MEDIUM VOLTAGE CAPACITOR FUSES/A100C-A550C
MEDIUM VOLTAGE CAPACITOR FUSES
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 protect against capacitor case rupture
or dielectric failure within the capacitor.
The various mounting configurations offer manu-
facturers a wide range of cost and space saving
solutions and a large choice of equivalent products
to users.
