Product FAQs
6 answersWhich panelboards are compatible with the HB3B100 circuit breaker?
This bolt-on circuit breaker is designed for installation in Siemens P1, P2, and P3 commercial panelboards.
What wire material and gauge can be used with the factory lugs on this breaker?
The factory lugs are rated for both copper and aluminum conductors. They accept 8 to 1 AWG copper wire and 6 to 1/0 AWG aluminum wire.
How does the HB3B100 differ from a standard BQ3B100 breaker?
Both breakers share the same physical BQ frame and bolt-on mounting style for Siemens panelboards. However, the HB3B100 features a higher interrupting capacity of 65kAIC at 240VAC for systems requiring greater fault current protection.
Is the HB3B100 circuit breaker HACR rated?
Yes, this breaker carries an HACR rating, making it suitable for protecting heating, air conditioning, and refrigeration equipment circuits.
What type of trip unit is installed in the HB3B100?
It features a fixed thermal-magnetic trip unit that provides both long-time and instantaneous overcurrent protection. The thermal and magnetic trip points are fixed and cannot be adjusted in the field.
How does this breaker connect to the panelboard bus?
The HB3B100 utilizes a bolt-on connection, providing a secure, vibration-resistant mount to the panelboard bus. This is required for commercial P1, P2, and P3 panelboards.
