) Guide JFHR, File E56412 (7-30A) Guide JEFV,
File E12112; CSA Certified, Class 1423-01, File 53787.
Features and Benefits
• Time-delay, dual-element T Series Edison base plug fuses
provide small motor overload protection when used with
box cover units.
• Time-delay, dual-element S Series plug fuses provide a
rejection feature (when used alone or with Fustat adapters
to retrofit Edison base holders) to prevent overfusing of
branch circuits.
Typical Applications
• S Series — Residential Load Centers
• T Series — Box Cover Units for small motor overload
protection
• Applications benefiting from fuse rejection (S Series only)

Fustat Fuse Adapters
Specifications
Description:
Adapters for using Type S and SL rejection
fuses in Edison base fuse sockets.
Features and Benefits
• Fustat adapters screw into the “Edison” thread fuse sockets
of standard fuse boxes making it easy to retrofit existing
fuse installations
• Available in various amp ratings to cover a wide range of
rating requirements
Typical Applications
• Plug fuse installations where it is desirable to restrict fuse
amp ratings
