ABS-Encased Current Transformer - Low Voltage - Window Type - Indoor Use
POS Series
Window-type current transformers in the POS Series, for 600-Volt or 0.72 kV power systems, feature a compact, lightweight ABS housing that enables flexible installation, even in tight spaces like motor control centers. Their high-quality coil and annealed core deliver rated accuracy per international standards. Primary connections suit busbar or insulated wiring. With up to 40 VA burden and 0.5, 1.0 or 3.0 accuracy class, these versatile CTs meet demanding application needs. The self-extinguishing ABS enclosure ensures safety. Top-facing terminals speed wiring while covers protect connections.

About the Product
The POS Series window-type low-voltage current transformers, intended for 0.72 kV or 600-Volt power systems, are appropriate for electric engineering applications and distribution switchgears. Every POS Series current transformer is contained in an ABS exterior (self-extinguishing) and encloses a high-quality coil, along with an annealed oriented core - all manufactured for rated accuracy and output. On the primary side, wiring can be done with a busbar or with insulated wire. Compact and lightweight, each of these current transformers can be installed either horizontally or vertically; in addition, the product is designed in such a way that installation in a smaller space (e.g. in a motor control center) poses no difficulty for secondary wiring or fastening the CT base. The range of Rated Burden is from 1.0 VA to 40 VA, and the Accuracy is Class 0.5, 1.0, or 3.0, depending on the Primary Ampere-Turn (AT). The POS Series products meet various international standards and have consistently earned a high level of customer satisfaction.
