Allen-Bradley 800H-NP40J Bulletin 800H Jumbo Protective Ring

Allen-Bradley 800H-NP40J is a stainless steel protective ring built for Bulletin 800H jumbo-size push-button assemblies, delivering a rugged guard around two-position non-illuminated push-pull operators (60 mm diameter) to help prevent unintentional actuation in demanding industrial environments. It is listed by Rockwell Automation as the Jumbo Protective Ring for the 800H family, carrying catalog number 800H-NP40J and specifically sized for the 60 mm jumbo button subset used with Type 7 & 9 protective hardware. The accessory is commonly described as a safety guard that, when used with 800H devices, helps avoid inadvertent trips of E-stop operators in hazardous locations, a use case documented in Rockwell's 800-TD011 technical data. When paired with Bulletin 800H components, the 800H-NP40J provides a durable stainless steel surround to the push-pull actuator, aligning with the official protective-ring offerings in the 800H accessory lineup and contributing to overall device safety without altering electrical functionality.
