Product FAQs
6 answersDoes the RD316T36W include terminal lugs out of the box?
No. The 'W' suffix in the catalog number indicates this breaker is supplied without terminals. You must purchase lug kits separately or use rear connectors for busbar mounting.
Which lug kit is required for cable connections on the RD316T36W?
You will need the TA1600RD lug kit for standard cable terminations. This kit accepts four 500 to 1000 kcmil aluminum or copper conductors per phase.
What protection functions are included in the T36W trip unit?
The T36W designation means this breaker is equipped with a Digitrip 310 RMS electronic trip unit featuring fully adjustable LSIG functions: Long-Time, Short-Time, Instantaneous, and Ground-Fault protection.
Does this breaker provide ground-fault protection for equipment?
Yes, the 'G' in the LSIG trip unit provides adjustable ground-fault protection. This is often required by the NEC for 1000A or larger services operating at 480V.
What type of distribution equipment accepts the RD316T36W?
This R-Frame breaker is designed to bolt directly into Eaton Series C panelboards, switchboards, and motor control centers.
Is the RD316T36W a direct replacement for older Cutler-Hammer R-Frame breakers?
Yes, it directly replaces older Cutler-Hammer and Westinghouse Series C RD-frame breakers with the same specifications, as they share the same physical footprint and bolt-on mounting configuration.
