Product FAQs
8 answersAre lugs included with the HMXD63B600 circuit breaker?
No, the HMXD63B600 does not include lugs from the factory. Compatible lug kits for this MD frame breaker include the TA2K500 (2-barrel) and TA3K500 (3-barrel), which accept both copper and aluminum conductors.
What is the difference between the MXD63B600 and the HMXD63B600?
The HMXD63B600 is the high-interrupting capacity version of the standard MXD63B600. The HMXD63B600 provides a 65kAIC rating at 480V, whereas the standard MXD63B600 is rated for 50kAIC at 480V. Both share the same physical MD frame dimensions and accept the same accessories.
Is the HMXD63B600 rated for 100 percent continuous operation?
No, the standard HMXD63B600 is rated for continuous operation at 80 percent of its 600A capacity. For applications requiring a 100 percent continuous current rating, the HMXD63B600H variant must be used.
What NEMA enclosures are compatible with the HMXD63B600?
The HMXD63B600 can be installed in Siemens MD frame enclosures, such as the MND61 for NEMA 1 indoor applications or the MND63 for NEMA 3R outdoor applications.
How is the trip unit on the HMXD63B600 adjusted?
The HMXD63B600 features a thermal-magnetic trip unit with a fixed thermal setting for long-time overload protection and an adjustable magnetic setting for instantaneous short-circuit protection. The magnetic trip can be adjusted using the dial on the front of the breaker.
Can I add a shunt trip or auxiliary switch to the HMXD63B600?
Yes, the HMXD63B600 accepts standard Siemens Sentron MD frame internal accessories, including shunt trips, auxiliary switches, and undervoltage releases. These are typically installed under the front cover of the breaker.
Can the trip unit on the HMXD63B600 be swapped or upgraded?
No, the HMXD63B600 is a factory-assembled breaker with a non-interchangeable trip unit. If a different trip rating or electronic trip function is required, the entire breaker must be replaced.
Is the HMXD63B600 suitable for reverse feed applications?
Yes, because the HMXD63B600 features a non-interchangeable trip unit, it is suitable for reverse feed applications in accordance with UL 489 standards.
