Jobsites that lack durable, dependable protection relays put personnel at risk for injuries from electrical faults. Additionally, productivity falls when machinery, pumps, and motors fail due to overvoltage events, arcing, or short circuits that electrical current relays would have prevented. Littelfuse provides the full range of solutions. Manufacturers, construction companies, mining and fossil fuel operations, and solar power providers rely on Littelfuse relays, relay software, ground-fault circuit interrupters (GFCIs), and ground-fault, time-delay, and intrinsically safe relays to control essential equipment.
Motor and pump protection relays prevent damage and stalls from overloads, jams, phase loss, unbalanced loads, heavy starts, overheating, undervoltage, and excessive operational cycles. The units also help ensure efficiency. Littelfuse makes multifunction relays for single-phase, three-phase, low voltage, and medium voltage motors and pumps. As optional devices justify their cost by limiting rewinds, reducing downtime, and extending the lives of motor and pumps...
