Bulletin 280 ArmorStart

The Allen-Bradley Bulletin 280 ArmorStart accessories family covers the power-connection hardware — receptacles, reducing adapters, and power tees — used to wire and configure ArmorStart distributed motor controllers in the field. The catalog numbers follow a consistent structure: the 280 prefix is always present, the next segment identifies the connector body style and thread size (e.g., M22 or M35, indicating 22 mm and 35 mm power connector formats), the following character indicates gender (F = female socket, M = male plug), and an optional suffix denotes wire gauge and phase count for pre-terminated flying-lead versions. Popular in-stock examples include the 280-FAM29F and 280-FAM29M field-attachable receptacles (wires not included), the 280-M35F-M1 female receptacle with pre-attached 10 AWG three-phase leads, and the 280-M22M-M1 male receptacle with 16 AWG flying leads. The 280-RT35 power tee reducing drop adapts M35 to M22 connections, while the 280-RA35 reducing adapter accommodates standard ArmorStart mounting threads. Consult the Bulletin 889/880 Connectivity Technical Data (889-TD002) for full wiring and environmental ratings across the family.
