Brilliant, time-saving connectors for neat wiring
Very useful connectors for quick, clean wiring work. The levers make it easy to clamp conductors securely without tools, and they hold both solid and stranded wires firmly. Compact size helps keep junction boxes tidy and there is a clear housing to see the connection. A pack of 50 is ideal to have on hand and offers good value.

WAGO are the best, don’t buy cheaper versions
WAGO’s are the best connectors available. I think they are manufactured in Germany. There are cheaper copies of these, but I wouldn’t trust them. For just a little bit more money, these are brilliant bits of kit! They make a very positive connection on a wide range of thicknesses of wire and they’re easy to use and very quick. I also believe they can be used as a permanent connection behind plaster.

Great
Got these for a kitchen refurb. The ones I used were great and very handy, I'd like to see higher spec ones for using on high watt sockets for things like portable heaters and air fryers. So deducting a mark for that. Also like to see a screw in version for that not clips. But actually really innovated little product and fast delivery /dispatch

Excellent, solar 4mm² cable locked, no exposed wire, entire cable fits in connector, quick release
Excellent connectors. 6mm² cable compatibility means that the solar 4mm² cable I have easily fits with no exposed wires because the entire cable easily fits in to the connector. Simple flip of the switch and the cable is securely held in place. Pull test and the cable stays firmly locked.

WAGO 221-413 Compact Splicing Connectors
I’ve been using the WAGO 221-413 Compact Splicing Connectors and they’ve become my go-to solution for quick, secure, and reusable wire connections. These 3-conductor connectors are incredibly easy to use, thanks to the intuitive lever mechanism. No tools needed—just lift the lever, insert the wire, and close it. That’s it. The transparent housing is a thoughtful touch—it allows you to visually confirm a solid connection every time. They handle all conductor types (solid, stranded, and fine-stranded), up to 4 mm², and they’re rated up to 85°C, making them versatile and reliable even in more demanding environments. I’ve used them in lighting circuits, outlet splices, and temporary setups during renovations, and not once have they failed or loosened. The 50-piece pack offers great value for money, especially if you’re doing a lot of wiring work. These connectors also make future changes and maintenance much easier—just open the levers and reuse without damaging the wires or connector. Pros: • Very easy to use, no tools required • Accepts all conductor types up to 4 mm² • Reusable and reliable • Transparent housing for visual inspection • Compact design for tight spaces • Safe temperature rating (T85) Cons: • Slightly bulkier than traditional terminal blocks—but the convenience outweighs that If you’re an electrician, DIYer, or anyone doing any amount of wiring, the WAGO 221-413 connectors are a game-changer. They’re fast, safe, and make for incredibly neat work. Highly recommended.

I recently purchased Wago wire nuts for an electrical project, and I can’t recommend them enough! While they’re slightly pricier than traditional twist wire nuts, the ease of use and time savings make them worth every single penny. The lever-lock design is a game-changer—stripped wires slide in effortlessly, and a quick flip of the lever secures the connection tightly. No more wrestling with twisting or taping! I was able to complete my wiring tasks in half the time, and the clear housing lets you visually confirm the connection is solid. They’re also reusable, which is a huge plus for future adjustments. The build quality is top-notch, and they feel incredibly reliable for both home and professional use. If you’re looking for a faster, safer, and more convenient way to make wire connections, Wago wire nuts are absolutely the way to go. Worth the investment!

2020/01 He podido otra caja de estas clemas de 3 conexiones 221-413, y vuelvo a ver que vienen 51 piezas en lugar de 50 (adjunto foto con las piezas ordenadas en 5 grupos de 10 más una suelta). Así que muy bien 😏 Y siguen siendo las originales. Ya no me planteo trabajar con los sistemas antiguos de clemas o bornes de tornillos 🤦♂️ 2018/01 A pesar de que las fotos en Amazon vienen con letras chinas (y que leí algún comentario diciendo que podían ser imitación), aparentemente estos conectores son originales de Wago (y la caja también parece original). En la caja vienen 50 unidades (de hecho en la mía venían 51, o sea uno de más, así que perfecto). Son más pequeños que la serie a la que suceden (los 222), facilísimos de usar, muy robustos y agarran/pinzan el cable con muchísima fuerza: no hay manera de sacarlo estirando con dos manos una vez que la palanca está echada. Si la vuelves a levantar liberas el cable de nuevo, por lo que se pueden reutilizar varias veces (no sé si perderá algo de 'fuerza' por ello, pero no creo), o cambiar cables de un lado a otro o reconectarlos en cuestión de un segundo. Se agradece que sean transparentes (así te queda claro que el cable llegó hasta el fondo y que está correcto todo). Además como todos los hilos quedan dentro, protegidos, no hay ningún peligro de que al meter la mano en la caja de registro algún hilo suelto te de corriente (como ocurre con la parte trasera de las clemas/bornas antiguas de tornillos de toda la vida). Hay un abismo entre la rapidez de usar estos conectores y los de toda la vida de tornillos: ya no quiero otros que no sean estos. Sólo tengo una duda técnica (debida, seguro, a mi falta de conocimientos técnicos precisos): en un lado de cada pieza pone "JET 20 A 300V" y en el otro lateral pone "450V/32 A" (además de otras indicaciones que creo que se refieren al grosor del cable a usar). No sé por tanto si aguantan "sólo" 20 A o si aguantan 32 A (esto la caja tampoco lo aclara). No obstante parecen certificados para usar en instalaciones de cable de hasta 4mm según pone en los datos técnicos de la caja, etc. Lo único 'malo' es que te puedes pellizcar al bajar la palanca pero eso con un mínimo de cuidado lo evitas.

Todo bien , viene empacado y sellado. Es hasta para cables calibre 12 awg. Para calibre 10 hay otro modelo.
