Application The Type CLC is designed for high current metering on low voltage systems and is available in single or double ratios. It is suitable for use with un-insulated bus bar or cable up to 600 volts, or with insulated primary conductors at higher voltages. CLC current transformers are UL recognized - File No. E96461. Construction Features The ring type core and fully distributed winding are assembled to a glass filled polypropylene window liner and injection molded in thermoplastic rubber. Large clamp type terminals are equipped with slotted hex head tightening screws. A rotatable shorting bar is positioned on a center post located midway between the terminals. The center post also serves as a third terminal on double ratio transformers. A clear polycarbonate cover allows a visual check of connections. The cover is keyed to the shorting bar to insure proper installation and can be sealed with a sealing wire. Four piece mounting feet or single piece bases are available. These are constructed of marine environment resistant aluminum with an electrocoat and baked finish of gray acrylic paint. The CLC may also be secured to a wall panel or bracket by means of mounting holes through the transformer body. Micarta® window plates are used to change the window opening to a cruciform configuration, for direct bus bar sleeve mounting. Primary bar assemblies are available for converting the CLC to a bar type unit. These assemblies vary from a single bar for currents up to 1500 amperes, to a four bar assembly for 4000 amperes.
