Product FAQs

5 answers
Which electrical panels are compatible with the Siemens Q230 breaker?

The Q230 is a Type QP breaker engineered for Siemens PL and ES series load centers. Because Siemens acquired ITE and Murray, this breaker also serves as the direct plug-on replacement for legacy ITE, Gould, and Murray panels that accept QP style breakers. It is not compatible with GE, Square D, or Eaton panelboards.

Is the Siemens Q230 circuit breaker HACR rated?

Yes, the Q230 is HACR rated. This means it is independently tested and approved to provide reliable circuit protection for heating, air conditioning, and refrigeration equipment.

How many spaces does this breaker take up in a load center?

As a standard full-size 2-pole miniature circuit breaker, the Q230 requires two standard 1-inch spaces on the panel bus bar.

Does the Siemens Q230 include the Insta-Wire feature?

Yes, this breaker features the Siemens Insta-Wire design. The lug terminal screws are backed out and ready for wire insertion straight from the factory, which speeds up the wiring process for panel builders and installers.

How does the thermal-magnetic trip mechanism operate on this breaker?

The thermal element provides long-time overload protection by tripping when it detects gradual heat buildup from excess current over time. The magnetic element provides instantaneous short-circuit protection, tripping the breaker immediately when a severe fault current is detected.
