Time-delay characteristics handle motor in-rush currents without nuisance trips. Its current-limiting ability and wide range of ratings provide excellent overcurrent protection for all your applications. An optional mechanical blown fuse indicator and Microswitch is available on blade-type (70 to 600A) fuses for visual and/or remote blown fuse indication. 600 Volts 600 amps with offset EI indicator for microswitch mounting.
