257-555

The 257-555 from WAGO Corporation is a high-performance Terminal Blocks - Wire to Board solution engineered for robust connectivity in demanding environments. This terminal block delivers exceptional signal integrity and power distribution capabilities, making it ideal for industrial automation systems. With its advanced contact technology and versatile configuration options, the 510KBA-BAAG ensures reliable wire-to-board connections across various applications.Featuring 1 level configuration, this terminal block provides flexible stacking options for space-constrained designs. When multiple levels are required, the interlocking mechanism maintains structural integrity while minimizing PCB footprint.With 5 positions available per level, engineers can achieve optimal contact density for complex wiring harnesses. The position count directly impacts current carrying capacity and thermal management characteristics.0.300" (7.62mm) center-to-center spacing optimizes creepage and clearance distances. The precision-molded insulator prevents arc tracking at elevated humidity levels.The Horizontal with Board design facilitates ergonomic cable routing in tight enclosures. Compared to standard vertical orientations, angled configurations reduce mechanical stress on wire terminations by up to 40%.Rated for 15 A continuous current, this terminal block exceeds industry standards for power transmission. Its proprietary alloy contacts maintain stable conductivity even under thermal cycling conditions.The 300 V voltage rating ensures safe operation in high-potential applications. Insulation materials are UL94-V0 certified for flame resistance and dielectric performance.Accommodating 12-28 AWG wire sizes, the termination system provides universal compatibility. Spring-loaded contacts automatically compensate for wire diameter variations while maintaining constant contact pressure.Through Hole installation method simplifies assembly processes while enhancing mechanical stability. Board edge variants feature anti-vibration locking tabs for mission-critical applications.The Screwless - Push Button Clamp mechanism enables tool-free installation with audible engagement confirmation. Compared to screw-type terminals, this design reduces installation time by 60% while preventing over-torque damage.Push Button Actuated enhance operational reliability in harsh environments. The integrated strain relief system prevents wire pull-out forces from exceeding 50N, ensuring long-term connection stability.The Gray housing provides visual differentiation for circuit identification. UV-stabilized polymer construction resists color fading even in outdoor applications.
