Product FAQs
4 answersHow should I use the 600VAC rating when selecting this breaker frame?
The 600VAC rating sets the voltage limit for AC circuit selection. Compare the circuit's operating voltage with this rating when choosing the frame.
How are the poles and neutral handled in a three-phase installation?
The frame has three poles for the three phase conductors. A neutral connection is not applicable, so the three poles are used for phase conductors rather than a neutral.
What conductor sizes can I terminate in the lugs?
The lug terminals accept conductor sizes from 3/0 AWG through 500 kcmil. Use this range when selecting conductors for termination, while also sizing them for the circuit's electrical requirements.
What does the HACR rating mean for an HVAC application?
HACR means heating, air conditioning and refrigeration. The HACR rating is relevant when selecting circuit protection for equipment that calls for a HACR-rated breaker.
