About WAGO Spring-Clamp Terminal Blocks and I/O

WAGO built its catalogue on one idea: terminate the conductor with a spring instead of a screw. The CAGE CLAMP and later push-in variants hold the wire under constant spring force, so the joint does not need re-torquing after thermal cycling and does not loosen under vibration, and installation is a matter of pushing in a conductor or lifting a lever rather than setting a torque figure. That principle runs through rail-mounted TOPJOB S terminal blocks in feed-through, ground, fuse, disconnect and multi-level versions, through PCB terminal blocks and pluggable field wiring, and through the compact lever and push-wire installation connectors used for splicing and luminaire wiring. Alongside the passive range sit relay and optocoupler modules, interface and marshalling systems for controller I/O, DIN-rail power supplies and UPS modules, and the WAGO-I/O-SYSTEM: a fieldbus coupler or controller carrying a row of slice I/O modules and closed by an end module. Article numbers are a series prefix, a hyphen and an item number, as in 750-842 or 2202-1611, with further groups after a slash denoting colour, marking or a factory variant.

WAGO Spring-Clamp Terminal Blocks and I/O in Saudi Arabia

The maintenance argument for spring termination is stronger in Saudi Arabia than in a temperate climate. Panels in outdoor kiosks, pump houses and unconditioned substations swing through a wide daily temperature range for most of the year, and screw joints on stranded conductors relax under that cycling, which is why re-torquing terminal strips appears on so many local preventive maintenance schedules. A spring joint removes that task. The same reasoning applies on skid-mounted compressors, crushers and conveyor drives where vibration is constant. In practice these products turn up in water and wastewater SCADA, remote pump and lift stations, desalination plants, cement lines, food and beverage plants, and building and utility automation on the large construction programmes at NEOM and along the Red Sea coast. Supply is 380/400 V at 60 Hz from SEC networks, controllers are usually 24 V DC fed, and imported goods are subject to SASO conformity assessment.

Ordering and lead time

Quote the WAGO article number in full and include every group after the slash. A suffix such as /1000-541 marks a different colour, marking print or factory variant, and dropping it will produce a physically similar block that does not match the rest of the strip. Terminal blocks are catalogued per piece but often packed in bags, so give us the piece count you need and we will confirm the pack size. End and intermediate plates, jumpers, marking strips and mounting carriers are separate articles and are the parts most often left off a rebuild list. For the I/O system, state the fieldbus of the coupler or controller, list each I/O module by its own number, and include the end module, since a node will not run without it. Items on this page are sourced to order and delivered duty-paid, with a normal lead time of about three weeks from order confirmation.
