Building Installations: Splicing Connectors or Pluggable Connectors?

Classic installation with splicing connectors or pluggable with WINSTA®? No matter which type of electrical installation you prefer, WAGO offers the right products for connection technology — and supports you in meeting evolving challenges.

Which Wiring Type Is Right for Me?


A customer calls, and you need to connect conductors of different types and sizes quickly and flexibly? Planning minor repairs, maintenance, or renovations? Then classic splicing connectors — such as those in the 221 Series — are the perfect choice!

Working on a larger project? Planning the electrical installation of modular buildings, facilities that are frequently modified or expanded, or applications where standardization and repeatability are essential? Short on time at the construction site and prefer a preplanned electrical installation that only needs to be plugged together on-site? Choose a customized, pre-assembled installation with WINSTA® pluggable connectors!

Building Installation

Conventional or Pluggable Installation

Classic or pluggable electrical installation? Below you’ll find additional information on wiring options using WAGO Splicing Connectors or WINSTA® Connectors.

Conventional Wiring

We offer spring pressure connection technology for electrical installations — from junction boxes and PCBs on up to control cabinets. Simple, secure, and maintenance-free operation is what makes our connection technology stand out. Thanks to their compact design, our connectors save space and are intuitive — for example, with the 221 Series, solid conductors can be inserted directly, and lever technology simplifies handling.

Pluggable Electrical Installations

Fast, pluggable, and error-free — that’s how electrical installation should work. With WINSTA®, we offer the ideal pluggable connection system to meet your building installation requirements. For every application, we provide the right version of plugs and sockets, snap-in device connectors, PCB connectors, distribution connectors, cable assemblies, and distribution boxes.
