Products include the MWP, WPK, WPJ, JWPF, and JWPS. www.jst.com LEM U.S.A. <strong>Inc</strong>. CTSR current transducers are for use in a range of safety-critical applications including solar installations. They accurately measure AC or DC residual or leakage currents, from 300 to 600 mARMS as nominal values, which can arise in fault conditions in a number of industrial or power-generation scenarios. Examples include solar panels that are coupled to a grounded distribution network, or in failure modes such as a short circuits or ground faults. The connection of a solar panel to the grid raises safety concerns; if a fault occurs there’s a potentially serious safety issue involving any human contact with the system. CTSR transducers measure the sum of all of the instantaneous currents flowing through their apertures, in single- or three-phase configurations, resulting in the residual-current monitored to ensure safety. www.lem.com Schurter <strong>Inc</strong>. Schurter’s quick-acting ASO fuse provides protection up to 1000 VDC, according to the latest gPV requirements. Offered with the FSO touch-safe fuseholder, the combination meets the needed robust circuit protection for the growing solar industry in a compact 10.3 mm x 38 mm size. Current ratings range from 1-30 A. www.schurterinc.com Semikron Semikron is a one-stop provider of silicon chips, discrete semiconductors, IGBT/SCR/Diode modules, IPMs, power assemblies, and systems for the solar market.
