Is the Square D FH361001021 still actively manufactured?
No, the Square D F-frame series is a legacy product line and is no longer actively manufactured. For new installations, the Square D PowerPact H-frame series serves as the modern replacement.
What type of panelboard is the FH361001021 designed for?
This breaker features an I-Line style plug-in connection, making it compatible exclusively with Square D I-Line panelboards and switchboards. It cannot be used in standard QO, NQ, or NF load centers.
Can I adjust the trip settings on the FH361001021?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time (overload) and instantaneous (short-circuit) trip functions are factory-set and non-interchangeable.
Does the FH361001021 provide a visual indication when it trips?
Yes, it features a Visi-Trip indicator. When the breaker trips due to an overcurrent or a remote shunt trip activation, the handle moves to a central position and a red indicator becomes visible.
