281-344

The 281-344 by WAGO Corporation 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 Separator construction, this variant features beryllium copper contacts that provide 25% higher conductivity than phosphor bronze alternatives, essential for high-current medical imaging equipment.When deployed with DIN Rail Terminal Blocks, 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.
