Description
Part of the legacy J-frame series, this 225-amp thermal-magnetic breaker provides essential overcurrent protection for commercial and industrial facilities. It integrates seamlessly into older Westinghouse panelboards, switchboards, and motor control centers. Featuring a 35kAIC rating at 480VAC and adjustable magnetic trip settings, it offers robust performance for demanding electrical systems. This unit serves as an exact match before transitioning to the newer JD3225 replacement model.Specifications

Product FAQs
5 answersWhat types of enclosures and equipment are compatible with the J3225?
This legacy J-frame breaker is designed to integrate seamlessly into older Westinghouse panelboards, switchboards, and motor control centers. It uses a standard bolt-on mounting configuration.
Is there a newer replacement model for the legacy J3225 circuit breaker?
Yes, while the J3225 serves as an exact match for older Westinghouse installations, Eaton has transitioned the J-frame series to the newer JD3225 replacement model for modern applications.
Are lugs included with the J3225, and what wire sizes do they accept?
Yes, the breaker comes equipped with standard lugs that accommodate either aluminum or copper conductors from 4 AWG to 350 kcmil. Always verify the required torque values specified on the breaker faceplate or enclosure label before terminating the conductors.
What does the adjustable magnetic trip setting on the J3225 allow me to do?
While the thermal overload protection is fixed, the adjustable magnetic trip allows you to set the instantaneous short-circuit response. This is critical for preventing nuisance tripping from motor inrush currents and for achieving proper selective coordination with downstream breakers.
Is the J3225 suitable for direct current (DC) applications?
Yes, it carries a 250 VDC rating with a 10 kA interrupting capacity. When installing in DC systems, ensure the wiring method complies with manufacturer guidelines, which may require wiring multiple poles in series depending on the system voltage and grounding configuration.
