Information About 10250T20KB
The 10250T20KB is a selector switch from Eaton’s 10250T heavy-duty line designed for industrial operator control stations and equipment interfaces. Built around a 30.5 mm mounting format, it uses a black knob actuator to provide clear tactile switching between two defined positions. Its 1NO-1NC contact arrangement offers flexible control logic suitable for start/stop, enable/disable, or mode-selection functions. With NEMA 3, 3R, 4, 4X, 12, and 13 environmental ratings and a 60° throw mechanism, the switch ensures reliable manual operation in environments exposed to moisture, dust, oils, or corrosive conditions.
Key Features
- Heavy-Duty 30.5 mm Construction: Built for long-term durability in industrial control panels and operator stations using a robust mechanical housing.
- Two-Position Selector Function: Provides clear mechanical detents for defined switching states, supporting simple operational modes.
- 1NO-1NC Contact Arrangement: Offers flexible control logic for use in interlocks, machine functions, or multi-state equipment commands.
- Black Knob Actuator: Ensures comfortable grip and consistent operation across repetitive switching cycles.
- 60° Throw Operation: Delivers precise mechanical travel between selector positions, enhancing operator accuracy.
- Wide NEMA Environmental Protection: Rated for NEMA 3, 3R, 4, 4X, 12, and 13, enabling installation in wet, dusty, corrosive, or general industrial environments.
- Non-Illuminated Design: Suitable for applications where visual indication is not required or where dedicated pilot lights are used separately.
- Assembled Switch Package: Delivered with all necessary components for immediate installation into standard 30.5 mm control panel cutouts.
The 10250T20KB delivers the reliability and precision required for demanding industrial operator control applications.
