This ground-fault sensing module functions interdependently with a magnetic branch-circuit breaker. The module monitors the electrical circuit by use of an external differential current transformer. With the company's GFCI solution, no direct load is present at the module and, in the event of a ground fault, the load is interrupted via the hydraulic magnetic circuit breaker using a shunt trip coil. Available with an automatic or manual “safe start” reset feature, the units are rated from 1A to 15A. When mounted with the supplied gasket, the enclosure achieves a UL NEMA 4X rating.
Rack-mount power conditioner
Designed to protect 120V systems, this rack-mount, low-impedance, isolation transformer-based power conditioner is available in three sizes rated at 8.3A, 12A, and 16A. Available with optional true rms voltage and current meters, the unit fits a standard 19-in. rack and uses 3U of rack space. In addition, it is suitable for equipment racks in laboratories or communications applications.
