TO3-04

Eaton - Electronics Division's TO3-04 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 Cover 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 4 hermetically sealed contacts, this solution prevents gas permeation in oil-filled transformers while supporting 200A continuous current per position.When integrated with CB3 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.
