Product FAQs
6 answersHow do I select the current setting for the Siemens 3VA6440-5HL31-2AA0?
This 400A breaker has an adjustable trip range of 160-400A. Select a setting within that range that coordinates with the circuit's conductor ampacity, load requirements and protection requirements.
Which AC voltage ratings can I use when selecting this breaker?
The rated voltages are 240VAC, 480VAC and 600VAC. Match the circuit voltage to the appropriate voltage rating, and evaluate interrupting capacity separately for the installation.
What protection does the electronic trip provide?
The electronic trip provides long-time and instantaneous protection, with adjustable thermal and magnetic settings. Long-time protection responds to sustained overcurrent, while instantaneous protection responds to high-current faults without an intentional delay; use these functions when planning protection coordination.
What does fixed mounting mean for installation planning?
Fixed mounting means the breaker is installed in a stationary position rather than used as a drawout device. Plan installation and maintenance around that fixed arrangement.
How does the 35kAIC rating at 480V affect breaker selection?
At 480V, the breaker has a 35kAIC interrupting rating. Compare the available fault current at the installation point with that rating and select the breaker only when the available fault current does not exceed its interrupting capacity.
Why does the 3-pole configuration matter when selecting this breaker?
Pole count determines the number of conductors switched together. This breaker has 3 poles and a 3-phase rating, so include both in circuit-protection selection alongside current, voltage and interrupting ratings.
