Product FAQs
8 answersWhat frame size does the 3VA5217-6EF31-0AA0 belong to?
This 175A breaker is part of the Siemens 3VA52 frame family, which has a maximum physical frame capacity of 250A.
Are internal accessories field-installable on the 3VA5217-6EF31-0AA0?
Yes, the 3VA5 series features internal accessory pockets that allow for field installation of components like shunt trips, auxiliary switches, and undervoltage releases. These accessories are color-coded and designed to fit into specific slots under the front cover.
Can this circuit breaker be used in reverse feed applications?
Yes, Siemens 3VA5 thermal-magnetic molded case circuit breakers are UL listed for reverse feed applications.
What does the LI trip function code indicate for this breaker?
The LI designation means the trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection. Both the thermal and magnetic trip thresholds are adjustable on this specific model.
How do you adjust the thermal and magnetic trip settings?
The trip settings are adjusted using the rotary dials located on the front face of the thermal-magnetic trip unit. This allows you to fine-tune the overload and short-circuit response to match your specific load requirements.
Is the 3VA5217-6EF31-0AA0 suitable for DC voltage systems?
Yes, this breaker is rated for DC applications up to 750V DC, with an interrupting capacity of 85kA at 750V DC. When applying it on 500V or 750V ungrounded DC systems, specific series wiring configurations across the poles are required per Siemens guidelines.
Does this breaker provide ground fault protection?
No, this unit features a standard LI (Long-Time and Instantaneous) thermal-magnetic trip unit. It does not include integrated ground fault protection.
What type of panels will accept this breaker?
It is designed for installation in Siemens 3VA panelboards, switchboards, and compatible enclosures. In specific Siemens panels like the P3, 3VA52 breakers can be mounted in a compact nose-to-nose configuration to save unit space.
