Product FAQs
5 answersCan I install the B2100H in a standard residential load center?
No, the B2100H features a bolt-on connection designed specifically for Siemens commercial panelboards, including the P1, P2, P3, P4, and P5 series. Standard residential load centers typically require plug-on breakers.
What is the difference between the Siemens B2100 and the B2100H?
The standard B2100 (Type BL) has an interrupting rating of 10kAIC, while the B2100H (Type BLH) is a high-interrupting breaker rated for 22kAIC at 120/240VAC. Both share the same physical footprint and bolt-on mounting style.
What wire gauge and material should be used with the B2100H terminals?
The terminal lugs on this breaker accept 4 to 1/0 AWG copper (Cu) conductors or 2 to 1/0 AWG aluminum (Al) conductors. Always verify that your selected wire size meets National Electrical Code (NEC) requirements for a 100A circuit.
Is the Siemens B2100H backwards compatible with older ITE panelboards?
Yes. Siemens manufactures the BLH frame as a direct replacement for legacy ITE and Gould Type BLH bolt-on circuit breakers. It will fit into the same commercial panelboard spaces that originally housed the older ITE versions.
What type of trip mechanism does the B2100H use?
It utilizes a fixed thermal-magnetic trip unit with Long-Time and Instantaneous (LI) functions. The thermal component provides delayed protection against sustained overloads, while the magnetic component trips immediately during a short circuit.
