Product FAQs
5 answersWhat does the 2100 suffix indicate on the FH360202100 catalog number?
The -2100 suffix signifies that the breaker includes a factory-installed bell alarm switch. This contact alarm provides remote signaling when the breaker trips due to an overload or short circuit.
Is the Square D FH360202100 a current production model?
The FH360202100 is part of the legacy F-Frame series, which Schneider Electric has superseded with the modern PowerPact H-Frame line. Legacy F-Frame breakers are typically sourced to maintain existing I-Line panels without the need for a complete system upgrade.
How does the FH frame compare to the standard FA frame breakers?
The FH frame is the high-interrupting version of the standard F-Frame series. While a standard FA breaker provides an 18kA interrupting rating at 480VAC, the FH360202100 delivers an upgraded 25kA interrupting rating at 480VAC for systems with higher available fault currents.
How does the FH360202100 install into a panelboard?
This breaker features an I-Line style plug-in connection, allowing it to mount directly onto the bus assembly of Square D I-Line panelboards and switchboards. This plug-on design eliminates the need for bolt-on wire connections at the line side, speeding up installation.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the breaker provides Long-Time and Instantaneous protection. The long-time function protects against sustained overloads, while the instantaneous function provides immediate tripping during severe short circuits.
