Eaton BAB1070 - 70 A, 120 V, 1-Pole Bolt-On Circuit Breaker | AmpState

Meet the Eaton BAB1070 — a 70A, 120V, 1-pole bolt-on molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built to endure in demanding environments, this device combines a rugged bolt-on mounting with precise protection, making it a trusted choice for electrical professionals and serious DIY projects alike.

What makes this breaker stand out

• Bolt-on mounting: delivers a rigid, vibration-resistant bus connection for reliable performance in panels and load centers.
• Thermal-magnetic trip unit: provides stable, repeatable protection by combining slower, temperature-based overload response with fast magnetic trip for short circuits.
• 70A / 120V, 1-pole: ideal for dedicated single-phase circuits that demand solid protection without unnecessary complexity.
• OEM-compatible: designed to work with matching Eaton OEM load centers and panelboards, ensuring proper fit, coordination, and code-compliant safety margins.
• Versatile by design: suitable for residential, commercial, and light industrial applications where reliable branch-circuit protection is essential.

Practical benefits and use cases

Use the BAB1070 when you need robust protection for a high-current branch circuit within a panelboard or load center. The bolt-on design minimizes loose connections that can occur in vibration-prone environments like equipment rooms or industrial settings, helping prevent nuisance trips and maintaining system integrity. This breaker excels in single-hot-wire applications where a dedicated 70A protection point is required, paired with a neutral as dictated by the panel's layout.
