Product FAQs

6 answers
Which Siemens panelboards accept the QA120AFCHH breaker?

It is compatible with Siemens EQ, PL, ES, and Ultimate load centers. It requires a standard 1-inch space and a neutral bar connection for the pigtail.

How is the neutral connected on the QA120AFCHH?

This model uses a pigtail neutral wire that must be routed and terminated directly to the neutral bus bar in the panel. It is not a plug-on neutral breaker.

What does the HH suffix indicate on this Siemens AFCI breaker?

The HH designates a high interrupting capacity of 65kAIC at 120VAC, making it suitable for electrical systems with high available fault current.

What type of arc fault protection does this combination AFCI provide?

As a combination AFCI, it detects and mitigates both parallel arcing faults, such as line-to-neutral or line-to-ground, and series arcing faults, like a broken wire or loose connection.

Does this breaker include diagnostic indicators for troubleshooting?

Yes, it features an LED trip indicator to help electricians quickly identify the cause of a fault after the breaker trips.

Does this breaker feature Insta-Wire connectors?

Yes, it includes Insta-Wire connectors. The terminal screws are shipped backed out and ready for immediate wire insertion to speed up installation.
