Description
Part of the B-Series lineup, the Siemens B1515NI provides space-saving circuit density by packing two 15A circuits into a single-pole bolt-on footprint. Built for commercial and industrial applications, this non-interchangeable trip breaker delivers reliable thermal-magnetic protection. It mounts securely into compatible Siemens panelboards and serves as a drop-in replacement for older BL Series 1-pole breakers in retrofit scenarios. Rated for 10kAIC at 120/240VAC and HACR applications.Specifications

Product FAQs
7 answersWhat panels are compatible with the Siemens B1515NI?
This tandem breaker is designed for use in compatible Siemens load centers. Always verify your specific panelboard is rated to accept tandem breakers before installation.
What wire sizes do the terminals on the B1515NI accept?
The breaker lugs accommodate 14 to 10 AWG copper wire or 12 to 10 AWG aluminum wire.
What does the "NI" in the B1515NI catalog number stand for?
The "NI" indicates a non-interchangeable trip unit, meaning the thermal-magnetic trip mechanism is fixed and cannot be swapped or adjusted.
How does a tandem breaker like the B1515NI save panel space?
A tandem breaker packs two independent 15-amp circuits into a single-pole footprint, allowing you to add a new branch circuit without requiring an additional slot in the load center.
What type of protection does the Siemens B1515NI provide?
It features thermal-magnetic trip technology with fixed long-time and instantaneous trip functions to protect your electrical system against overloads and short circuits.
Are the two circuits on the B1515NI common-trip or independent?
Tandem breakers like the B1515NI feature independent trip mechanisms. If one of the 15-amp circuits experiences an overload or short circuit, it will trip without affecting the other circuit.
Is the Siemens B1515NI suitable for HVAC equipment?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires this specific classification.

I ordered breakers from this company. They were fast and prompt on the initial order. I ended up returning part of the order as I did not need those breakers. To say the very least I am not satisfied with the return process. They do not respond to emails and will not return a phone call. I'm still waiting on the partial refund for these items as their restocking fee is ridiculously high. Please make sure you are buying what you need from this company as the return process is painful ,frustrating and costly.
