Industrial 2303-600AMPS-TRANSFORMER Transformer

The Simpson Electric 02303 Donut Current Transformer is an industrial current-sensing device that measures AC current by passing a single conductor through its toroidal core, producing a 600:5 (120:1) ratio with a 2 VA burden and is intended for use with panel meters and control instrumentation. It handles up to 600 A in the primary while delivering a 5 A secondary output, a configuration consistently listed by distributors as a standard Simpson part for high-current monitoring in electrical panels, switchgear, and energy-management systems. This donut transformer operates over a broad frequency range from 50 Hz to 400 Hz and is offered with Class 2 accuracy, making it suitable for 50/60 Hz installations and select 400 Hz applications without overloading the secondary circuit. For easy integration, the unit includes approximately 9 ft of leads and its 5 A secondary compatibility aligns with common panel-mount meters and data loggers, providing a reliable, indirect current measurement solution in industrial environments.
