Current Transformers POS Series The POS Series window-type low-voltage current transformers, intended for 600V (max.) 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. Specifications Standards: IEC, IEEE Rated Voltage: ≤ 0.72 kV Frequency: 50 / 60 Hz AC/BIL: 3 / - kV For indoor applications Self-extinguishing ABS exterior provides a high level of insulation and excellent moisture resistance Compact and lightweight – ideal for wiring and installation in smaller spaces Top-facing terminals for easy wiring Terminal covers (optional) Other Standards and Specifications available Selection Table * The Burden (VA) and its corresponding Accuracy (Class) are determined by the Primary Ampere-Turn (AT) of the Current Transformer. ** Primary Ampere-Turn (AT) = Primary Current (A) x Primary Turns (T).
