Product FAQs

6 answers
Which panelboards are compatible with the Siemens B2110?

This bolt-on breaker is designed specifically for installation in Siemens P1, P2, P3, P4, and P5 commercial panelboards.

What frame type is the Siemens B2110?

The B2110 is a Type BL (B-frame) molded case circuit breaker. It requires a bolt-on connection and is not compatible with residential load centers that use plug-on designs.

What wire sizes are accepted by the B2110 terminals?

The included load-side lugs accommodate 2 AWG to 1/0 AWG copper (Cu) conductors, or 1/0 AWG to 2/0 AWG aluminum (Al) conductors.

Is the Siemens B2110 suitable for HVAC applications?

Yes, this breaker is HACR rated, meaning it is safety approved for use with heating, air conditioning, and refrigeration motor loads.

How does the trip unit operate on this breaker?

It utilizes a fixed thermal-magnetic trip unit. The thermal component provides long-time protection against sustained overloads, while the magnetic component offers instantaneous protection against short circuits.

What is the interrupting capacity of the B2110?

This breaker has a standard interrupting rating of 10kAIC at 120/240VAC. Applications requiring higher fault current ratings will need the Type BLH (22kAIC) or Type HBL (65kAIC) series equivalents.
