Eaton 10250TK4 – Frequently Asked Questions

1) Will the Eaton 10250TK4 dust seal fit my 22mm pushbutton station?
No. The 10250TK4 is a 30.5mm heavy-duty dust tape seal, so it is sized for 30.5mm heavy-duty pushbutton and contact block assemblies only. A 22mm compact operator takes a different seal. Check the mounting hole size on the panel before ordering: 30.5mm is the heavy-duty industrial standard, 22mm is the metric compact size.
2) What contact blocks does the Eaton 10250TK4 seal work with?
It is made for Eaton B1 series contact blocks within the 10250T heavy-duty pushbutton line. If your panel uses B1 blocks behind 30.5mm operators, this is the matching dust tape seal. It is not a seal for the operator face or the panel gasket, it protects the contact block internals from dust and debris.
3) How much space does the Eaton dust tape seal add behind the panel?
Very little. The seal measures 4 x 5 x .3 inches, with the .3 inch dimension being its height, so it sits thin against the contact block housing and won't crowd a tight enclosure or stacked block assembly.
4) Is the Eaton 10250T dust seal UL Listed for use in a control panel?
Yes, it is UL Listed and CE Marked, which covers the usual spec requirements for industrial and machine control panel builds where listed components are called out on the drawing.
5) What part number do I order for the Eaton 30.5mm contact block dust seal?
Order Eaton MPN 10250TK4. That is the heavy-duty 30.5mm dust tape seal for B1 series contact blocks in the 10250T line, and it is sold as a single model with no finish or size options to specify.
6) Should I add dust seals to pushbuttons in a dusty plant, or is the enclosure enough?
An enclosure keeps bulk debris out, but grinding dust and airborne fines still reach contact block internals through the operator opening every time the panel is opened or a button is worked. The 10250TK4 tape seal closes that path at the block itself, which is why it shows up on machine control and operator interface stations in debris-prone areas. It is a low-cost consumable to add during scheduled maintenance on 30.5mm heavy-duty stations.
