Provides momentary 1NO/1NC switching for 16 mm push buttons at 6 A / 250 V AC
This 16 mm contact block is designed for use with Schneider Electric 16 mm push-button operators. It provides a single normally open and normally closed contact pair for momentary, break-before-make switching in industrial control panels. The unit is rated for 6 A at 250 V AC and carries NEMA B300/R300 designations. It suits panel builders and maintenance engineers assembling or repairing operator stations.
The decisive specification is the 1NO/1NC contact form rated at 6 A, 250 V AC with NEMA B300/R300 ratings. This defines the switching capacity and circuit logic the block delivers. Terminal connections accept slip-on, Faston or quick-connect terminals for straightforward wiring. Compliance includes CSA C22.2 No. 14, IEC 60947-1, IEC 60947-5-1, IEC 60947-5-5, JIS C4520, JIS C852 and UL 508. It is not suited for applications requiring higher current ratings or different contact configurations.
The block mounts directly to Schneider 16 mm push-button operators, so it cannot be used with 22 mm or other cut-out sizes. No additional hardware, software or wiring accessories are bundled; the part ships as a single contact block. Installers must supply compatible operators, enclosures and wiring terminals separately. It does not address needs for illuminated operators, selector switches or multi-contact assemblies.

It means the contacts can switch up to 6 amps at 250 volts AC in momentary or break-before-make action, within the B300/R300 NEMA designation limits.
The slip-on faston terminals accept standard quick-connect crimp terminals; the block is certified to CSA C22.2 No. 14, IEC 60947-1, IEC 60947-5-1, IEC 60947-5-5, JIS C4520, JIS C852 and UL 508.
The block snaps onto any Schneider 16 mm push-button operator; no separate screws or brackets are required for the contact block itself.
