Description
Characterized by its 4-pole width footprint, the Siemens MBK175 is a 175-amp main breaker kit built for residential applications. It delivers essential thermal-magnetic protection for primary electrical service entrances. This plug-on unit is specifically designed to install into Siemens EQ Series load centers.
