Littelfuse SymCom 201-100-SLD Seal Leak Detector

Littelfuse SymCom 201-100-SLD Seal-Leak Detector is an 110-120VAC 8-pin plug-in style seal leak detector to sense seal failures on submersible pumps. The unit plugs into an OT08-PC or RB08-PC octal socket (sold separately).

When the unit is powered and the resistance from the probe is greater than the sensitivity control level, the internal relay contacts change state. As water leaks into the motor seal, the resistance measured by the probe decreases. When the resistance drops below the sensitivity control level, the unit will trip and the relay contacts will change back to their original state. The unit will automatically reset when a fault is cleared.
