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

Compare OPA-B and OPA-H single phase openwell level-control starter panels. OPA-H is the listed built-in MCB variant; do not assume both models have the same components. Check the exact model's motor current, timer and control functions, trip settings and power-return behaviour. MCB availability does not determine every isolation requirement. Final wiring and settings should be checked by a qualified electrician using the exact product manual.
