Applications |
submersible pumps, transport pumps, ground water pumps |

Description |
The motor protection plug is a combination of operating switch, motor protection, and level switch with manual/automatic changeover for pumps. A bimetal contact can be connected. Together with a floating switch, the contactor combination can be used for controlling the level of pumps. A floating switch connected at the switch controls the switch contactor. Under automatic operations, the floating switch actuates the pump; under manual operations, the floating switch is not in service. |
• contactor combination (0–1) |
• overload release |
• CEE plug with phase reverse can be directly inserted into a socket |
• rocker cover “seal cap” |
• position 0: pump not working |
• position I: pump running (manual operational mode) |
• position II: floatingswitch governs pump running (automatic operational mode) |
• reset overload protection: automatic |
• rotating field display red: indicates wrong phase position (change direction of rotation at the phase reverse) |
• bimetal contact connection possible |
