Through terminal block, 2252 Series, push-button Our through terminal block (item number 2252-1205) is designed for seamless electrical installations. Strip lengths must be between 10 and 12 mm when connecting conductors to this through terminal block. Our mini rail-mount terminal blocks are perfect for working in tight spaces thanks to their compact design. With various mounting and actuation options, they offer maximum flexibility. This product features conductor terminals and utilizes Push-in CAGE CLAMP®. Our Push-in CAGE CLAMP® is a universal, maintenance-free connection solution for all conductor types, featuring a winning design: It allows direct insertion of both solid and fine-stranded conductors with ferrules without needing tools. No preparation is required; for example, crimping the conductor's ferrule is not necessary. This through terminal block is suitable for conductor cross sections ranging from 0.25 mm² to 4 mm². This mini rail-mount terminal block is operated with a push-button. Our TOPJOB® S rail-mount terminal blocks offer more than just secure electrical connections in various industrial applications and modern building installations. They also offer the perfect solution for every use: lever, push-button, or operating slot. This product is designed for specific Ex applications (please refer to the product datasheet).
