Product FAQs
5 answersWhat equipment is the Federal Pacific XJL434175 designed to fit?
This 175A XJL frame breaker is a direct bolt-on replacement for legacy Federal Pacific switchgear and panelboards. It installs directly into the original enclosures without requiring aftermarket adapters.
How does the XJL434175 achieve its high interrupting capacity?
As part of the Federal Pacific Fusematic series, this current-limiting breaker pairs a standard thermal-magnetic trip unit with internal fuses. This hybrid design allows it to safely clear severe faults, delivering up to a 150kAIC rating at 480VAC.
What is the required mounting method for this circuit breaker?
The XJL434175 utilizes a bolt-on connection. During installation, the breaker terminals must be securely bolted directly to the panelboard or switchgear busbars to ensure a reliable, high-amperage connection.
How does the thermal-magnetic trip unit operate on the XJL434175?
The breaker features fixed long-time and instantaneous (LI) trip functions. The thermal element provides long-time protection against sustained overloads, while the magnetic element offers instantaneous tripping to quickly isolate short circuits.
Can the XJL434175 replace other Federal Pacific XJL frame breakers?
Yes, it shares the standard XJL frame dimensions and can replace older 175A, 3-pole variants in Federal Pacific gear. Always verify that its 150kAIC at 480V or 100kAIC at 600V meets or exceeds the available fault current of your specific system.
