Product FAQs
7 answers
How should I use the 225A rating when selecting this breaker?
The Siemens 3VA5222-6EC61-0AA0 has a rated current of 225A. Use that rating when coordinating breaker selection with the circuit load and conductor protection requirements.
Can this breaker be selected for AC or DC circuits?
The voltage ratings are 600VAC and 250VDC. Use the rating for the circuit's current type, and select it for a circuit voltage that does not exceed that rating.
How does the 65kAIC rating affect selection for a 480V circuit?
At 480V, the interrupting rating is 65kAIC. Compare this rating with the available fault current at the installation point; the available fault current must not exceed the interrupting rating.
What protection does the trip unit provide, and which setting can I adjust?
The thermal-magnetic trip provides long-time protection for sustained overloads and instantaneous protection for short-circuit currents. The thermal setting is fixed, while the magnetic setting is adjustable so the instantaneous pickup can be selected for the application.
What circuit configuration should I select this breaker for?
This is a 2-pole breaker for single-phase circuits. Choose it when the circuit design requires two poles of protection in a single-phase application.
What does fixed mounting mean for installation?
Fixed mounting means the breaker is secured in a stationary installation rather than used as a drawout device. Plan installation and service access around that mounting arrangement.
What dimensions should I use when planning installation space?
The breaker is 7.3 in high, 4.1 in wide and 4.2 in deep. Use these dimensions to plan its physical space, with wiring space and working clearances considered separately.
