ABB SNK Series PI-Spring Terminal Blocks Enable Faster Connections

The new screwless SNK Series PI-Spring Terminal Block from ABB Low Voltage Products division features patented spring design that enables the installer to lock a screwdriver onto a terminal connected to unprepared flexible conductors. This innovation frees 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 that are 50 percent faster than terminal blocks with screw clamps. 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.
