1920956

Phoenix Contact's 1920956 redefines ruggedization in Terminal Blocks - Accessories components, developed to withstand 50G mechanical shock pulses while maintaining electrical continuity. Its programmable logic survives 100kRad total ionizing dose for nuclear power plant instrumentation.The Cable Housing variant employs ceramic-filled PPS insulation that maintains dielectric properties up to 250 C, exceeding IEEE 383 requirements for Class 1E nuclear safety systems.With 5 hermetically sealed contacts, this solution prevents gas permeation in oil-filled transformers while supporting 200A continuous current per position.When integrated with COMBICON GMSTB, IC and MSTB Series, the assembly passes MIL-STD-810H salt fog testing with zero corrosion after 1000 hours exposure.The Black coding system incorporates photoluminescent markers that remain visible for 8+ hours in complete darkness, crucial for emergency power system maintenance.
