(1) Total current through center (ground) electrode, both line electrodes pulsed simultaneously; half value through
each respective line terminal.
(2) 100 amps, 10/1000µS pulse (does not apply to SL1021A200)
(3) 10 shots, A.C. 60Hz, 1 sec duration.
(4) 10 shots, 8/20µS waveform
(5) either end (line) electrode to centre (ground) electrode
(6) Meets the requirements of BT Type 21A.
(7) Meets the requirements of BT Type 14A. Addition of ‘F’ (failsafe) option meets the requirements of BT type
number 14A/1.
