Product FAQs
4 answersWhat are the adjustable trip ranges for the 3VA6340-5JP31-0AA0?
Equipped with the ETU550 LSI electronic trip unit, this 400A breaker allows precise adjustments via its LCD screen. The long-time overload protection (Ir) is adjustable from 160A to 400A. The short-time delayed short-circuit protection (Isd) ranges from 240A to 4000A, and the instantaneous short-circuit protection (Ii) can be set from 600A to 4000A.
How are the LSI trip parameters configured on this breaker?
Unlike trip units that rely solely on manual rotary dials, the ETU550 trip unit on this breaker features an integrated LCD screen. This allows panel builders and electricians to program and verify the long-time, short-time, and instantaneous settings with high precision.
Does the 3VA6340-5JP31-0AA0 provide ground fault protection for equipment?
No, this breaker is equipped with an LSI trip unit (Long-Time, Short-Time, Instantaneous) and does not include an integrated ground fault (G) function. If your application requires equipment ground fault protection, you will need a variant with an LSIG trip unit, such as the ETU556.
What does the M-Class designation mean for this 3VA6 circuit breaker?
The M-Class rating indicates a medium breaking capacity. For this 400A frame, it delivers a maximum interrupting rating of 35kA at 480VAC and 100kA at 240VAC, making it suitable for standard commercial and industrial distribution systems.
