Product FAQs
5 answersWhat is the difference between the Siemens B290 and B290H circuit breakers?
The primary difference is the interrupting rating. The standard B290 is rated for 10kAIC, while the B290H is the high-interrupting version rated for 22kAIC at 120/240VAC.
Which panelboards are compatible with the B290H breaker?
This bolt-on breaker is designed for installation in Siemens P1, P2, P3, P4, and P5 series commercial panelboards.
Can I install the B290H in a standard Siemens residential load center?
No. The B290H features a bolt-on connection designed specifically for commercial panelboards. Standard Siemens residential load centers require plug-on breakers, such as the QP or QPH series.
Is the Siemens B290H HACR rated?
Yes, this breaker is HACR rated, making it suitable for protecting heating, air conditioning, and refrigeration equipment circuits.
Can the B290H be reverse fed?
Yes. Siemens BLH series breakers are not marked with line and load designations, making them suitable for reverse feed applications in accordance with UL 489 standards.
