Description
The FICO FCT-D32 is a specialized, triple-core indoor current transformer designed for seamless integration within NX Air switchgear and modular medium-voltage panels. This unit is vacuum-cast in high-grade epoxy resin, providing a compact yet powerful solution for complex monitoring requirements. By featuring three independent secondary cores, the FCT-D32 allows for simultaneous high-precision metering and multi-level relay protection, making it a critical component for sophisticated industrial power management.
Key Features & Technical Specifications
Triple-Core Configuration: Engineered with three distinct secondary windings to handle different system requirements simultaneously:
Core 1 (Protection): 100A, 15 VA, Class 5P20 (Terminals 1S1-1S2)
Core 2 (Protection): 100A, 15 VA, Class 5P10 (Terminals 2S1-2S2)
Core 3 (Metering): 100A, 10 VA, Class 0.5M5 (Terminals 3S1-3S2)
NX Air Optimized: The form factor is specifically designed to meet the strict spatial and dielectric clearances of NX Air cubicles.
High Short-Circuit Strength: Rated for a Short-Time Thermal Current (Ith) of 25 kA for 1 second, ensuring the unit survives extreme electrical faults.
Superior Insulation: Provides a maximum system voltage (Um) of 12 kV with a tested insulation level of 12/36/95 kV.
Compliance & Reliability: Manufactured according to IEC 61869-2 standards, ensuring global interoperability and long-term mechanical stability.
Secure Terminal Block: Features a 6-terminal secondary interface (1S1 through 3S2) clearly labeled for error-free wiring of protection and metering circuits.
Robust Mounting: Equipped with a galvanized steel base plate with wide mounting slots for secure vibration-resistant installation.
Safety Protocol: One secondary terminal must always be earthed during service. Never leave a secondary winding open-circuited while the primary current is flowing, as this can generate dangerously high voltages.
