Allen-Bradley 800T-B2A NSNBC01 Terminal Block

Allen-Bradley 800T-B2A NSNBC01 Terminal Block is a 30 mm, extended-head momentary push button from Rockwell Automation’s 800T family, designed for rugged industrial control panels. It carries a standard 1 NO, 1 NC contact block (compatible with 800T-XA) and features a black actuator with an extended head for easy actuation in tight spaces. The unit uses no guards on the terminals and is intended for 30 mm operator frame installation, enabling compact, modular control stations. In practical use, this configuration provides both a normally open and normally closed path in a single device, suitable for simple start/stop circuits and signaling within automated equipment. As a member of the 800T line, it can be combined with other 800T contact blocks and accessories to tailor a control station to specific machine requirements, while maintaining standard mounting and electrical compatibility across the family.
