Siemens 3VA5222-5ED31-0AA0 Molded Case Circuit Breaker

This 3VA5 breaker serves as a modern replacement for the legacy Siemens FXD63B225 molded case circuit breaker. When retrofitting this unit into an older existing panelboard, an appropriate P1 mounting kit is typically required.

The TM210 designation identifies the specific thermal-magnetic trip unit installed in the breaker. It signifies an FTFM configuration, meaning both the thermal (overload) and magnetic (short-circuit) trip points are fixed and cannot be field-adjusted.

This unit is built on the Siemens 3VA52 frame architecture. While this specific breaker is calibrated for a 225A continuous current, the 3VA52 frame encompasses models rated up to a 250A maximum, ensuring standardized mounting dimensions and accessory compatibility across the frame class.

Yes, the Siemens 3VA series features a modular design that supports various field-installable internal accessories. Add-ons such as auxiliary switches, alarm switches, shunt trips, and undervoltage releases can be installed directly into the breaker's accessory pockets.

No. The standard LI (Long-Time and Instantaneous) trip function on this specific model is designed for standard overloads and short circuits only. It does not include built-in ground-fault monitoring or equipment protection.

This molded case circuit breaker is engineered to operate reliably in ambient temperatures ranging from -25 degrees Celsius to 70 degrees Celsius (-13 degrees Fahrenheit to 158 degrees Fahrenheit), making it suitable for demanding industrial and commercial environments.

No, this specific model features fixed thermal and fixed magnetic trip points. If your application requires precise coordination or adjustable pickup settings, you will need to select a breaker equipped with an adjustable electronic trip unit or an adjustable thermal-magnetic unit.

Yes, the mechanical thermal-magnetic trip mechanism allows this breaker to be utilized in DC applications. It carries a DC rating of up to 500V DC and delivers an interrupting capacity of 50kA in direct current circuits.
