Ferraz Shawmut E-rated PT fuses are current limiting fuses with high interrupting rating, used for primary winding protection of potential transformers. They are small dimension, ferrule-type fuses and mounted in standard clips. Ratings are 1/2E to 5E at 2.4, 4.8, and 5.0kV. At 7.2kV ratings are 1/2E to 3E.  At 15.5 kV ratings are 1/2E to 3E. …more

Non-Load disconnects and supports for 2.4kV up to 38kV.  These are availble in both indoor and outdoor instalations. A wide variety of clips and live parts for both supports and disconnects are also available …more

Ferraz Shawmut capacitor fuses are designed to ANSI C37-41. They are current limiting operating without noise or discharge and are designed to be used indoors in a general purpose enclosure or outdoors in a weatherproof enclosure. These are non-disconnecting fuses requiring the use of a disconnect switch. These capacitor fuses provide both short circuit and overload protection and are intended to …more

The Sure Guard ETP back-up current-limiting fuses are designed to protect distribution transformers and are used in series with another protective device (such as an expulsion fuse). …more
