Siemens P1A30HB100CTST Circuit Breaker

Siemens P1A30HB100CTST is a single‑phase circuit breaker designed for panelboards with 120/240 V service. It belongs to Siemens’ P1 protection family and provides overcurrent protection for branch circuits within a compatible panelboard. The exact electrical specifications—current rating, interrupting capacity, and trip characteristics—are defined by the model code and should be verified in the official Siemens datasheet or listing for this part. Typical applications include protecting lighting, receptacle, and small‑appliance circuits in residential or light commercial installations where 120/240 V single‑phase power is distributed.
