Product Brief:

150‑B180 is Emerson solid‑state soft‑starter unit for three‑phase squirrel‑cage motors. It realizes soft start and soft‑stop function, reduces inrush current impact to power grid and mechanical shock of load equipment. Supports voltage ramp, current‑limit start mode and pump anti‑water‑hammer function. Integrated multiple motor protection: overload, phase loss, phase unbalance, winding over‑temperature via PTC sensor. Local keypad‑display supports parameter setup, fault checking and status monitoring. Widely applied on fans, pumps, compressors and conveying machinery. This is EOL discontinued spare part. Please verify motor parameters and cabinet layout before purchase. Strict ESD anti‑static protection shall be followed during installation and replacement
