What is the Wago 285-143?
High-current terminal block, 285 Series, light gray
Our through terminal block (item number 285-143) ensures effortless electrical installations. Ensure that the strip lengths are 32 mm when connecting conductors to this through terminal block. This product incorporates conductor terminals and utilizes POWER CAGE CLAMP. The POWER CAGE CLAMP is perfect for connecting large conductor cross-sections. This universal connector is both reliable and maintenance-free. What’s more, you can use it to connect all types of conductors and the clamping point can be locked open, making it easier to use. You do not need to use a torque wrench or prepare the conductor. For example, crimping ferrules is not necessary. Depending on the type of conductor, this through terminal block is designed for conductor cross sections ranging from 10 mm² to 50 mm².
This product is designed for specific Ex applications (please refer to the product datasheet).
