Current Transformers and DC Shunts

A voltage or current transformer is a type of electrical transformer that is designed to provide a secondary current that is accurately proportional to the primary current flowing. They reduce high primary currents down to a consistent 5- or 1-Amp secondary current. A DC shunt is a device that provides a low-resistance path for direct current (DC) and primarily used in rail and marine applications.

Current transformers and shunts are used in both single and three-phase systems. Small current transformers are used on printed circuit boards for the purpose of sensing current overloads, detecting ground faults, and isolating current feedback signals. Shunts are used in motor control, rail and marine applications.

Product Overview

Current Transformers and Shunts

Current transformers: to reduce high primary currents down to a consistent 5- or 1-Amp secondary current. Options include molded case width, busbar and aperture sizes, tape wound, 3-in-1, balanced and split cores, current ratings and various mounting options.

 

Shunts: to provide accurate dc millivolt signal, exactly proportional to the system current, to drive ammeter indicators, overload protection and control devices. This range includes industrial, switchboard, DEF 66-13, DIN, base mounted, tag end, lightweight and panel meter shunts in a variety of formats and configurations.
