Split-Core Transformers: Common Features

Modern split-core transformers are easily installed, easily connectable devices that can be attached to virtually all types of wiring terminals. Preferably, a split-core transformer is attached to electrical wiring by snapping the device around the conductor. High quality split-core transformers—such as those produced by Magnelab—have the highest standards in terms of interleaving joints and self-locking mechanism. Typically, these products have a rated accuracy of +- 1 percent between 10 and 130 percent of their graded input.

Frequent applications of split-core transformers include power meters, control panels, general sets, switchgear, and distributed measurement systems. Installation is easy and takes only a few moments, and the specifications are easy to read. The device is able to withstand normal cold and heat conditions, but should not be left under direct sunlight for best results.

Regular features of split-core transformers include: rated input of up to 600 amperes (A), output of 5 A at rated current, frequency range of 50/60 Hertz (Hz), protection level 6.5 voltage power (Vp) Bipolar, and accuracy class 3 up to 2.5 volt-ampere (VA). These usually come with a warranty of up to seven years.

High quality split-core transformers are recognized by Underwriters Laboratories (UL) and compliant with Conformité Européenne (CE) and Restriction of Hazardous Substances (RoHS) standards.
