B-LINE 70-7758-27 – Frequently Asked Questions
1) What safety switch does the B-Line 70-7758-27 fuse base fit?
Model 70-7758-27 is a replacement fuse base for 30A, three-pole, 600V fusible safety switches. If your disconnect is rated at a different amperage or voltage class, this base is not the right part.
2) Is this fuse base rated 600 volts and 30 amps?
Yes. The 70-7758-27 base carries a 30A amperage rating and a 600V voltage rating, matching the fusible switch it goes into.
3) Can this fuse base be used in a six-pole switch as well as a three-pole?
The base is listed for three-pole and six-pole configurations, but the switch application it is called out for is 30A, three-pole, 600V fusible safety switches. On a six-pole assembly the bases are used in multiples, so count what your enclosure needs before ordering.
4) Is this a heavy duty or general duty disconnect part?
Heavy duty. The 70-7758-27 fuse base is classified as a heavy duty switch component, so it belongs in HD-series 600V fusible disconnects rather than general duty 240V residential-style switches.
5) Do fuses come with the B-Line 70-7758-27 fuse base?
No. This is the fuse base only, the mounting and clip assembly inside the switch. Class R or Class J fuses sized for your 30A 600V circuit are ordered separately, as is any rejection kit your switch calls for.
6) Is 70-7758-27 the actual Eaton part number to order?
Yes. 70-7758-27 is the manufacturer part number for this B-Line Eaton fuse base, and it is the number to quote for a 30A 600V heavy duty fusible switch replacement.
7) How heavy is the 70-7758-27 fuse base, and is there a spec sheet?
It is listed at 1 lb, a single small component rather than a full switch interior. Eaton publishes a spec sheet for 70-7758-27 that is linked on the product record if you need to match it against your disconnect drawing.
