Product Overview
S&C Electric 272000 Fusistor Fuse Unit – Unused NOS
You're looking at an S&C Electric Fusistor fuse unit, catalog number 272000, a medium-voltage E-rated fuse element designed for 15 kV-class distribution protection.
S&C Electric built its reputation supplying utilities with protection devices that behave predictably under fault conditions and disappear into the background the rest of the time. The 272000 Fusistor reflects that lineage—engineered for precise operation at very low E-rated currents where coordination matters most.
Product Condition
Unused, new old stock in the manufacturer’s original packaging. The fuse unit has not been installed or energized and shows no signs of field use.
Product Overview
The S&C Electric Fusistor Unit 272000 is a medium-voltage fuse element intended for transformer and feeder protection in distribution-class electrical systems. It is rated for nominal 14.4 kV service and commonly applied in 15 kV-class switchgear, fuse mountings, and metal-enclosed equipment.
This 1/2E E-rated fuse is used where very low continuous current protection is required, allowing proper coordination with upstream protective devices while limiting damage during fault events.

Frequently Asked Questions
What is a Fusistor fuse?
A Fusistor is S&C Electric’s medium-voltage fuse element design used for distribution protection, combining predictable E-rated performance with compatibility across S&C fuse mountings and switchgear.
What does the 1/2E rating indicate?
1/2E denotes a fractional-ampere E-rated fuse intended for very low continuous current applications, commonly used in transformer and specialized distribution protection.
Is this fuse suitable for low-voltage electrical panels?
No. This is a medium-voltage fuse unit designed exclusively for 15 kV-class systems and properly rated equipment.
Does this listing include a fuse holder or mounting?
No. This listing is for the Fusistor fuse unit only. Compatible S&C fuse holders or switchgear are required.
Who should install or replace this fuse?
Installation and replacement must be performed by qualified personnel trained in medium-voltage electrical systems.
Built to act only when conditions demand it, this Fusistor has spent its life waiting on the shelf. Wherever it’s installed next, it will do its work quietly—and decisively.
