Eaton BD2040 - Circuit Breaker | AmpState

Eaton BD2040 molded case circuit breaker from AmpState is engineered to deliver reliable, repeatable protection for branch circuits in panelboards and loadcenters. Its compact footprint makes the most of precious panel space, while a sophisticated thermal-magnetic trip unit provides stable protection against both overloads and short circuits. If you’re upgrading a panel or designing a compact, dependable electrical system, the BD2040 is built to perform without crowding your enclosure.

Key differentiators that matter in the real world

• Space-efficient molded-case design preserves panel capacity, enabling safer, neater installations in tight panels and multi-circuit configurations.
• Thermal-magnetic trip unit offers fast, predictable response to faults and overloads, minimizing nuisance trips and protecting wiring and devices with consistent performance over time.
• OEM compatibility is a practical advantage: designed to work with matching Eaton OEM loadcenters and panelboards, ensuring seamless integration, reliable mounting, and straightforward ordering when you service or replace components.
• Versatility across sectors suitable for residential, commercial, and light industrial applications—so you can standardize on one trusted protection device across multiple projects.

What problems does it solve?

• Prevents damage from overcurrent and short circuits in branch circuits, protecting wiring insulation, devices, and downstream equipment.
• Reduces downtime with predictable, resettable protection that you can count on during routine operations and fault conditions alike.
• Minimizes panel crowding through its compact design, making room for conductors, terminations, and diagnostic accessories without sacrificing protection quality.

Ideal use scenarios

• New panel installations where space efficiency and reliable protection are paramount.
• Panelboard or loadcenter upgrade projects requiring compatible, readily available replacement breakers.
• Residential distribution panels in multi‑circuit homes, small commercial spaces, or light industrial setups where robust protection is essential.
• Maintenance and service work where a trusted, OEM-compatible solution streamlines part sourcing and installation.
