The 2-leg/3-phase SGB range relays are designed for controlling three-wired, three-phase loads connected in delta or, if balanced, connected in wye without neutral connection. Two of the three phases are switched by the SSR, the third being directly connected. With this range you have lower dissipated power (1/3 less) than with standard three-phase range.
Its key features include: three-phase zero cross solid state relay with one direct connection designed for resistive loads; high efficiency back-to-back thyristors on output with TMS² technology for a long lifetime expectancy; 24 to 600 VAC; high surge current; control range: 10-30 VDC; green LED visualisation on the input.
