9 answersWhich panelboards and switchboards can the 3VA5222-5EC31-0AA0 be installed in?
This feed-thru circuit breaker is compatible with Siemens P1, P2, and P3 panelboards, as well as SB switchboards and motor control centers. Appropriate mounting strap kits or connecting hardware are required depending on the specific enclosure type.
Can the Siemens 3VA5222-5EC31-0AA0 be used in direct current (DC) systems?
Yes, this 3-pole breaker is suitable for DC applications. It carries a maximum 500VDC voltage rating and provides a 50kA fault current interrupting capacity for DC networks.
How is the TM230 trip unit adjusted on this breaker?
The TM230 trip unit features fixed thermal overload protection set at the 225A continuous current rating. The magnetic short-circuit protection is field adjustable and can be set between 5 and 10 times the rated current (1,125A to 2,250A).
What breaking capacity class does the '5' in the 3VA5222-5EC31 catalog number indicate?
The '5' designates Siemens' Class M breaking capacity. This provides a medium-tier interrupting rating of 35kA at 480VAC and 18kA at 600VAC.
What does the 3VA52 frame designation mean?
It indicates this is a 3VA5 series, UL frame size 250 breaker. While the physical frame has a maximum capacity of 250 amps, this specific model is factory-equipped with a 225A continuous current rating.
Can the Siemens 3VA5222-5EC31-0AA0 be reverse fed?
Yes, Siemens 3VA5 thermal-magnetic circuit breakers are UL listed for reverse feed applications, allowing power to be supplied to either the top or bottom terminals.
Is this 225A Siemens breaker HACR rated?
Yes, this molded case circuit breaker carries an HACR rating, making it UL approved for use with commercial heating, air conditioning, and refrigeration equipment.
Can auxiliary switches or shunt trips be added to this breaker?
Yes, the 3VA5 molded case circuit breaker design includes internal accessory pockets. This allows for the field installation of modular auxiliary switches, alarm switches, undervoltage releases, and shunt trips.
Does this specific 225A breaker provide equipment ground fault or arc fault protection?
No, the 3VA5222-5EC31-0AA0 provides standard thermal-magnetic line protection against overloads and short circuits. It does not include built-in ground fault (GFCI or GFEP) or arc fault (AFCI) protection.
