Product FAQs
5 answersWhat does the 250A frame rating mean for the Siemens HHFD63F250?
The 250A rating describes the frame amperage class. Use this rating when selecting the frame size for a circuit breaker assembly.
How should I use the 600VAC voltage rating when selecting this frame?
The 600VAC rating sets the voltage limit for selection on an AC system. Select it for a system voltage at or below that rating, and evaluate the interrupting rating separately at the operating voltage.
How do I evaluate the 100kAIC interrupting rating at 480V?
At 480V, the interrupting rating is 100kAIC. Compare that rating with the available fault current at the installation point; the interrupting rating must be at least as high as the available fault current.
What does bolt-on mounting mean for installation?
Bolt-on mounting uses bolted fastening for installation. Plan for a bolted installation rather than a plug-in mounting method.
When should I choose a 3-pole circuit breaker frame?
Choose a 3-pole frame when the circuit breaker assembly needs to interrupt three circuit conductors together. Pole count should match the circuit's switching and protection requirements.
