Description
PCB terminal block, 255 Series, with 7.5 mm pin spacingQuick and easy connections are guaranteed with this PCB terminal block (item number 255-502/333-009). You can rely on trusted safety with these PCB terminal blocks, perfect for a wide range of applications when designing your devices. Rated current and voltage are important parameters when selecting a PCB terminal block, as they determine the product’s suitability for different applications. This product has a rated voltage of 630 V and a rated current of 24 A, making it suitable for high-load applications. Conductors should only be connected to this PCB terminal block if their strip length is between 5 mm and 6 mm. This product features one conductor terminal and utilizes CAGE CLAMP®. Our renowned universal connection known as CAGE CLAMP® leads the way when it comes to connection technology and electrical interconnections. The item’s dimensions are 17.9 x 22.2 x 23 mm (width x height x depth). Depending on the conductor type, this PCB terminal block is ideal for conductor cross sections ranging from 0.08 mm² to 2.5 mm². It has one level. Two potentials can connect two poles using the two clamping points The clamping spring is made of chrome-nickel spring steel (CrNi), the light gray housing is made of polyamide (PA66) for insulation, and the contacts are made of electrolytic copper (ECu). Tin is used for coating the contact surfaces. Finger-operated lever is used to operate this PCB terminal block. The PCB terminal block is designed for THT soldering. Insert the conductor at an angle of 90°.. The solder pins, which are 0.7 x 0.7 mm in cross-section and 4 mm long, are arranged over the entire terminal strip (in-line). There are two solder pins per potential.
