Eaton HJD3250 - 250 A, 600 V, 3-Pole Circuit Breaker | AmpState

The Eaton HJD3250 is a rugged, three-pole molded case circuit breaker engineered to deliver reliable branch circuit protection for panelboards and loadcenters. With a 250 A rating and a 600 V maximum, this breaker is built to handle demanding commercial and light industrial environments while staying compact enough to maximize panel space. Sold through AmpState, it’s a trusted choice for upgrading or expanding protected electrical distribution.

• Compact molded case design: Optimizes panel space without compromising protection, making it easier to fit into dense electrical rooms and retrofit projects.
• Thermal-magnetic trip unit: Provides stable, repeatable protection by combining thermal overload sensing with magnetic short-circuit protection for fast, decisive trips during faults.
• 3-pole configuration for 600 V systems: Ideal for three-phase distribution in commercial and light industrial applications, supporting up to 600 V and 250 A per circuit.
• OEM panel compatibility: Designed to align with matching OEM loadcenters and panelboards, ensuring proper fit, mounting, and protective coordination with existing systems.
• Versatile application range: Suitable for residential, commercial, and light industrial environments where dependable overcurrent and short-circuit protection is critical.

Why this matters in real-world setups: in a busy electrical room, you need protection that won’t drag down panel density or complicate maintenance. The HJD3250’s compact form factor frees space for feeders and bus-tied circuits, while its thermal-magnetic trip offers predictable responses—preventing nuisance trips and delivering rapid separation of faulted circuits when faults occur. This makes it a practical choice for service panels, distribution panels, and retrofit projects where performance and space efficiency are paramount.
