Eaton EDB3150 - 150 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Eaton EDB3150 is a 150A, 240V, 3-pole bolt-on molded case circuit breaker designed to shield panelboards and load centers from overcurrent and short-circuit events. Built for reliability in residential, commercial, and light industrial applications, this breaker keeps critical electrical circuits safe and serviceable.

• Bolt-on mounting secures the breaker to the panel bus connection with a rigid, vibration-resistant fit, reducing loosening risk in environments with equipment noise or movement.
• Thermal-magnetic trip unit delivers stable, repeatable protection—thermal element handles overloads, magnetic element provides instantaneous trip for short circuits, helping protect wiring and devices.
• OEM-ready compatibility pairs with matching Eaton OEM load centers and panelboards, ensuring proper fit, correct trip coordination, and straightforward installation.
• Three-pole, 240V design supports three-phase distribution in commercial or industrial panels, enabling clean, balanced protection across all phases.
• Molded case construction provides robust insulation and durable performance in demanding electrical environments.

Use this breaker when upgrading or expanding a panelboard where a 150A, 3-pole protection device is needed—such as main or feeder circuits in small to mid-size commercial spaces or service panels in light industrial settings. Its bolt-on design makes field installation straightforward on compatible bus systems, and the 240V rating supports line-to-line protection across three phases.

With the Eaton EDB3150, you get predictable protection curves, easier maintenance, and vendor-controlled compatibility. You’ll be able to quickly isolate a fault, protect conductors from overheating, and reduce nuisance trips by using a device calibrated for your panel's design, all while maintaining code-compliant safety margins.
