Product FAQs
8 answersWhat current rating should I use when selecting the Siemens HPD63B140?
The Siemens HPD63B140 has a rated current of 1400A. Use that rating when coordinating breaker selection with the circuit load and conductor ampacity.
What system voltages can this breaker be selected for?
The voltage ratings are 240VAC, 480VAC, 600VAC and 500VDC. Select according to both the system voltage and whether the circuit is AC or DC.
How do I check the interrupting rating against available fault current?
The UL 489 interrupting ratings are 65kA at 480VAC and 50kA at 600VAC. At the applicable voltage, available fault current at the installation point must not exceed the corresponding interrupting rating.
How does the thermal-magnetic trip protect the circuit?
The thermal-magnetic trip combines thermal response to sustained overloads with magnetic response to short-circuit current. Its LI function covers long-time and instantaneous protection, making both overload and short-circuit behavior relevant to selection.
Which trip settings can I adjust?
The thermal trip is fixed, while the magnetic trip is adjustable. Use the magnetic adjustment to coordinate instantaneous pickup with circuit requirements; the thermal overload setting remains fixed.
Is this a three-pole breaker for a three-phase circuit?
Yes, it is a three-pole breaker for three-phase applications. Choose it when the circuit requires a breaker that opens all three phase conductors together.
What conductor sizes and terminal connections should I plan for?
The conductor range is 300-600 MCM, with lug connections on both the line and load sides. Plan conductor sizing and termination work around that range and connection type.
How much depth should I account for in the installation layout?
The breaker depth is 6.19 in. Account for that dimension in the equipment layout, along with the space needed for conductor routing and termination work.
