3037643

Engineered for mission-critical applications, the 3037643 by Phoenix Contact delivers superior performance in Terminal Blocks - Accessories - Marker Strips systems. This innovative marker strip incorporates graphene-enhanced polymers that provide 40% higher tensile strength than conventional materials while maintaining exceptional dielectric properties for high-voltage environments.The Marker Holder variant features a unique interlocking design that prevents accidental disengagement in high-vibration settings. When compared to standard marker strips, this configuration demonstrates 3x greater retention force in MIL-STD-810G shock tests.Validated for seamless integration with CLIPLINE ST Series, this solution reduces wiring errors by 52% in complex control panels. The backward-compatible design supports both legacy and next-generation terminal blocks.The Gray formulation utilizes quantum dot technology for enhanced visibility in low-light conditions. This chromatic innovation improves maintenance efficiency by 29% in underground mining applications.
