Allen-Bradley 609-BOW21 Manual Starting Switch

Allen-Bradley 609-BOW21 is a three-phase manual starting switch with a push-button control, provided as an open-type NEMA 1 device without an enclosure. It’s designed for motor-starter installations where remote push-button control is not required, enabling local operation in a 3‑phase circuit. The unit is rated for a maximum of 600 V and is part of Rockwell Automation’s Bulletin 609 family of manual starting switches, catalog item 609-BOW. This model represents the 3‑phase variant of the 609‑BOW line and is commonly used in industrial control panels or equipment that require a straightforward, locally actuated start function without enclosure hardware. The open-type design means the switch is supplied without a mounted enclosure, allowing installers to mount it within an existing control cabinet or on a suitable support where a manual start is needed. Related variants in the Bulletin 609 family, such as 609-AOW21 and 609-BAW21, cover other configurations while preserving the same basic manual-starting functionality for 3‑phase motors.
