Eaton 30 mm contact block

The Eaton Cutler-Hammer 10250T51 is a single normally-closed contact block rated at 10 A and 660 V AC/DC. It is designed for 30 mm push-button operators and indicating lights in industrial control panels. The grey housing uses pressure-terminal connections for secure wiring.

Suited for 10250T panel builds

This block suits installers expanding or maintaining Eaton 10250T 30 mm operator stations who need a momentary 1NC function. It carries CE, CSA and UL listings with NEMA A600/P600 ratings. Buyers requiring normally-open contacts, different voltage ratings or alternative mounting footprints should look at other blocks.

Pressure terminals simplify wiring

The supplied pressure terminals accept stripped conductors directly, removing the need for separate lugs or ferrules. This reduces assembly time and ensures a reliable connection in vibration-prone cabinets. No additional accessories or software are included with the block.

Questions about this item

Which 30mm Eaton 10250T push buttons or indicating lights does this 10250T51 contact block mount to?

It fits any Eaton 10250T series 30mm operator — push buttons, selector switches or pilot lights — that accepts a snap‑on contact block.

Can I keep my existing A600/P600 rated control wiring when adding this 1NC block?

Yes, the block carries the same NEMA A600/P600 rating and 10A at 660V AC/DC, so your current wiring remains valid.

How do I verify the normally‑closed contact opens cleanly when the operator is pressed?

With power off, measure continuity across the pressure terminals; the meter should show open circuit while the button is held and closed when released.
