      • Burst-Firing (Zero Cross Fire) Turns Power ON and OFF During The AC Cycle At Zero Potential. This Type Of Relay Should Be Protected With Semiconductor Fuses. On A High Fault Short These Type Of Fuses Open In Tenths Of a Millisecond .  The Fuse Should Be Sized 125% Of The Current Load Of The Relay.  The I²T Rating Of The Fuse Must Be Below The Maximum I²T Rating Of The Relay.

        NOTE: (I²T) Rated Current Squared Multiplied by Time (Seconds)
