Overview
The Eaton Cutler-Hammer 10250T1323 is a heavy-duty selector switch operator from the 10250T series. It is a 3-position 60° Throw Maintained Vertical Mounting Selector Switch with black knob. This selector switch operator features a three-position knob actuator with black color, Cam 3 configuration, and 60 degree throw for maintained action in demanding environments. The switch is designed for rugged industrial use with zinc die-cast construction and chrome plating for corrosion resistance.
Key Features
- Heavy-Duty Construction: Features a heavy-duty zinc die cast construction
- Reliability Enhancement: Reliability nibs improve contact reliability even under dry circuit and fine dust conditions, with enclosed silver contacts featuring pointed reliability nibs
- Environmental Protection: Drainage holes prevent the build-up of liquid inside the operator, which can prevent operation in freezing environments
- Maintained Action: All three positions stay-put; ideal for maintenance selector functions where operator choice must remain locked
- Standard Mounting: 30.5mm round mounting with standard knob handle for easy operation
