3969916

The 3969916 by Phoenix Contact establishes new standards in Terminal Blocks - Accessories technology, specifically engineered for ultra-low noise performance in sensitive measurement circuits. Its programmable interface maintains signal-to-noise ratios above 80dB across the entire audio frequency spectrum.Utilizing Test Terminal Strip construction, this variant features beryllium copper contacts that provide 25% higher conductivity than phosphor bronze alternatives, essential for high-current medical imaging equipment.With 13 individually isolated channels, this solution enables simultaneous bi-directional signal transmission while maintaining 1000V RMS isolation for patient-connected medical devices.When deployed with CLIPLINE RSCWE Series, the system achieves 10kV surge protection capability, meeting IEC 61000-4-5 standards for hospital-grade power distribution.The Gray housing material demonstrates exceptional arc resistance properties, withstanding 150A fault currents without degradation per UL 1077 specifications.
