Connection method offers new applications for compact power PCB terminals

Wago offers six new PCB terminal blocks to allow equipment designers and OEMS to free up space or use smaller PCBs and enclosures. Push-in connection reduces installation time, while a spring pressure mechanism protects wiring against vibration and temperature cycling, improving reliability. The terminal blocks are rated for 4mm2, 6mm2 and 16mm2 conductors, and can connect most solid and fine-stranded conductors up to the next larger cross-section size from their rated cross-section, saving space on the PCB. A rated voltage of up to 1000V and 76A makes the terminal blocks ideal for demanding applications such as power supplies, frequency inverters or servo drives. The increasingly compact design of these devices for industries such as energy means that components must be more densely populated on the PCB while still retaining a high power rating. The small footprint of the company’s new variants helps to address this problem, making them suitable for use in space-restricted and panel feedthrough applications.
