PC-102 Series - Dual Seal-Leak & Seal-Leak/Over-Temperature Detector

Littelfuse Pump Controls and Liquid Level Controls
The PC-102 series is a dual-channel switch that provides dual protection against seal failures and over-temperature in submersible pumping applications.


The relays have two form-C isolated output relays and two LEDs, which illuminate when each associated output relay is energized.


The sensitivity adjustment (4.7k-100kOhms) allows you to define the input impedance at which the output relays will change state. The sensitivity for the over-temperature detector can be set to 4k Ohms with use of the DIP switches.
