Product FAQs
6 answersCan the HMDL3500 replace older Westinghouse circuit breakers?
Yes. The Eaton Series C M-frame is a direct replacement for legacy Westinghouse MA, MD, HMA, MC, and HMC frame circuit breakers. Verify your busbar connections and lug requirements before installation.
What is the difference between the Eaton MDL3500 and HMDL3500?
The H in HMDL designates a high interrupting capacity. The HMDL3500 is rated for 65kAIC at 480VAC, whereas the standard MDL3500 is rated for 50kAIC at 480VAC.
What wire sizes are compatible with the standard lugs on the HMDL3500?
The standard feed-thru lugs accept two 1 AWG to 500 kcmil aluminum or copper conductors per phase.
What enclosures are designed to accept the HMDL3500 breaker?
This M-frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers.
Does the HMDL3500 provide ground fault protection?
No. This breaker features an LI (Long-Time and Instantaneous) thermal-magnetic trip unit, which provides overload and short-circuit protection but does not include ground fault sensing.
Are the trip settings adjustable on the HMDL3500?
No. This specific breaker features a fixed thermal and fixed magnetic trip unit. It does not offer adjustable long-time or instantaneous pickup settings.
