Product FAQs
7 answersWhat current rating should I use when selecting the Siemens HMXD63B700?
The Siemens HMXD63B700 is rated 700A. Use that rating when coordinating breaker selection with the circuit load and conductor protection requirements.
Can this breaker be selected for AC or DC circuits?
Its rated voltages are 240VAC, 480VAC, 600VAC and 500VDC. Select the voltage rating that matches the circuit, keeping AC and DC ratings separate.
How do I check its interrupting rating against available fault current?
The UL 489 interrupting ratings are 65kA at 480VAC and 50kA at 600VAC. At the applicable voltage, the available fault current at the installation point must not exceed that interrupting rating.
What does the three-pole configuration mean for a three-phase circuit?
This is a three-pole breaker for three-phase use, giving each phase conductor a breaker pole. Use that configuration when planning protection for the three phase conductors.
How does the thermal-magnetic LI trip work, and what can I adjust?
The LI thermal-magnetic trip provides long-time overload protection and instantaneous short-circuit protection. The thermal setting is fixed, while the magnetic setting is adjustable so its pickup can be selected as part of protection coordination.
Are cable lugs included for conductor termination?
No Lugs means cable lugs are not included with the breaker. Account for conductor termination hardware when planning the installation.
What mounting format and dimensions should I account for?
This MD-Frame breaker uses unit mounting and measures 9.00 in wide by 6.00 in deep. Use the mounting format and these dimensions when planning the mounting location and installation layout.
