You could run it at 1/3 capacity by simply connecting 1 phase and the return. If a three-phase motor is to be driven in only one direction, and upon its initial energization it is found to be rotating opposite to what is desired, all that is needed is to interchange any two of the three line leads feeding the motor. 165 x 170 x 145 SSR-3-ZC-2L-100 SSR-3S-ZC-3L-100 Three Phase Thyristor based 2 leg or 3 leg solid state relay module – suitable for 3 phase heaters connected in 3 wire Star or Delta configuration (31 to. Unlike the single-phase wiring scheme that must make a provision for a neutral leg and separate ground, the three-phase system needs neither a separate neutral nor a ground to operate safely. To install a 240V single phase circuit, just mount the 30A two pole circuit breaker in the metal tracks (designated for two hot busbars) which tightly holds the breakers. The delta-connected load will see a phase voltage that is the same as the line voltage, or 173.
