Through terminal block, 2250 Series, orange Our through terminal block (item number 2250-322) is the perfect way to connect conductors quickly and easily. Conductors can only be connected to this through terminal block if their strip length is between 9 and 11 mm . Whether for use in industry or building installations, our rail-mount through terminal blocks make it easy to quickly and securely connect electrical conductors. They’re perfect for either classic through-wiring or distributing potential, depending on the variant. Featuring conductor terminals along with Push-in CAGE CLAMP®, this connector outperforms the competition. Push-in CAGE CLAMP® connection technology is ideal for connecting all conductor types. It allows direct insertion of both solid and fine-stranded conductors with ferrules without needing to use any tools—all thanks to its pluggable design. This through terminal block is suitable for conductor cross sections ranging from 0.14 mm² to 1.5 mm². A push-button is used to operate this mini rail-mount terminal block. Our TOPJOB® S rail-mount terminal blocks offer more than just secure electrical connections in a range of different industrial applications and modern building installations. They also offer the perfect actuation variant for every use: lever, push-button, or operating slot. This product is designed for specific Ex applications (please refer to the product datasheet).
