Product FAQs
7 answersWhat legacy Siemens circuit breaker does the 3VA5325-7EC31-0AA0 replace?
This breaker serves as a modern replacement for the legacy Siemens CJD63B250 molded case circuit breaker, offering an upgraded design while maintaining a 250A rating and 100kAIC at 480V.
What type of trip unit is installed in the 3VA5325-7EC31-0AA0?
It features a TM230 thermal-magnetic trip unit with fixed thermal protection (Ir=250A) and an adjustable magnetic short-circuit response (Ii=5 to 10 times the continuous current).
Which Siemens panelboards are compatible with this 3VA5 breaker?
This breaker is designed for use in Siemens 3VA panelboards and switchboards, including compatible P-Series distribution panels such as the P2, P3, P4, and P5 models.
What is the breaking capacity class for this circuit breaker?
The 3VA5325-7EC31-0AA0 is a Class C breaking capacity breaker, which provides a high interrupting rating of 100kA at 480V and 200kA at 240V.
Can the 3VA5325-7EC31-0AA0 be used in DC voltage applications?
Yes, this breaker is rated for use in DC systems up to 500VDC, providing a 100kA interrupting capacity. For 500V ungrounded DC systems, the power supply must be connected in a series or zig-zag configuration across the poles to ensure voltage is uniformly distributed.
What is the frame size of the 3VA5325-7EC31-0AA0?
Although it has a continuous current rating of 250A, this specific breaker is built on the larger Siemens 3VA5 UL 400A frame size.
Is this breaker suitable for reverse feed applications?
Yes, Siemens 3VA5 thermal-magnetic circuit breakers are UL listed for reverse feed applications.
