Product FAQs
8 answers
What are the adjustable trip ranges for the 3VA6225-5HN31-0AA0 circuit breaker?
The ETU350 LSI trip unit features an adjustable long-time pickup (Ir) from 100A to 250A. The short-time pickup (Isd) is adjustable from 1.5x to 10x the Ir setting, with a short-time delay (tsd) of 0 to 0.4 seconds. The instantaneous pickup (Ii) is fixed at 10x the nominal rating, or 2500A.
What breaking capacity class does the 5 in the catalog number indicate?
The 5 located after the amperage (3VA6225-5) designates it as a Class M (Medium breaking capacity) breaker. For the 3VA6 series, Class M yields an interrupting rating of 35 kA at 480 VAC and 18 kA at 600 VAC.
Is the 3VA6225-5HN31-0AA0 rated for 100 percent continuous current?
No, the 0AA0 suffix indicates it is a standard 80 percent rated breaker. For a 100 percent rated equivalent, you would need the catalog number 3VA6225-5HN31-2AA0.
Does the 3VA6225-5HN31-0AA0 ship with terminal lugs included?
No. The 1 in the 8th position of the catalog number (HN31) indicates this breaker ships without terminal connections. Standard lugs must be sourced separately.
Which standard Siemens lug kit supports up to 350 kcmil wire on the 3VA62 frame?
Use Siemens part number 3VA9243-0JB12. This is a 3-piece aluminum body lug kit rated for single-wire copper or aluminum conductors ranging from 6 AWG to 350 kcmil.
What tool is required to initiate test trips on the ETU350 trip unit?
The Siemens TD500 test device (catalog number 3VA9977-0MB10) is required. It connects directly to the front interface of the ETU350 to activate test trips and provides a USB interface for PC parameterization using Siemens powerconfig software.
Which auxiliary switch types fit the internal accessory compartment of this breaker?
The 3VA62 frame accepts both Type HQ (compact 7 mm) and Type HP (14 mm) internal auxiliary switches. A common choice is the Type HQ switch (part number 3VA9978-0AA12), which snaps directly into the breaker without requiring tools.
Does the ETU350 LSI trip unit provide thermal memory protection?
Yes, the ETU350 LSI features a permanently active thermal image. This protects equipment by tracking the thermal history of recent overcurrent events, ensuring the breaker trips faster if successive overloads occur before the conductors have cooled.
