Product FAQs
7 answersWhich panelboards are compatible with the Siemens B2100HH circuit breaker?
The B2100HH is a bolt-on circuit breaker designed specifically for installation in Siemens P1, P2, P3, P4, and P5 panelboards.
What wire sizes are accepted by the lugs on the B2100HH breaker?
The included terminal lugs accept 4 to 1/0 AWG copper wire or 2 to 2/0 AWG aluminum wire. Ensure proper torque specifications are followed during installation.
Is the Siemens B2100HH suitable for use with HVAC equipment?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration motor loads.
What does the 65kAIC rating on the B2100HH indicate?
The 65kAIC rating means this breaker can safely interrupt up to 65,000 amps of fault current at 120/240VAC. This extra-high interrupting capacity is required for commercial or industrial systems with high available fault currents.
How does the B2100HH mount into the panelboard?
This is a bolt-on circuit breaker. It secures directly to the panelboard busbars using screws, providing a highly secure connection that resists loosening in environments with mechanical vibration.
What frame type is the Siemens B2100HH?
The B2100HH belongs to the Siemens B-frame family and is classified as a Type HBL breaker. The HBL designation indicates its extra-high 65kAIC interrupting rating compared to standard BL types.
How does the thermal-magnetic trip unit in the B2100HH operate?
It utilizes a fixed thermal element for long-time (L) protection against sustained overloads and a fixed magnetic element for instantaneous (I) protection against sudden short circuits.
