Product FAQs
5 answersWhat is required to complete the Siemens MD63F800 breaker assembly?
The Siemens MD63F800 is a circuit breaker frame. A trip unit and line and load terminals are required to complete the assembly for circuit protection and conductor connections.
How should I use the 800A frame rating when selecting this breaker?
The 800A rating describes the frame amperage. Use it for frame selection, and select the required trip unit according to the circuit's overcurrent protection requirements.
How do I check the interrupting rating for an AC application?
The frame is rated for 600VAC, with interrupting ratings of 65kA at 240VAC, 50kA at 480VAC and 25kA at 600VAC. Compare available fault current at the installation point with the interrupting rating at the applicable voltage; it must not exceed that rating.
When should I choose a three-pole breaker frame?
Choose this three-pole frame when the circuit design requires three poles for circuit interruption. Pole count is a separate selection requirement from voltage, frame amperage and interrupting rating.
Does this frame carry UL and CSA approvals?
This frame is UL Listed and CSA Certified. These approvals support selection for projects that require UL listing or CSA certification for the breaker frame.
