Built for heavy-duty industrial applications, this 100A Sentron series breaker delivers consistent thermal-magnetic trip performance. The 3-pole device ensures safe electrical distribution across 480VAC and 600Y/347VAC commercial networks. The bolt-on configuration mounts into Siemens P3, P4, and P5 panelboards. Facilities planning future upgrades should note this frame is replaced by the HEG3B100B.
