Product FAQs
7 answersWhat panelboards are compatible with the Siemens 3VA5212-7EC31-0AA0?
This 3-pole circuit breaker is designed for use with Siemens P2, P3, P4, and P5 panelboards, as well as compatible Siemens switchboards.
What frame size is the 3VA5212-7EC31-0AA0?
It belongs to the Siemens 3VA52 frame size, which is a 250A maximum frame, even though this specific breaker is rated for 125 amps. This is useful for sizing enclosures and selecting frame-specific accessories.
What type of trip unit is equipped on the 3VA5212-7EC31-0AA0?
It features a TM230 thermal-magnetic trip unit with fixed thermal (long-time) and adjustable magnetic (instantaneous) protection functions. The adjustable magnetic trip allows electricians to fine-tune the instantaneous short-circuit response to suit specific load requirements, while the thermal overload protection remains fixed at 125 amps.
What does the Class C breaking capacity mean for this breaker?
In the Siemens 3VA series, a Class C breaking capacity indicates a very high interrupting rating. For this specific breaker, it provides a 100kA interrupting capacity at 480VAC.
How is the 3VA5212-7EC31-0AA0 mounted?
This breaker features a feed-thru connection and is configured for DIN rail mounting, making it suitable for standardized control panels and enclosures.
Can I use this breaker in DC applications?
Yes, this breaker is rated for DC applications up to 750VDC. When applying three-pole breakers on ungrounded DC systems, it is important to connect the power supply in a series or zig-zag configuration across the poles to ensure voltage is uniformly distributed.
Is the 3VA5212-7EC31-0AA0 suitable for reverse feeding?
Yes, all Siemens 3VA5 thermal-magnetic trip circuit breakers, including this model, are UL listed for reverse feed applications.
