Summary of High currents, small spaces – a breeze for Wago 221
The Wago 221 series terminal blocks represent a significant advancement over the previous 222 series, offering a compact design that is approximately 40% smaller. Key features include full transparency for visual wire verification, dual-sided testing openings for versatile access, and lever mechanisms requiring less operating force. They support a wide range of wire types and sizes up to 4mm², handling high currents and voltages with multiple international approvals.
Parts used in the Wago 221 Series Terminal Blocks:
- CageClamp-S contact technology
- Transparent housing (dual-sided)
- Dual-sided testing openings
- Low-force operating levers
- Hollowed-out side wall grips
- Wire capacity range (0.14mm² to 4mm²)
- International approval certifications (ENEC, UL, PSE/JET, CQC, GOST-R)
Perhaps the hottest this-year novelty from company Wago – 221 series terminal blocks are here.
Not only in flyers and datasheets, but also in reality – in our stock. That´s why we bring you their description and mainly the first pieces to evaluate.
New series 221 is based on a well-proven technology of contacts – CageClamp-S and it´s partially similar to a favorite series 222, but 221 overcomes this previous series in many ways. Overall, the 221 excels in many aspects. Judge yourself:
● it´s about 40% smaller than series 222
● it´s fully transparent from both sides, thus enables easy visual control of a proper wire insertion
● testing openings are from both sides, what enables easy testing (for example by a multimeter) at various positions in installation boxes, motors,…
● a feelingly lower force is necessary to operate the lever, in comparison to series 222
● huge range of usable diameters from smallest (0,14mm2/0,2mm2), up to 4mm2
32A/450V/105°C – usable for 230V and also 400V applications
● possibility to use solid, stranded and fine-stranded wires
● international approvals like ENEC, UL, PSE/JET, CQC, GOST-R
● hollowed-out grips on the side walls for a better grip and easier manipulation during installation
