Rittal 9393553 Current Transformer - EN 61869-1/2

EN 61869-1/2 compliance and an accuracy class of 0.5 deliver high-precision current sensing, translating into lower relay misoperation and tighter energy accounting. This improves protection relay performance in distribution panels and supports accurate data for energy management systems in industrial facilities. With a primary current rating of up to 300 A and a 333 mV secondary burden, it enables reliable measurements for medium-scale power distribution and motor control centers, reducing the need for separate transducers and simplifying panel layouts. The compact form factor (60 × 80 × 30 mm) allows easy integration into standard Rittal enclosures, saving space in crowded control cabinets and enabling streamlined wiring. The polyamide body with UL 94 fire protection provides a robust safety margin in harsh environments, supporting compliance with fire-safety requirements in electrical cabinets. Supplied hardware—including two plug-in feet, two insulating caps, one primary bar clamp, and two grub screws—facilitates fast, secure mounting and minimizes field assembly time. A conductor range of 0.5–2.5 mm² and 50/60 Hz compatibility give you flexible wiring options across mixed-system installations while maintaining measurement integrity. The device’s operating temperature range (-5 to 55 °C) and storage range (-25 to 75 °C) with 10–90% non-condensing humidity ensure reliability in industrial environments, even under temperature and humidity fluctuations. Packaged as a single unit, it simplifies procurement and stock management for maintenance schedules and project rollouts.
