Littelfuse Announces New Motor Protection Relays for Low-Voltage Motors
New line of POWR-GARD® motor protection relays reduces installation time, simplifies retrofits and occupies less panel space
2010-11-02 12:00:00CHICAGO, Illinois, October 20, 2010 – Littelfuse, Inc. announced today that it is adding three new products to its POWR-GARD Protection Relay product line, the PGR-6130, PGR-6150 and PGR-6800. The new products economically protect industrial motors and pumps from damage caused by heavy operational cycles, overloads and jams. Current transformers (CTs) are integrated into all of the new Littelfuse motor protection relays, eliminating the need for external transformers, which saves installation time, space and simplifies retrofitting.
The new motor protection products are designed to address the needs of general industrial facilities utilizing low- to medium-horsepower motors and pumps. “As organizations are now operating with leaner staffs, we see a continuing trend to reduce maintenance costs and simplify installations. At the same time, customers want increased safety and efficiency. Our new motor protection relays meet those needs by offering proven reliability and a full range of features,” said Tony Locker, P.E., Product Manager for Littelfuse Protection Relays.
According to the National Electrical Manufacturers Association (NEMA), for every 8 to 10 degrees Celsius that a motor runs above its recommended operating temperature, its life expectancy is cut in half. Locker said, “Our motor protection relays can extend motor life by preventing overheating, which, according to NEMA, is one of the most common causes of motor failure.”
Littelfuse protection relays also prevent unscheduled shutdowns and lost productivity by detecting harmful electrical conditions before damage occurs. “Real-time monitoring is the new preventive maintenance. End users now demand products with predictive capabilities that allow them to take action before an unscheduled shutdown,” says Locker. In addition, by identifying problems in advance, protection relays improve operational safety by reducing the risk of fires, Arc-Flash incidents, and injury to personnel.
The PGR-6130 relay offers advanced motor-overload protection designed for low-voltage, low-horsepower motors. This compact device with integrated current transformers replaces older style overloads and provides more reliable protection.
The PGR-6150 is a standard motor-protection relay with an optional interface for remote operation that provides protection for low-voltage, low- to medium-horsepower motors. Ultra compact, these relays protect motors from overload, undercurrent, overcurrent, jam, overtemperature, phase loss, phase reverse, and phase unbalance.
The PGR-6800 pump protection relay protects low-voltage, low- to medium-horsepower pumps from pump-specific functions such as undercurrent and can be used to replace and consolidate older relays and low-level sensors.
Availability
The PGR-6130, PGR-6150 and PGR-6800 motor protection relays are available from stock.
