Altech Corp. – a New Jersey-based supplier and distributor of electronic and control components, including for the wind industry – has rolled out a new line of UL ground-fault equipment protection (GFEP) devices.

According to the company, the technology enables the reliable protection and operation of equipment wherever and whenever ground faults may occur. In all three series, ground-fault sensitivity levels range from 10 mA to 500 mA.

The devices are designed to prevent costly production shutdowns due to AC and DC pulsating ground faults, as well as overloads and short circuits.

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 the need for upstream circuit protection.

Next, the UL 1053 ground-fault sensing and relaying device (GF Series) provides residual current protection for circuits with loads up to 63 A. It represents an ideal retrofit GFEP where standard overload and short circuit protection is already being provided by other means, the company explains.

Lastly, the UL 1077 ground-fault relay with overload protection (GFR Series) serves as a combined equipment ground-fault relay and supplementary protector, the company says.
