*Substitute “-1B” or “-1C” in place of “-1A” for 1 Form B or 1 Form C respectively. For silver tin oxide contacts substitute “-1AE”, or "1BE" or “-1CE” in place of “-1A”
or “-
1B", or "1C". For 30A version - add “H” after "-1A","-1AE","-1B","-1BE","-1C","-1CE" or for 50A version - add "T" after “-1AE”, “-1BE”, or “-1CE.” To
indicate class F version - add suffix “F”. Substitute “DE” or “AE” in place of “D” or “A” for epoxy sealed version. Use AZ21511 for Pin 6 style.
