Description

PCB terminal block, 250 Series, greenOur PCB terminal block (item number 250-704/000-023) is designed for seamless electrical installations. It is ideal for custom installations with different mounting types. This PCB terminal block has a rated voltage of 320 V and can handle currents up to 10 A. Conductors should only be connected to this PCB terminal block if their strip length is between 9 mm and 10 mm. This product features one conductor terminal and utilizes Push-in CAGE CLAMP®. Push-in CAGE CLAMP® technology provides a universal connection solution for any type of conductor. It allows both solid and fine-stranded conductors with ferrules to be inserted directly into the clamping point without the need for tools. The item’s dimensions are 21.2 x 24.9 x 21.7 mm (width x height x depth). Depending on the type of conductor, this PCB terminal block is ideal for conductor cross sections ranging from 0.5 mm² to 1.5 mm². Up to eight potentials / eight poles can be connected to this terminal strip using eight clamping points on two levels. The clamping spring is made of chrome-nickel spring steel (CrNi), the green housing is made of polyamide (PA66) for insulation, and the contacts are made of electrolytic copper (ECu). The contact surface is coated with tin. This PCB terminal block is operated with a push-button. THT is used to solder the PCB terminal block. Insert the conductor into the board at a 45° angle.. The solder pins are organized over the entire terminal strip (in-line) and are 0.5 x 0.75 mm and 4 mm in length. Each potential has one solder pin.
