Product catalog summary

Specifications:
The split core current transformers (CTs) are designed for frequencies of 50/60 Hz, with optional ranges from 16 2/3 to 400 Hz upon request. They support nominal voltages up to 720 V AC, and up to 1200 V AC for specific models (ASK 165.5, 205.5). The isolation class is E, with test voltages of 3000 V and 6000 V for different nominal voltage ranges. The thermal current is continuous at 1.0 × In, and 1.2 × In for certain models. The rated short-time thermal current is 60 × In for 1 second, with a maximum of 100 kA. The dynamic current is 2.5 times the thermal current. Operating temperatures range from -5°C to 50°C, and storage temperatures from -25°C to 70°C. The CTs comply with IEC/DIN EN 61869/1+2 and DIN 42600/1+2 standards.

Product Variants:
The document details various models such as KBU 23, KBU 58, KBU 812, and KBU 816, each with specific primary nominal currents and dimensions. The primary conductor sizes and weights vary across models, with options for round conductors. Security factors range from FS 5 to FS 10 depending on the current rating.

Mounting and Accessories:
CTs can be mounted using foot angles for screw mounting or busbar mounting screws with isolating protection caps. DIN-rail mounting is available for certain types. Optional accessories include test certificates, sealed shutters, excitation curves, and cast resin for CTs with nominal currents below 4000A.

Additional Features:
Optional frequency ranges and cast resin options are available upon request. The document emphasizes the availability of customizations and additional features based on specific requirements.

Current transformers Test certificate On request, we can provide you with a test certificate for a specific current transformer along with the CT. Please inform us when placing your order. Sealed shutter On request, we can supply a transparent plastic cover. The cover seals the connections on the CT in a way that leaves the type label visible. Please check availability on each individual data sheet. Excitation curve On request, we can provide you with an excitation curve for a specific current transformer along with the CT. Please inform us when placing your order. Optional frequency Frequency...
