Product FAQs
5 answersWhich panelboards are compatible with the HFD62B125 circuit breaker?
This breaker is designed for use in Siemens Sentron P1, P2, and P3 panelboards, as well as compatible switchboards and motor control centers.
How does the trip unit function on the HFD62B125?
It features a thermal magnetic trip unit with a fixed thermal setting for overload protection and an adjustable magnetic setting for short-circuit protection. This allows you to customize the magnetic trip point based on specific system requirements.
What is the standard lug catalog number for the HFD62B125?
The standard aluminum body lug for this FD frame breaker is the TA1FD350A. It accommodates a single conductor per phase, accepting 6 AWG to 350 kcmil copper wire or 4 AWG to 350 kcmil aluminum wire.
What is the difference between the FD62B125 and the HFD62B125?
The HFD62B125 is the high interrupting capacity version of the standard FD frame breaker. It provides a 65kAIC rating at 480VAC, whereas the standard FD62B125 has a 35kAIC rating at 480VAC.
What does the B in the HFD62B125 catalog number indicate?
The B indicates that the circuit breaker includes line and load lugs. A catalog number with an F instead of a B indicates a frame-only unit that ships without lugs.
