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