Product FAQs
6 answersWhat panelboards are compatible with the HF3B090 circuit breaker?
This bolt-on breaker is designed for use in Siemens Sentron panelboards, as well as P1, P2, and P3 panelboards, switchboards, and motor control centers.
What does the H in the HF3B090 catalog number signify?
The H indicates a high interrupting capacity rating. This F-frame model provides up to 65kA interrupting capacity at 480VAC and 240VAC, which is higher than standard-rated versions.
Can the Siemens HF3B090 replace older ITE circuit breakers?
Yes, Siemens acquired ITE, and the HF3B090 is a direct replacement for legacy ITE Sentron F-frame breakers with the exact same catalog number.
Does the HF3B090 include line and load side lugs?
Because it is a bolt-on breaker, the line side mounts directly to the panel bus without lugs. It comes complete with load side lug terminals that accept 10 to 1/0 AWG copper or aluminum wire.
How does the trip unit on the HF3B090 operate?
It uses a thermal magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection.
Can this breaker be used in DC applications?
Yes, the HF3B090 is rated for up to 250VDC with a 10kA interrupting capacity, making it suitable for specific direct current systems.
