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

The various mounting configurations offer
manufacturers a wide range of cost and
space saving solutions and a large
choice of equivalent products to users.
