Eaton BAB1080 - 80 A, 120 V, 1-Pole Bolt-On Circuit Breaker | AmpState

The Eaton BAB1080 is a purpose-built solution for dependable branch circuit protection in panelboards and loadcenters. Engineered as a 1-pole, bolt-on molded case circuit breaker rated at 80A and 120V, it delivers precise, repeatable protection where reliability matters most—in residential panels, commercial distribution, and light industrial installations. <-- Key benefits and why it matters -->

• Secure bolt-on mounting: The bolt-on design creates a rigid, vibration-resistant connection to the bus, reducing the risk of loose contacts that can lead to nuisance trips or degraded protection in environments with movement or vibration.
• Thermal-magnetic trip unit: Combines thermal overload sensing with magnetic short-circuit protection for fast, predictable trips. This means the breaker responds consistently to overloads and severe faults, protecting downstream wiring and devices while minimizing unnecessary outages.
• Molded-case durability: Built as a molded case breaker, it offers robust durability for daily operation and ease of integration into existing panelboard architectures.
• OEM-compatible and versatile: Designed to work with matching Eaton OEM loadcenters and panelboards, ensuring a cohesive protection scheme across your electrical distribution system.
• Ideal for a range of settings: Suitable for residential, commercial, and light industrial applications—where reliable 80A, 120V single-pole protection is required for heavier circuits or dedicated loads.

The Eaton BAB1080 is more than just a breaker—it’s a core component of a safe, scalable electrical system. Its bolt-on mounting is particularly advantageous in installations where robust mechanical connections are critical, such as panelboards in busy service areas or equipment rooms on commercial floors. The combination of a thermal and magnetic trip mechanism delivers a dependable response across temperature variations and electrical transients, helping to maintain continuity for non-fault conditions while providing swift protection when faults occur.

Where this breaker shines

• Updating or upgrading an existing panelboard with a trusted, compatible 80A, 120V 1-pole solution
• Providing dedicated protection for heavy-load branch circuits in residential basements or garages, small offices, or retail spaces
• Integrating into light industrial electrical setups where reliable, repeatable short-circuit protection is essential

Compared to other mounting styles, the bolt-on approach reduces the risk of contact deterioration from repeated insertions or thermal cycling. It also supports a long service life in environments where panel enclosures experience vibration or movement, such as on loading docks, workshop areas, or back rooms with heavy equipment.
