Allen-Bradley 194R-HM4-L Long Operating Handle is a heavy-duty actuator accessory for 194R disconnect switches rated 600–1250 A, designed to provide a longer reach for reliable, hands-on operation in demanding installations. The HM4-L variant features a black handle with a light-gray cover and is designed for standard orientation with a built-in defeater, enabling secure lockout/tagout during maintenance. This long operating handle carries IP65 ingress protection and is compatible with NEMA Type 1, 3R, 12, 4, and 4X environments, making it suitable for wet, dusty, and harsh industrial settings. It accepts up to three padlocks to facilitate multi-point locking during LO/TO procedures. Specifically specified for 194R disconnect switches in the 600–1250 A range, the HM4-L enables safe, deliberate manual isolation in control panels, switchgear, and other heavy-duty electrical equipment.
