synchronized disconnection across all conductors to protect equipment and wiring.
• OEM-compatible design: engineered to pair with matching Eaton OEM load centers and panelboards for a straightforward upgrade or replacement path.
• Broad application range: suitable for residential, commercial, and light industrial environments where dependable overcurrent protection is a must.

Why this matters in real-world setups:

• In busy commercial spaces or equipment rooms, the bolt-on mounting minimizes movement and wear on the bus connection, reducing nuisance trips and downtime.
• The thermal-magnetic trip unit balances protection against nuisance tripping with rapid, decisive action during short-circuit events, helping safeguard wiring and connected loads.
• Three-pole protection is essential for any three-phase circuit, ensuring that all phases trip together to prevent damage and uneven load conditions.
• When upgrading legacy panels or expanding a system, the HFD3150 offers a reliable, compatible option that maintains consistent protection characteristics with other Eaton devices.
