Product FAQs
7 answersHow should I use the 90A rating when selecting the Siemens HFXD63B090?
The 90A rated current is the starting point for coordinating the breaker with the circuit load and conductor protection requirements. Evaluate that current rating separately from the voltage and interrupting ratings.
What voltage ratings should I check for an AC or DC application?
The breaker is rated 600VAC and 500VDC. Select against the rating for your circuit's current type and voltage, and evaluate interrupting capacity separately.
Is this a three-pole breaker for a three-phase circuit?
This is a three-pole, three-phase molded case circuit breaker. Use the pole count and phase configuration when selecting protection for a three-phase circuit, alongside the current, voltage and interrupting ratings.
What protection does the thermal-magnetic LI trip provide?
The LI trip provides long-time and instantaneous overcurrent protection. Its thermal element responds to sustained overloads, while its magnetic element responds rapidly to high-current faults.
Which trip settings can I adjust?
The thermal trip is fixed, and the magnetic trip is adjustable. Adjustment applies to the magnetic pickup for high-current faults, so select that setting as part of the circuit's protection coordination.
How are the load conductors connected?
The load-side connection uses a lug. Plan the outgoing conductor termination around that connection method.
How does the 65kAIC at 480V rating affect selection?
At 480V, the available fault current at the installation point must not exceed the breaker's 65kAIC interrupting rating. Compare that rating with the available fault current when selecting the breaker.
