Altech® Introduces Industry ‘First’ UL 489 Ground Fault Equipment Protector Augmenting Complete Lineup to Help Prevent Costly Production Shutdowns
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 – unmatched in the industry – 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 mA – 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 120/240V 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 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 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 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.
THE ALTECH ADVANTAGE
In today’s very competitive marketplace you need reliability, so you need to use circuit breakers that are high quality and technically correct for your application. Altech is a US leader in DIN rail mounted breakers with ratings up to 63A. Only Altech offers DIN rail mounted breakers that meet UL489, UL508 or UL1077 approvals with a short circuit interrupt capacity of up to 10kA. No other manufacturer offers this complete line. This assures you the right product for your application requirements.
When you need branch circuit protection, Altech offers UL489 Miniature Molded Case Circuit Breakers in both AC and DC voltages. The AC version offers dual voltage rated circuit breakers at 0.2-63A/240VAC and 0.2-32A/480Y/277VAC in 1-3 poles. Altech is the only company that offers a 14kA, 20A C curve single phase breaker at 277V AC. The DC version offers 0.2-63A at 125V (1 pole) and 250V (2 pole).
If your application requires a manual motor controller, Altech is the leading US supplier of UL508 Manual Motor Controllers (MMC). In AC, we offer up to 60A in 1 to 3 poles at 480Y/277VAC. With 6 trip curves, Altech has the largest selection in the industry. This ensures you the selectivity you require for your application designs. Our MMCs have a 10kA short circuit withstand capacity, this is the highest rating in the industry. The AC version is rated up to 60A and is DC rated in 2 poles up to 80VDC.
When your application requires supplemental protection for control circuits and on the load side of branch circuit protectors Altech has solutions. We offer a competitive line of AC Supplementary Protectors, up to 63A, in 1 to 3 poles at 480Y/277VAC with a 10kA short circuit withstand rating.
