Overview
The Eaton 10250T172 is a non-illuminated momentary pushbutton operator with a jumbo mushroom head, designed for heavy-duty industrial automation and emergency stop applications. This 30.5 mm device provides NEMA 3, 3R, 4, 4X, 12, and 13 enclosure ratings with a red actuator, chrome bezel, and anodized aluminum construction. The 10250T172 integrates seamlessly into standard 10250T series control systems and HMI panels.
Key Features
- Zinc die cast construction with chrome-plated housing and mounting nut
- Reliability nibs improve contact reliability even under dry circuit and fine dust conditions
- Drainage holes prevent liquid build-up inside the operator, preventing operation failure in freezing environments
- Non-illuminated red mushroom operator for emergency stop/emergency control signaling
- Grounding nibs enhance ground connection when the device is securely tightened
- Momentary action with screw terminal contact block
