Overview
The Eaton Cutler-Hammer 10250T1E logic contact block is a heavy-duty auxiliary contact module designed for integration with Eaton 10250T series 30.5mm pushbutton switches. This logic-level contact block features a 1NO/1NC (one normally open, one normally closed) contact configuration rated for 0.5A at 120VAC/VDC. With palladium contacts and a thermoplastic housing, the 10250T1E is engineered for dependable operation in automation and logic control applications across industrial environments.
Key Features
- 1NO/1NC Contact Configuration: Provides both normally open and normally closed contact pairs for flexible logic control
- Pressure Terminal Connections: Eliminates need for tools, enabling fast, secure terminal block connections
- Palladium Contact Material: Ensures reliable electrical conductivity and long operational life in automation equipment
- Stackable Design: Up to 6 blocks can be stacked for expanded circuit functionality (up to 12 circuits)
- NEMA Rated Enclosure Compatibility: Suitable for NEMA 3/3R/4/4X/12/13 and IP65-rated enclosures
- UL Listed and CSA Certified: Meets industry safety and performance standards

Compatibility & Replacements
The 10250T1E logic contact block is specifically designed for use with Eaton 10250T series 30.5mm pushbuttons and indicating lights. It is differentiated from the standard 10250T1 contact block (which has a higher 6A/10A rating and 600VDC specification) by its logic-level 0.5A/120VAC design. The /D2 variant designates specific environmental and operational parameters. For exact replacement compatibility or higher-current requirements, consult your application specifications or contact technical support. The pressure terminal connection makes installation straightforward in retrofit or new applications.
