hey whats up everyone. Does anyone know where I would found the time current curves for a federal pacific draw out breaker? I tried their website, and you think the company never even made breakers. The model type is a FPS 25, and the serial number is XSF-276027-2. Any help would be greatly appreciated. Thanks.

What type of trip unit? Not sure about FPS, but I have some time bands for FP25, FP30, FP50, FP75 with TD1, TD2, and SS1 - SS6 trip units.
