Altech introduces  UL Ground Fault Equipment Protection

December 7, 2016 - A complete line of UL Ground Fault Equipment Protection (GFEP) devices from Altech introduce solutions to help prevent 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 series of devices delivering multiple capabilities and promoting protection and operation of equipment wherever and whenever ground faults may occur.  In all three series, ground fault sensitivity levels range from 10 mA – 500 mA.

The UL 489 Branch Circuit Breaker with Ground Fault Relay (GFL Series) combines 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 120/240V AC and 240V AC.  Rated current is 5A-40A and rated Short Circuit Interrupt Capacity is 10kA.  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 277V AC and 480Y/277V AC, rated current of 25A, 40A, and 63A, and rated Short Circuit Withstand Capacity of 10kA.  This device represents an 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 277V AC and 480Y/277V AC and with a rated current of 5A-40A.  Rated Short Circuit Withstand Capacity is 10kA 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 demanding conditions and applications across industries.  Altech further provides  product support and the capability to develop customized solutions to meet particular requirements.
