The screwless SNK Series PI-Spring Terminal Block from ABB Low Voltage Products division features a patented spring design that enables the installer to lock a screwdriver onto a terminal connected to unprepared flexible conductors. This is designed to free the installer's hands to manipulate wires and hold circuit drawings.
SNK Series PI-Spring Terminal Blocks combine push-in and spring technologies for efficient connections to solid and stranded wires, either with or without ferrules.
"The new PI-Spring enhances our existing SNK series screw-clamp range and applies the best of 50 years of experience to one easy-to-connect, high-quality product, with common accessories," said Frederic Stuckelberger, ABB Global Product Group Connection Manager. "These terminal blocks are designed for medium and heavy industrial applications, including marine and hazardous locations, as well as solar power and commercial building applications."
The SNK Series PI-Spring Terminal Blocks feature self-guiding wire entries that enable direct, one-step, push-in insertions with solid wires and stranded wires with ferrules. PI-Spring Terminal Blocks also enable stranded wire to be inserted with a screwdriver to open the spring clamp. Reducing connection time for push-in mode and eliminating the need to prepare stranded wires for spring mode make installation quick and easy for both methods.
"Another advantage of the SNK Series PI-Spring Terminal Blocks' combined push-in and spring technology is the reduction of inventory by up to 50 percent, as they eliminate the need to stock a separate line for solid and ferruled stranded wires, and another separate line for unprepared stranded wires," said a company spokesperson. "Additionally, SNK Series PI-Spring and Screw terminal blocks share the same jumpers, markers and accessories, while all end section and circuit separators fit multiple types and sizes of blocks."
The wire entry angle of the SNK Series PI-Spring Terminal Blocks is designed to minimize the height of the wires while maintaining a generous bend radius, which increases the integrity of the connection and decreases the space that the wires occupy for a narrower wireway in the enclosure. The asymmetrical design of the SNK Series PI-Spring Terminal Blocks provides an immediate visual check to ensure against terminal block reversal, which reduces the chance of mounting and wiring errors. "Circuit identification is also improved with a 20 percent enlargement of the marking area. The 30° angle of the wire entry on the terminal block's profile provides up to a 15 percent increase in rail and cabinet space, while allowing a generous bend radius. The flat marking surface enables pre-marking by hand before final marker installation," said the spokesperson.
ABB's SNK Series PI-Spring Terminal Blocks are available from stock at authorized ABB distributors.
