Product FAQs
5 answers
Can I use the Eaton JD3200 to replace an older Westinghouse JD3200 breaker?
Yes, the Eaton Series C JD3200 is a direct mechanical and electrical replacement for legacy Westinghouse and Cutler-Hammer JD3200 circuit breakers.
Are there higher interrupting rating options for this frame size?
Yes. If your electrical system requires higher fault protection, the HJD3200 and JDC3200 models are direct J-frame upgrades that offer higher short-circuit interrupting capacities while maintaining the exact same physical footprint.
Can the JD3200 be installed in reverse-feed applications?
Yes, this breaker is rated for reverse-feed use. Line power can be connected to either the top or bottom terminals safely without impacting the thermal-magnetic trip unit functionality.
What is the purpose of the adjustable magnetic trip on this breaker?
The adjustable magnetic dial allows installers to set a precise instantaneous short-circuit response threshold. This is particularly useful for avoiding nuisance trips caused by the high inrush currents typical of motor start-ups.
Is the JD3200 certified for use with HVAC equipment?
Yes, this circuit breaker is HACR rated, meaning it is safety certified for the specific protection requirements of commercial heating, air conditioning, and refrigeration equipment circuits.
