Eaton C350KT61 – Frequently Asked Questions
1) What amperage options does the Eaton Freedom Class J fuse block kit come in?
Two amp ratings are offered: a 30 amp version (MPN C350KT61) and a 60 amp version (MPN C350KJ62). Both are three-pole, 600V, top-mounted kits for Freedom Starters and Contactors. Size the kit to the fuses your motor circuit calls for, not to the contactor frame alone.
2) Will this fuse block kit bolt onto my existing Eaton Freedom starter or contactor?
It's a dedicated accessory for Eaton Freedom Series Starters and Contactors, mounting on top of the device rather than beside it. That top-mount arrangement keeps the fused assembly within roughly the same panel footprint as the starter itself. It is not a general-purpose DIN fuse holder, so it won't adapt to another manufacturer's contactor.
3) Do I have to buy the fuses separately for the Eaton C350K fuse block kit?
Yes. The kit is the three-pole fuse block hardware; you supply three Class J fuses sized for the circuit, matched to the 30A or 60A version you order. Class J is a rejection-style fuse class, so only Class J fuses will seat in these clips.
4) Is a 600V Class J fuse block kit suitable for a 480V three-phase motor starter?
Yes. The kit carries a 600V rating, which covers 208V, 240V and 480V three-phase motor control circuits, and its three poles give fused short-circuit protection on all three phases.
5) Should I use a fuse block kit on the starter or a separate fused disconnect in the panel?
A top-mounted fuse block kit keeps the short-circuit protection integral to the starter, which saves panel space and wiring in combination starter assemblies and OEM motor control builds. A separate fused disconnect is what you want when you also need a local lockable means of disconnect, since this kit provides fusing only, not switching.
6) Can I add fused protection to an existing Freedom contactor already in service?
That's one of the intended uses. The kit is listed for contactor and starter retrofits requiring fused protection and for short-circuit protection upgrades, mounting on top of the existing Freedom device. Confirm the amp rating you need first, since the 30A and 60A kits are separate part numbers.
7) Does a Class J fuse block give better short-circuit protection than a Class H or K block?
Class J fuses are current-limiting and physically smaller than Class H/K fuses of the same amperage, and the rejection dimensions prevent a non-current-limiting fuse being substituted. That matters when a motor control assembly's short-circuit current rating depends on current-limiting protection upstream. This kit accepts Class J only.
