257-457

Optimized for automotive electronics, the 257-457 by WAGO Corporation sets new standards in Terminal Blocks - Wire to Board reliability. This vibration-resistant terminal block meets AEC-Q200 qualifications, making it ideal for engine control units and vehicle electrification systems. The 510KBA-BAAG's robust construction withstands temperature extremes and mechanical shock encountered in automotive environments.The 1 stacked design conserves valuable dashboard real estate. Automotive-grade interlocking features prevent level separation under 15G vibration loads.Providing 7 termination points, this configuration handles complex automotive wiring looms. Each position incorporates anti-fretting coatings that withstand 500+ thermal cycles.0.200" (5.08mm) spacing prevents arc-over in 48V mild hybrid systems. The flame-retardant housing material meets FMVSS 302 flammability requirements.Horizontal with Board installation accommodates constrained vehicle packaging. The angled variants enable wire routing around structural members without exceeding bend radius limits.Rated for 15 A load capacity, the terminal block powers critical vehicle systems. Copper alloy contacts maintain stable resistance despite on-road vibration and thermal cycling.The 300 V rating exceeds automotive electrical system requirements. Self-cleaning contact surfaces prevent oxidation buildup in high-humidity environments.Compatible with 12-28 AWG automotive-grade cables, the termination resists wire fatigue. The clamping mechanism distributes stress evenly across stranded conductors.Through Hole attachment meets automotive shock and vibration standards. Press-fit versions eliminate solder joints that could fail under mechanical stress.The Screwless - Push Button Clamp system enables quick assembly line installation. Weatherproof seals prevent moisture ingress while allowing visual inspection of proper wire seating.Push Button Actuated include IP67-rated environmental protection. The integrated secondary locking mechanism prevents terminal backing out during vehicle operation.Gray coding complies with automotive wiring standards for circuit identification. The high-visibility pigments remain legible after 3000 hours of UV exposure.
