The Littelfuse 777-AccuPower is a fully-programmable 3-phase motor and pump protection relay. It allows motor hp rating, full load amps, efficiency and power factor to be entered and will accurately calculate motor output power. This is most useful with mag-drive pumps or process applications where the process power is desired over the utility power. Voltage, current and power measurements can be displayed as well as fault information and setpoints. The built-in display simplifies troubleshooting and allows the user to easily and precisely configure setpoints. The Littelfuse 777-AccuPower can be used with the optional COM 4-20 output module to give an analog signal proportional to output shaft power, the RS485MS-2W (for limited Modbus capabilities, and for use with the RM1000/RM2000) remote displays listed in the 777 accessories section.

Littelfuse PC-102CICI-DL:

Dual seal-leak detector uses inputs to sense seal failures and energize the output relay. Input logic direct or inverted is DIP switch selectable.

Littelfuse PC-102CICI-LT:

Seal-leak and over-temperature detector uses one input to sense seal failures and the temperature input to detect motor overheating. Configurable to suit various probes. Seal input logic direct or inverted, plus over-temperature trip reset automatic or manual, is DIP switch selectable. 

Littelfuse PC-102 Pump Protection Controller

Littelfuse PC-102 Description

The LIttelfuse 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.

The Littelfuse PC-105 is a 5-channel pump controller designed to handle multiple pump applications. Alternatively, it can operate as a 5-channel switch. The Little Fuse PC-105’s control functions support all of the popular industry standard multi-pump pump-up and pump-down configurations. It can indicate low, high and out-of-sequence alarms and use alternating and non-alternating pump control. The non-alternating pump can be used as a jockey pump or emergency pump. Using the built-in DIP switches, individual pumps can be disabled when taken out of service for repair or maintenance.

Pump Control from Littelfuse - PC-XXX-LLC Series

 Pump Control from Littelfuse in Small Package - Octal Socket

The Littelfuse PC-xxx-LLC-CZ and PC-xxx-LLC-GM series are liquid level control relays used to control conductive liquid pumping operations in a pump-up or pump-down application. The units come in two different voltage ranges (see specs below). The units have an adjustable sensitivity knob (4.7 k to 100 k ohms) that is set according to the resistance level at which you want the probes (sold separately) to sense the conductive liquid. The units have a built-in debounce time delay that prevents the relay from energizing if the probe resistance momentarily goes above or below the sensitivity set point (due to liquid splashing in the tank). The Little Fuse units operate their internal relay based on inputs from a high and low probe and a common reference (when a conductive tank is used) or common probe (when a non-conductive tank is used).
