Siemens HLD63F600 is a Sentron circuit breaker frame with a 600A HLD frame, 3 poles and a 600VAC voltage rating. Interrupting ratings are 35kAIC at 600V and 65kAIC at 480V. It has unit mounting, line and load side lugs, and UL and IEC approvals. The frame measures 7.5 in wide by 11 in high. Trip unit not included (frame only).
What system voltage should I check before selecting this frame?
The voltage rating is 600VAC. Check the circuit's AC voltage against this rating, and use the interrupting rating applicable to that voltage when evaluating available fault current.
How do I evaluate the interrupting rating against available fault current?
The interrupting rating is 35kAIC at 600V and 65kAIC at 480V. Available fault current at the installation point must not exceed the interrupting rating applicable to the circuit voltage.
How does the three-pole construction guide circuit selection?
This is a three-pole frame. Use the pole count when selecting equipment for a circuit that requires three poles of interruption.
What conductor sizes and materials can I use at the lugs?
The line and load sides have lug terminals accepting copper from AWG 3/0 to 500KCM and aluminum from AWG 4/0 to 500KCM. Check both conductor material and size when planning the terminations.
What dimensions should I account for in the installation layout?
The frame is 11 in high and 7.5 in wide. Use these dimensions when planning its position and the space needed for installation work.
