Eaton EHD1070L - 70 A, 277 V, 1-Pole Circuit Breaker | AmpState

Eaton EHD1070L — a 70A, 277V, 1-pole molded case circuit breaker designed for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers.

Key benefits that matter in real-world panels

• Space-efficient molded case design: minimizes footprint and optimizes panel layout, making room for future circuits without expanding the enclosure.
• Thermal-magnetic trip unit: combines temperature-based and magnetic sensing to deliver stable, repeatable protection during normal operation and during high-current faults, reducing nuisance trips while ensuring rapid fault clearance when needed.
• OEM-compatible: specifically engineered to be compatible with matching Eaton load centers and panelboards, ensuring alignment with your existing protection strategy and component family.
• Versatile across environments: ideal for residential, commercial, and light industrial applications where reliable 277V distribution and robust overcurrent protection are required.
• Robust 70A protection: provides reliable safeguarding for feeders and branch circuits, preventing damage from overcurrent conditions while enabling safe, predictable operation.

Use it as a drop-in replacement within matching Eaton panelboards and load centers to maintain consistent protection characteristics across your installation. The EHD1070L is well-suited for feeders to equipment rooms, lighting branches, or receptacle circuits that demand predictable trip behavior and durable performance.

Why this Eaton breaker stands out

Beyond basic specs, the EHD1070L delivers a cohesive protection strategy when paired with other Eaton components. The molded case design reduces panel clutter and supports efficient wire routing. The thermal-magnetic trip unit provides a balanced response that protects conductors and devices without unnecessary interruptions. In environments where electricians rely on OEM compatibility for serviceability and lifecycle, this breaker offers straightforward replacement with preserved trip characteristics and electrical coordination.

Tips for installation and compatibility

Ensure your panelboard or load center is designed for Eaton EHD series molded case breakers and that the EHD1070L’s 70A, 1-pole, 277V specs align with the circuit you’re protecting. When in doubt, verify the panel’s listed compatible breaker list and confirm that the trip curve and coordination with adjacent devices meet your protection plan. As with all electrical work, install by qualified personnel and follow local codes and manufacturer guidelines.
