Product FAQs
6 answers
How do I use the voltage ratings when selecting this frame?
The voltage ratings are 480VAC and 600VAC. Match the rating to the circuit voltage, and evaluate interrupting capacity at that voltage separately.
What available fault current can this frame accommodate at 480VAC?
The interrupting rating is 35kA at 480VAC. For a 480VAC application, the available fault current at the installation point must not exceed 35kA.
How are the three poles used in a three-phase circuit?
The three poles serve the three phase conductors. Neutral connection is not applicable, so plan neutral handling separately from this frame.
What does bolt-on mounting mean for installation?
Bolt-on mounting uses bolted connections rather than plug-in engagement. Plan installation around securing those connections.
What conductor-size limit should I use for the lug terminals?
The lug terminals have a maximum wire size of 500 kcmil. Keep conductor selection within that terminal limit while sizing conductors for the circuit.
What does the 800A rating mean for the General Electric THKM836F000?
The 800A rating is the frame amperage. Choose this frame-only product when planning a breaker assembly that calls for an 800A frame, rather than treating it as a complete circuit breaker.
