Compact design and space efficiency are core features of the ABB 1SVR405651R4100 socket. The 16 mm width, 69 mm height, and 76 mm depth enable dense panel layouts, delivering a measurable reduction in cabinet footprint while maintaining robust mechanical fit. This translates to faster installation and easier field service in multi-channel automation racks. The screw-terminal wiring enhances connection security and simplifies field rewiring, reducing maintenance interruptions and error rates during live operations. With a rated output of 250 V at 5 A and a control supply of 220 V DC, it reliably drives common industrial loads while staying within standard control-circuit practices. The 2 c/o SPDT configuration gives flexible signal routing for control logic and interlocks, supporting streamlined wiring diagrams and quicker diagnostics. Compatibility with pluggable function modules, holders, and markers accelerates customization and improves traceability in complex control schemes. Certifications and RoHS compliance minimize compliance risk and simplify supplier consolidation for OEMs and integrators. The overall design supports quick swaps, modular upgrades, and scalable architectures in modern automation plants.
