Product FAQs
9 answersCan I adjust the trip settings on the Siemens 3VA4145-5ED34-0AA0?
This 45A breaker has fixed thermal and fixed magnetic trip settings. Thermal protection responds to sustained overloads, while instantaneous magnetic protection responds to short circuits. Choose it when fixed settings suit the circuit's protection requirements.
Which system voltages can this breaker be used on?
The voltage ratings are 240VAC, 480Y/277VAC, 480VAC, 600Y/347VAC and 250VDC. Match the rating to the system voltage and AC or DC service. The slash ratings apply to wye systems and express line-to-line and line-to-neutral voltage.
How do I select this breaker based on available fault current?
The interrupting ratings are 35kAIC at 480Y/277VAC and 18kAIC at 600Y/347VAC. At the applicable voltage, select the breaker so its interrupting rating meets or exceeds the available fault current at the installation point.
What conductors can I terminate at the load-side lug?
The conductor range is 8 AWG through 3/0 AWG for copper or aluminum, with a load-side lug connection. Choose a conductor within that range while meeting the circuit's ampacity requirements.
What does the HACR rating mean when selecting this breaker?
HACR means heating, air conditioning and refrigeration. The rating supports selection for those equipment circuits; match the breaker selection to the equipment's electrical requirements.
Why does the HID rating matter for lighting circuits?
HID means high-intensity discharge lighting. The HID rating addresses this type of lighting application, making it relevant when selecting protection for circuits serving HID loads.
What dimensions should I use when planning the breaker layout?
The breaker is 5.09 in high, 3 in wide and 2.96 in deep. Use these dimensions to plan its physical location and mounting space in the equipment layout.
What operating temperature range should I consider for the installation?
The operating temperature range is -25C to 70C. Compare the expected temperature at the breaker location with this range when planning the installation.
Can this breaker be reverse fed?
Yes. Its reverse-feed feature allows the incoming power connection at the load side when the installation requires that feed direction.
