Collection: Single Phase Fully Automatic Openwell Submersible Starter Panel with Motor Protection & Cyclic Timer

Compare four single phase cyclic-timer openwell starter panels: OPM-C, OPM-H, OPM-V and OPM-W. OPM-V and OPM-W add an indicator for full/empty tank status, not a continuous sump-depth measurement. OPM-H and OPM-W are the listed built-in MCB variants. Level indication is different from automatic tank-level control. Match motor current, timing, protection and restart settings to the exact model, with installation by a qualified electrician.
