Altech intros UL 489 ground fault equipment protector to help prevent costly production shutdowns

By Paul Dvorak | December 7, 2016

A complete line of UL Ground Fault Equipment Protection (GFEP) devices from Altech Corp. – including an industry “first” – introduce ideal solutions to help prevent costly production shutdowns due to ac and dc pulsating ground faults, as well as overloads and (with some models) short circuits.  The technology lineup offers three highly engineered series of devices delivering multiple capabilities and promoting reliable protection and operation of equipment wherever and whenever ground faults may occur.  In all three series, ground fault sensitivity levels range from 10 to 500 mA.

The UL 489 Branch Circuit Breaker with Ground Fault Relay (GFL Series) represents an industry “first” by combining a Ground Fault Equipment Protector with a UL 489 Branch Circuit Protector, which eliminates a need for upstream circuit protection.  This device is available in 1 pole+N, 2 pole, and 2 pole+N configurations at 120/240 Vac and 240 Vac. Rated current is 5 to 40A and rated Short Circuit Interrupt Capacity is 10 kA.  Three trip curves (B, C, and D) can be specified.

The UL 1053 Ground Fault Sensing and Relaying device (GF Series) provides residual current protection for circuits with loads up to 63A.  This model is designed with 2 and 4 poles at 277 Vac and 480Y/277 Vac, rated current of 25A, 40A, and 63A, and rated Short Circuit Withstand Capacity of 10 kA.  This device represents an ideal retrofit GFEP where standard overload and short circuit protection is already being provided (or will be provided) by other means.

The UL 1077 Ground Fault Relay with Overload Protection (GFR Series) serves as a combined Equipment Ground Fault Relay and Supplementary Protector (RCBO). The device can be supplied with 2 and 4 poles at 277 Vac and 480Y/277 Vac and with a rated current of 5 to 40A.  Rated Short Circuit Withstand Capacity is 10 kA and three trip curves (B, C, and D) are offered.

These three series are the latest additions to Altech’s UL listed product range dedicated to meet the most demanding conditions and applications across industries.  Altech further provides comprehensive product support and the capability to develop customized solutions to meet particular requirements.
