WAGO 821-104 4-pólový THT svorkový blok pre DPS, Push-button CAGE CLAMP, rozteč 5 mm, svetlosivá

The WAGO 821-104 is a high-quality 4-pole PCB terminal block featuring the innovative Push-button CAGE CLAMP® connection technology. Designed for through-hole (THT) mounting with a 5 mm pin spacing, this component ensures reliable and maintenance-free wiring for a wide range of industrial and electronic applications. The front-entry wiring and push-button actuation allow for fast, tool-free conductor insertion, making it ideal for automated assembly and field wiring.

Advantages

Push-button CAGE CLAMP® technology enables effortless, vibration-proof connections without special tools. The compact design saves valuable PCB space, while the light gray polyamide housing with orange actuation buttons provides clear visual identification. Rated for 320 V and 12 A, it meets stringent safety standards with UL94 V-0 flammability rating and supports solid and fine-stranded conductors from 28 to 12 AWG.
