Square D Current Transformers are available in General Purpose Round, Toridal, Bushing, Rectangular, and Split Core configurations.
- General Purpose Round Current Transformers - Specifically designed for ammeter and solid-state transducer applications. Design allows for low cost compact solution with good electrical performance.
- Toridal Current Transformers - Extremely wide range of ratios available, along with wide range of window sizes from 1.13 in (28 mm) to 8.13 in (206 mm).
- Rectangular Current Transformers - design for bus conductor applications instead of wire; 2 window sizes.
- Split Core Current Transformers - Design for easy installation over existing bus or cable connections; available in 2 configurations.
- Bushing Current Transformers - Designed to be installed into breaker cradle, allowing bus to be centered in the CT allowing potential to stay below 600V even in medium voltage applications.
Square D offers 3 models of voltage transformers:
- 450R: Designed for accurate voltage measurements with 0.3 accuracy; designed for switchboard use with a wide range of electrical indicating, recording instruments and protective relays in power systems
- 460R: Designed for voltage indication with lower accuracy and smaller burdens; designed for use with voltmeters, transducers and other types of electrical indicating and recording instrumentation
