Product FAQs
4 answersCan I install the B220H in a standard residential load center?
No, this breaker is not compatible with standard plug-on residential load centers. It features a bolt-on connection that is engineered specifically for Siemens P1, P2, and P3 commercial panelboards, requiring it to be bolted directly to the panel bus bars.
Is the Siemens B220H a direct replacement for an ITE B220H?
Yes. Since Siemens acquired the ITE brand, they have continued to manufacture this exact breaker frame. A modern Siemens B220H serves as a direct, fully compatible replacement for older ITE breakers sharing the same catalog number.
What is the difference between a standard B220 and the B220H?
The "H" in the B220H catalog number indicates that it is part of the BLH series, which carries a higher 22kAIC interrupting rating. A standard B220 breaker belongs to the base BL series and only has a 10kAIC rating. This makes the B220H appropriate for commercial distribution systems with higher available fault currents.
How does the "LI" thermal-magnetic trip unit protect the circuit?
The "LI" designation means the breaker provides both Long-Time and Instantaneous overcurrent protection. The internal thermal element responds to prolonged, minor circuit overloads by heating up and tripping the breaker, while the magnetic element reacts immediately to interrupt dangerous, high-current short circuits.
