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.
