Current transformers for energy management
Carlo Gavazzi has updated its existing portfolio of current transformers with new devices offering enhanced safety for a wider range of applications. The CTD series comprises four new models – one for cables and three for bus-bars - providing measurements from 40 to 1600A. They are compatible with all the company’s energy management products and digital panel meters, and suitable for both motor control and power control centres.
Designed for DIN-rail mounting and panel installations, the new CTDs can be attached to existing wire terminals, using multiple isolated screws on the secondary to ensure strong and reliable attachment to any bus-bar, with up to eight-wire connection. Easy-to-connect output and earth, together with sealable terminal-block covers, guarantee maximum safety protection.
Current transformer output can be bridged without changing connection of the secondary: this feature prevents output over-voltage during installation or maintenance.
All models offer Class 0.5 measurements to EN60044-1 standards. The CTD-1X is designed for cables and bus-bars up to 23mm diameter, with input rating up to 300A, whilst the CTD-2X, CTD-3X and CTD-4X devices are designed for 32x5, 51x15 or 64x20mm bus-bars, providing measurements of 40-600, 50-1200 or 150-1600A respectively. Secondary current ratings are 5A or 1A across the range.
Operational over the full -25 to +60 degrees C temperature range, the units offer protection up to IP20 standards with sealed terminal block covers and terminals.
