Eaton JD3070X - 70 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton JD3070X is a 70A, 600V, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and loadcenters. Built for serious electrical protection, it disconnets power quickly on fault conditions while standing up to the vibration and mechanical demands of real-world installations.

• Bolt-on mounting for a secure connection — provides a rigid, vibration-resistant bus connection that stays tight through operation and transport.
• Thermal-magnetic trip unit for stable protection — combines precise thermal overload sensing with fast magnetic tripping for short circuits, delivering repeatable protection characteristics across the operating range.
• OEM-compatible for easy replacements — designed to be compatible with matching OEM load centers and panelboards, simplifying upgrades, replacements, and service upgrades.
• Three-pole design for comprehensive protection — appropriate for three-phase distributions, ensuring all phases are simultaneously protected and de-energized in fault conditions.
• Versatile for multiple environments — suitable for residential, commercial, and light industrial applications where reliable circuit protection is essential.

The JD3070X stands out by pairing a robust bolt-on mounting approach with a precise thermal-magnetic trip mechanism, reducing nuisance trips while delivering fast, predictable clearing of faults. This makes it a practical choice for panelboard builders, electricians upgrading service equipment, and facilities teams maintaining reliable electrical distribution systems.
