■
Low I2t minimizes damage to protected components on
short circuit.
Controlled arc voltage reduces stress to circuit components during fuse clearing.
Choice of mounting types provides options for unique
termination requirements.
Indicator options allow identification of blown fuses.
Superior DC capabilities.
APPLICATIONS
Protection of 300 volt heavy duty rectifiers and similar
heavy duty power supplies.
