194L-HE8N-175

Overview of Allen Bradley 194L-HE8N-175

The Allen Bradley 194L-HE8N-175 is an actuator handle designed for use with 194E series control and load switches, providing manual operation and lockout capabilities for industrial disconnect applications. This Size 8 actuator features a distinctive red and yellow disc-type control knob that facilitates safe operation and clear visual status indication. The handle supports 0-1 and OFF-ON switching positions with a 90-degree rotation, enabling straightforward control of electrical loads. Built for demanding industrial environments, the 194L-HE8N-175 includes provisions for up to three padlocks, allowing multiple authorized personnel to implement lockout/tagout procedures simultaneously. The 90mm x 90mm mounting footprint ensures compatibility with standard panel cutouts and provides a secure, stable installation. This actuator is specifically engineered for 194E switches rated from 40A to 100A, making it suitable for motor control centers, machine panels, and distribution equipment where reliable manual disconnect operation is required.

Applications / Use Case

The Allen Bradley 194L-HE8N-175 actuator serves critical roles in industrial safety and control applications where manual disconnect operation is necessary. It is commonly deployed in motor control centers to provide operators with direct control over motor starters and feeder circuits, enabling safe equipment shutdown during maintenance procedures. Manufacturing facilities use this actuator on machine panels and production equipment where lockout/tagout compliance is mandatory, with the three-padlock provision supporting group lockout scenarios involving multiple maintenance technicians. Distribution panels and switchgear applications benefit from the clear visual indication provided by the red/yellow color scheme, reducing the risk of accidental energization. The IP65 rating makes this actuator suitable for harsh industrial environments including food processing, automotive assembly, and chemical processing facilities where exposure to dust, moisture, and washdown conditions is common. The 90-degree rotation provides positive engagement and clear position feedback, while the disc-type knob design allows for easy operation even when wearing work gloves.
