The TP3 Differential Level Switch is a float switch, which allows the automatic start and stop of the electrical equipment (usually pumps, but also electric control valves, alarms, etc.).
The main characteristic of this item is that it has a high reliability and its shape has no edges, for which it is particularly suitable to be used for sewage.
The item is made with double liquid-proof chamber, for the maximum reliability of the inside mechanism.3 Wire Differential Level Switch
Three wire differential level switches Close contacts Black and Brown on level rise. This connection is mostly used for de-watering, pumping out, low level protection and high level alarms.
Contacts Black and Blue close on level fall, and open on level rise. This connection is mostly used for Filling, pumping in and low level alarms.
If only two connections are used, the third connection should be insulated.
They are capable of starting or stopping small pumps or alarms directly, without the need for a control panel as they are rated at 4 Amps inductive 250V.
They are ideally suited for twin pump panels to suit automatic control of sewage and storm water systems with audible or visual alarms.
