Crucial Solutions for Critical Infrastructure

Protect water/wastewater operations with industrial GFCIs and fuses, arc flash detectors, and intrinsically safe relays made by Littelfuse. We design and deliver waterproof and vibration-resistant electronic components for pumps and motors at lift stations, water towers, and wells. We also provide controls for warning lights and time-delay relays for odor control systems at water treatment plants.

Residential Wells

Residential well pumps are susceptible to damage due to fluctuations in water supply. When groundwater is low, submersible pumps are at risk of dead head, rapid-cycle, and overvoltage/overcurrent conditions. Littelfuse PumpSaver constantly monitors the pump and prevents damage.

Case Study: Bee Cave Drilling Utilizing Littelfuse Pump Savers

Success Stories

Case Study: Bee Cave Drilling Utilizing Littelfuse Pump Savers

One customer completely trusts Littelfuse MotorSaver® after experiencing a phase-loss situation on a 200 hp motor. The customer had upgraded and installed a 201A-AU protection relay for the motor. The Littelfuse relay saved them from replacing their $30,000 motor and kept their de-rag operation from going offline and instantly backing up the entire treatment plant and spilling waste in multiple locations.

Increased Safety with MP8000 Bluetooth Relay

Municipal Water Wells

The city of Roswell, GA wanted to automate the process of collecting data from 250hp pump motors at their water wells. Previously, workers went to pump station, opened electrical cabinet, and manually tested equipment to log voltage and current measurements.

As a solution, the city installed MP8000 Overload Relays. The Relay's Bluetooth wireless connection lets workers monitor relay from their smart phone, while MP8000 app automatically collects time-stamped data. Remote monitoring increases safety by not opening cabinet and exposing workers to arc-flash hazard. The MP8000's digital logs increases data accuracy while saving time spent having to transcribe handwritten logs.

Maintain Power Quality with 355 Voltage Monitor

Pivot Load Controllers

A power company used voltage monitors used on irrigation pivots to protect from voltage variances. They had component failure with competitive voltage monitors in their load controllers.

The solution? The utility implemented the Littelfuse 355 Voltage Monitor to manage its heavy-duty applications. Today, the Littelfuse 355 Voltage Monitor continues to pay dividends in the form of protection and simple user-friendly diagnostics for the utility.
