Product FAQs
5 answersHow should I use the 800A rating when selecting the Siemens / ITE HM3F800?
The 800A rating is the breaker's rated current, not its fault-interrupting capacity. Use it when coordinating the breaker with the circuit load and conductor ampacity.
What does the 600VAC voltage rating mean for circuit selection?
Select the breaker for a circuit whose AC voltage does not exceed 600VAC. Evaluate interrupting capacity separately at the circuit's operating voltage.
How do I evaluate the 65kA interrupting rating at 480VAC?
At 480VAC, the breaker has a 65kA interrupting rating. Compare that rating with the available fault current at the installation point, which must not exceed the breaker's interrupting capacity.
When should I choose this three-pole breaker?
Its three-pole configuration serves a three-phase circuit, with one breaker pole for each phase conductor. Choose it when the circuit design requires three-phase protection through three poles.
What does bolt-on mounting mean for installation?
Bolt-on mounting uses bolted attachment to secure the breaker. Plan installation around fastening and tightening those mounting connections.
