Product FAQs
7 answersWhat does the 1021 suffix mean on the FHL360601021 catalog number?
The 1021 suffix indicates that this breaker includes a factory-installed 120-240VAC shunt trip mechanism. This allows the breaker to be tripped remotely by applying voltage to the shunt trip coil.
Can I install the FHL360601021 in a Square D I-Line panelboard?
No, the FHL360601021 is a unit-mount circuit breaker equipped with line and load lugs. It is not compatible with I-Line panelboards, which require a plug-on connection. It is designed for use in standard Square D enclosures, switchboards, and motor control centers.
What wire sizes are accepted by the standard lugs on this breaker?
The factory-installed lugs on the FHL360601021 accept 14 to 1/0 AWG copper wire or 12 to 1/0 AWG aluminum wire. Ensure proper torque specifications are followed during installation as outlined on the breaker faceplate.
Is the trip unit on the FHL360601021 adjustable?
No, this breaker features a thermal-magnetic trip unit with fixed thermal and fixed magnetic settings. If your application requires adjustable trip curves, you will need to look at a different frame or a modern breaker with an electronic trip unit.
What is the modern replacement for the legacy FHL360601021?
The modern equivalent is the Square D PowerPact H-Frame series. However, upgrading to a PowerPact breaker may require different mounting hardware or panel modifications compared to using this exact-fit legacy F-Frame replacement.
What does the LI trip function code mean on this breaker?
LI stands for Long-Time and Instantaneous trip functions. The long-time function protects against sustained overloads, while the instantaneous function provides immediate tripping during severe short circuits to protect the electrical system.
Is the FHL360601021 suitable for 480V systems with high fault current?
This breaker has an interrupting rating of 25kAIC at 480VAC. You must verify that the available fault current at the installation point does not exceed this rating to ensure safe operation.
