0-5A output [5VA rated] can drive long cables up to 50ft/15.2m, models from 0-100A right up to 0-10000A
The CTA3ph flexible current transformers are the world's first flexible 'clip-on' current probe with a 5A 5VA output, allowing compatibility with existing 5A metering circuits. Unlike conventional CTs, there are no open circuit hazards - ideal for retrospective metering projects and installations in confined spaces where installation of conventional iron core CTs is not possible. The CTA3ph 5A output Rogowski Coil current sensing, simplifies installation and eliminates the need for expensive LV/HV plant shutdowns. In addition, the CTA modules can be used to convert any voltage output current measuring device to a 1A or 5A secondary.
The CTA3ph flexible current transformers convert ac current to an isolated 0-5A current with available ranges from 100A to 10,000A. Because the current sensors are flexible split core, installation is possible without shutting down the LV electrical supply, avoiding expensive down-time costs. Typical applications are retrospective energy monitoring include hospitals, banks, offices buildings, where Energy Management, power, energy and current monitoring is important. For all CTA3ph current sensor models, a NIST/NPL (UKAS) traceable calibration certificate and certificate of conformance is supplied. All CTA3ph sensors use UL94V0 or CSA approved materials. The CTA3ph flexible current sensors are suited to permanent or semi permanent installation. The coil sensor is durable, lightweight, flexible and will easily clip-around a power cable - even in confined spaces. The 5A output from the CTA3ph current sensor connects direct to installed metering, rotary metering or current transducers.
