Product FAQs
7 answersWhat types of enclosures or panels is this breaker compatible with?
This breaker mounts into Siemens P4 and P5 panelboards, switchboards, and motor control centers.
What does the LSIG designation mean on the ETU560 trip unit?
LSIG stands for Long-Time, Short-Time, Instantaneous, and Ground-Fault. The ETU560 electronic trip unit allows you to adjust these four parameters for precise coordination and equipment protection.
Does the ETU560 trip unit include a display?
Yes, the ETU560 features an integrated LCD screen that allows you to easily view and configure the trip settings directly on the breaker.
Can this breaker replace older Siemens 400A breakers?
Yes, the 3VA63 frame serves as a modern replacement for legacy 400A JD-frame, such as the JD63B400, and VL JG-frame circuit breakers.
What does the 5 in the 3VA6340-5JQ31-0AA0 part number indicate?
The 5 indicates a Class M medium breaking capacity. This corresponds to the 35kA interrupting rating at 480V.
Does this breaker come with terminal lugs?
No, this specific catalog number is supplied with a feed-thru connection using punched copper bars and does not include terminal lugs. Lugs must be sourced separately for your specific wire size.
How does the ground-fault function improve system safety?
The ground-fault protection setting detects low-level leakage currents to ground, tripping the breaker to prevent equipment damage and reduce fire risks before a major short circuit occurs.
