Description
The FICO FCT-25SDK Palm is a specialized variation of the 25SDK series, featuring a dual-core configuration and high-conductivity “Palm” primary terminals. This indoor current transformer is vacuum-cast in premium epoxy resin, offering superior dielectric strength and mechanical durability for 12kV power systems. Its dual-core design is specifically engineered for simultaneous high-precision revenue metering and reliable relay protection, making it a versatile component for utility and industrial switchgear.
Key Features & Technical Specifications
Dual-Core Versatility: Contains two independent magnetic cores to provide separate signals for measurement and safety systems:
Core 1 (Protection): 100/5A, 15 VA, Class 5P20 (Terminals 1S1-1S2)
Core 2 (Metering): 100/5A, 10 VA, Class 0.5M5 (Terminals 2S1-2S2)
Palm Terminal Interface: Equipped with flat, vertical “Palm” primary connectors that ensure a large surface area for secure, low-resistance bolting to busbars.
Insulation Excellence: Rated for a maximum system voltage (Um) of 12 kV with a certified insulation level of 12/28/75 kV, ensuring safety against high-voltage surges.
Short-Circuit Protection: Capable of withstanding a Short-Time Thermal Current (Ith) of 20 kA for 1 second.
Compliance: Fully compliant with IEC 61869-1/2 international standards.
Industrial Build: Manufactured in 2025 with a “Property of K-E” (K-Electric) designation, indicating its readiness for utility-grade infrastructure and long-term service (Warranty up to 2027).
Terminal Safety: The secondary terminal block is protected by a clear, bolt-on transparent cover, ensuring secondary earthing points are visible and secure.
Safety Reminder: One secondary terminal must be earthed during service. Never leave the secondary winding open-circuited while the primary is energized, as this can lead to core saturation and dangerous voltage levels.
