The third, unswitched leg is bussed through the unit for convenient connection.
These economical DIN rail or wall mount 3 phase
SSC units are designed to control resistive 3 phase loads, such as heater bands and cartridge heaters, using the DC or AC SSR driver output from a temperature controller. Using noise-free zero cross firing, the 7PE, 7PB and 7PF control 2 legs of the resistive 3 phase load. The third, unswitched leg is bussed through the unit for convenient connection.
