- Connection for remote alarm command (C11-C12) (float, pressure switch or others).
- Protection against short circuits through motor circuit breaker.
- Protection against overloads through motor circuit breaker.
- Thermal trip indication (motor-circuit breaker handle positioned at 45º - “Trip” position)
- Indication of alarm on (red light).

Como Funciona

After making all the connections correctly, the motor circuit breaker must be adjusted according to the nominal current of the motor. If the motor-circuit breaker handle is in the automatic operation position (1), the pump switches on/off depending on the closing or opening of the external start/stop command.

Whenever the alarm command (C11-C12) closes, the alarm signal (red signal light) and the audible alarm will be turned on, which can be turned off using the respective switch.

Tripping of the motor-circuit breaker due to a short circuit or overload switches off the pump, regardless of the state of any of the controls. The position of the handle on the motor-circuit breaker makes it possible to differentiate when it has been turned off by manual action (horizontal handle - Position “0”) or by failure (handle at 45º - Position “Trip”).
