Overview
The Siemens Q230 is a 30 amp, 120/240 volt, two-pole Type QP thermal-magnetic circuit breaker for compatible Siemens load centers. Its common-trip two-pole construction disconnects both conductors together and provides a 10 kA interrupting rating.
Key Features
-
Protection: Thermal-magnetic operation responds to sustained overloads and short-circuit faults.
-
Common trip: Both poles trip together for a two-pole branch circuit.
-
Installation: Plug-in Type QP construction with box-lug load terminals.
-
Standards: UL 489 and CSA references; HACR rated.
