New 40 amp time delay fuse ace 31074, frn-r-40 ** **
This listing is for one (1) 40 amp heavy duty time-delay cartridge fuse by ACE. Time delay fuses are used on circuits where appliance motors have initial surges of electrical power when the motor starts. This initial surge might blow a regular fuse. These type of fuses help protect motors from burnout caused by overloads or single phasing. The time delay feature allows the initial startup surge for typical motors to pass, but opens prior to burnout when longer dangerous overloads are present.
