Product FAQs
6 answersWhat equipment is the HMA3600 designed to fit?
This bolt-on MCCB mounts into legacy Westinghouse and Eaton panelboards and switchboards. It is also suitable for use with Pow-R-Way III aluminum and copper busway systems.
What is the modern replacement for the legacy HMA3600 breaker?
For modern retrofits, the legacy HMA frame is typically replaced by the Eaton HMDL3600 Series C molded case circuit breaker.
What are the terminal specifications for this 600A breaker?
The breaker comes complete with line and load lugs that accept two 250 to 500 kcmil aluminum or copper conductors per phase.
What does the adjustable magnetic trip function allow on this breaker?
The thermal-magnetic trip unit features a fixed thermal element for overload protection and an adjustable magnetic element. This allows electricians to customize the instantaneous short-circuit trip response based on specific load requirements.
What makes the HMA3600 suitable for high fault current systems?
As a Mark 75 series breaker, it features a high interrupting capacity, safely clearing faults up to 65kA at 240VAC and 35kA at 480VAC to protect downstream industrial equipment.
Is the HMA3600 rated for direct current applications?
Yes, this breaker is rated for 250VDC systems with a 20kA interrupting capacity, making it suitable for specific industrial DC power distribution networks.
