Eaton JDB3125 is a 125 A, 600 V, 3-Pole molded case circuit breaker designed to safeguard branch circuits in panelboards and loadcenters. Its compact molded case design maximizes panel space while delivering robust overcurrent and short-circuit protection.
The thermal-magnetic trip unit provides stable, repeatable protection performance across a wide range of operating conditions, with fast response to overcurrent events to minimize equipment damage and downtime.
Designed for OEM compatibility, the JDB3125 matches Eaton and other OEM loadcenters and panelboards, simplifying installation and future service. This means you can confidently upgrade, replace, or service panels with a breaker that fits the same footprint and protective characteristics.
Ideal for residential, commercial, and light industrial applications, this 3-pole breaker protects multiple conductors in one device, making it a practical choice for feeders, distribution circuits, and motor loads where three-pole protection is needed.
