The primary difference is the interrupting rating. The standard BQ3B030 has a 10kAIC rating at 240VAC, while the BQ3B030H is a high-interrupting variant rated for 22kAIC at 240VAC.
Is the Siemens BQ3B030H HACR rated?
Yes, Siemens BQ series molded case circuit breakers, including the BQ3B030H, are HACR rated for use with heating, air conditioning, and refrigeration equipment.
Can I install the BQ3B030H in a standard residential load center?
No, the BQ3B030H is a bolt-on circuit breaker designed for commercial panelboards. Standard residential load centers typically require plug-on breakers, such as the Siemens QP or QPH series.
Is the BQ3B030H backwards compatible with older ITE panelboards?
Yes, Siemens acquired ITE, and the BQ3B030H is backwards compatible with many legacy ITE bolt-on panelboards that require BQ-frame breakers.
What does the LI trip function mean on the BQ3B030H?
The LI designation indicates that the breaker features Long-Time and Instantaneous trip functions. The thermal Long-Time function protects against sustained overloads, while the magnetic Instantaneous function trips immediately during a short circuit.
