Panel Compatibility

The Square D QBL32100 is a bolt-on, 3-pole, 100A, 250V molded-case circuit breaker from the QBL frame series. As a bolt-on MCCB, it is designed for installation in compatible Square D panelboards and switchboards that accept QBL-frame bolt-on breakers — typically commercial and light industrial applications rather than residential plug-on loadcentres. It is not a plug-in breaker and will not fit QO or Homeline residential loadcentres.
