Current transformers with integrated transducer

Product catalog summary
Overview: This document provides comprehensive technical specifications and selection guidelines for current transformers (CT) with integrated transducers, designed for measuring alternating current (AC) and converting it into a standard 4-20mA output signal.
Specifications: The CTs offer selectable primary current ranges from 5A to 6000A, with a passive 4-20mA output and a two-wire connection. They have an accuracy class of 1, a response time under 200 milliseconds, and a residual ripple of less than 1% peak-to-peak. The devices can handle continuous overloads of 1.2 times the nominal current and short-time overloads of 20 times the nominal current for 1 second. They operate within a frequency range of 45-65 Hz, consuming less than 0.5VA in current circuits. The operating temperature range is -10°C to +50°C, with a storage range of -30°C to +70°C. The housing is made of self-extinguishing thermoplastic material, compliant with UL 94-V0 standards, providing full galvanic insulation. The overvoltage category is CAT III 300V and CAT II 600V, according to EN 60688 standards.
Product Variants: Various models are available with different dimensions and selectable ranges. For instance, the MAC022 model supports ranges from 5A to 30A with a cable diameter of 22mm. Other models like MAC017, MAC032, MAC040, MAT061, and MAT101 cater to different installation requirements.
Installation and Accessories: Each CT model includes a range selector and sealable terminal covers. Accessories such as fixing sets for busbar mounting and protective caps for fixing screws are provided. Wiring diagrams are included for installation guidance.
Special Executions and Options: Additional charges apply for special executions and options, including different accuracy classes and additional accessories.
Conclusion: This document serves as a detailed guide for selecting and installing current transformers with integrated transducers, offering all necessary technical data and installation instructions.
Additional Specifications: The document also details specifications for an A.C. current transducer with an integrated CT, including input types like sinusoidal and TRMS, with ranges from 0-5 A to 0-100 A. Output options include 0-5 mA, 0-20 mA, 4-20 mA, 0-10 V, and RS485 Modbus RTU. Auxiliary supply voltage options range from 115/230Vac to 380/415Vac.
Ordering Codes: Ordering codes for different configurations and options are provided, with instructions on completing the code. For unlisted values, contacting FRER for feasibility is advised.
Options and Special Executions: Special executions are available with specific overprice codes, including M3 screw terminals, accuracy class 0.5%, 400Hz operating frequency, 50msec response time, 4kV insulation level, zero and full scale setting, tropicalization, ship mounting, and versions for H2S, NH3 applications. Each option is linked to a specific product type code.
Recommendations: For unlisted options, contacting FRER sales staff is recommended to evaluate feasibility.
