Product FAQs
7 answersHow should I use the 300A rating when selecting the Siemens 3VA5330-6EC61-0AA0?
The 300A rated current is a starting point for selecting circuit protection. Coordinate the circuit load and conductor ampacity with this rating and applicable installation requirements.
Can I select this breaker for an AC or DC circuit?
The breaker is rated 600VAC and 250VDC. Match the voltage rating to both the circuit voltage and whether the circuit uses AC or DC.
How do I select the correct interrupting rating for my installation?
Compare available fault current at the installation point with the interrupting rating for the circuit voltage: 25kA at 600V, 65kA at 480V, or 100kA at 240V. Available fault current must not exceed the applicable interrupting rating.
What does the thermal-magnetic trip do, and which setting can I adjust?
The thermal element responds to sustained overloads, while the magnetic element provides instantaneous response to high fault current. The thermal setting is fixed; the magnetic setting is adjustable so its pickup can be coordinated with circuit requirements.
When should I choose the two-pole version?
Choose this two-pole breaker when the circuit design requires protection of two circuit conductors. Pole count should follow the circuit arrangement, not just its current rating.
What dimensions should I account for when laying out the installation?
Account for a height of 9.76 in, a width of 5.43 in and a depth of 4.33 in when allocating installation space. Include these dimensions in the layout along with the working space needed for wiring and installation.
How do WEEE, RoHS and REACh matter when selecting this breaker?
RoHS addresses restrictions on hazardous substances, REACh addresses chemical substance requirements, and WEEE addresses electrical equipment waste handling. These standards are relevant when your project has environmental compliance or end-of-life handling requirements.
