Product FAQs
7 answersWhat panelboards are compatible with the Siemens B29000S01?
This bolt-on breaker is designed specifically for Siemens P1 panelboards. The bolted connection secures directly to the bus bar, providing a reliable contact that resists loosening in high-vibration commercial environments.
Does the B29000S01 include a shunt trip?
Yes, this specific catalog number integrates a 120VAC shunt trip mechanism. This allows the breaker to be tripped remotely, which is essential for emergency power-off systems or automated circuit disconnection.
Is this breaker rated for HVAC equipment?
Yes, the B29000S01 is HACR rated. This means it is certified for use with heating, air conditioning, and refrigeration motor loads, providing the necessary delay to handle motor inrush currents without nuisance tripping.
Can this breaker be installed in a standard residential load center?
No. This is a bolt-on molded case circuit breaker built for commercial panelboards, such as the Siemens P1 series. It will not fit in standard residential plug-on load centers.
What frame type and series does this breaker belong to?
The B29000S01 is part of the Siemens B frame family and falls under the BL series of molded case circuit breakers.
What do the LI trip functions indicate on this breaker?
The LI designation means the thermal magnetic trip unit includes long-time and instantaneous protection. The long-time function protects against sustained overloads, while the instantaneous function immediately clears severe short circuits.
Are there any alternate part numbers for this breaker?
While B29000S01 is the primary Siemens catalog number, it is occasionally cross-referenced by suppliers under the part number 6EVR7.

I ordered breakers from this company. They were fast and prompt on the initial order. I ended up returning part of the order as I did not need those breakers. To say the very least I am not satisfied with the return process. They do not respond to emails and will not return a phone call. I'm still waiting on the partial refund for these items as their restocking fee is ridiculously high. Please make sure you are buying what you need from this company as the return process is painful ,frustrating and costly.
