Product FAQs
7 answersWhich Siemens panelboards are compatible with the 3VA6225-5KL31-2AA0?
This breaker is designed for use in Siemens P1, P2, P3, P4, and P5 panelboards, as well as compatible Siemens switchboards.
How does the electronic LI trip unit function on this 250A breaker?
The solid state electronic trip unit provides adjustable Long-Time (L) and Instantaneous (I) protection. This allows electricians to fine-tune the overload and short circuit response curves for precise system coordination.
What type of connection is used for the 3VA6225-5KL31-2AA0?
It features a feed-thru connection and is designed for panel mounting. It includes lug terminals for securing the line and load conductors.
What frame size accessories are compatible with this breaker?
This unit is built on the Siemens 3VA62 frame. When sourcing internal accessories like auxiliary switches or shunt trips, ensure they are rated for the SENTRON 3VA62 frame size.
Why use a solid state electronic trip breaker over a thermal-magnetic option?
Electronic trip units like the one in this 3VA6 model offer higher accuracy, adjustable trip settings, and better repeatability during fault conditions compared to traditional thermal-magnetic breakers. This ensures safer and more reliable circuit protection.
Are the trip settings on this Siemens breaker adjustable?
Yes, the electronic trip unit features adjustable dials on the face of the breaker. This allows installers to modify the continuous current and instantaneous pickup levels to match specific load requirements.
Does the 3VA6225-5KL31-2AA0 replace older Siemens 250A breakers?
The 3VA series is the modern replacement for legacy Siemens Sentron frames. However, physical dimensions and mounting hardware differ from older models, so new panel hardware or a retrofit kit is typically required when upgrading.
