Eaton JD3250 - 250 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton JD3250 is a 3-pole bolt-on molded case circuit breaker engineered to deliver dependable branch circuit protection for panelboards and loadcenters. With a 250A rating and a 600V capacity, this unit is built to handle demanding commercial and light industrial applications while fitting neatly into residential panel installations that demand robust protection.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection that stays tight under demanding operating conditions, reducing the risk of loose connections and nuisance trips.
• Thermal-magnetic trip unit combines thermal overload sensing with magnetic instantaneous trip for stable, repeatable protection against both overcurrent and short circuits.
• 3-pole, 250A, 600V configuration protects all three hot conductors in a three-phase system, making it ideal for panels that require coordinated, full-system protection.
• OEM-compatible design matches Eaton’s own loadcenters and panelboards, simplifying replacements, upgrades, and field retrofits without compatibility concerns.
• Versatile for multiple environments suited for residential, commercial, and light industrial installations, whether used as main protection in a panel or as a critical branch-circuit safeguard.
