Eaton 10250TER – Frequently Asked Questions

1) Will the Eaton 10250T illuminated knob fit a standard 30.5 mm panel cutout?
Yes. The 10250TE knob is a 30.5 mm heavy-duty actuator, so it drops into the standard 30.5 mm operator hole used across Eaton's heavy-duty pushbutton and switch line. If your panel is punched for 22 mm devices, this is the wrong size family.
2) What Eaton switch does the 10250TE knob actually mount on?
It is the actuator for illuminated selector switches in the Eaton 10250T heavy-duty operator series. It is not a pushbutton cap and not a non-illuminated selector knob, so the switch body underneath has to be the illuminated selector type.
3) Does this knob come with position markings like OFF-ON or HAND-OFF-AUTO?
No. This is the blank legend configuration, with no positions printed on it. If you need the positions marked, either use a legend plate around the operator or label it yourself. Other legend options exist elsewhere in the 10250T family.
4) I'm replacing a cracked knob on an existing Eaton panel station. Do I have to swap the whole switch?
No. The knob is sold as a standalone actuator for the 10250T heavy-duty operator platform, so on an illuminated selector switch you can replace just the knob and leave the switch body, contact blocks, and wiring in place. Confirm the existing operator is an illuminated selector and 30.5 mm before ordering.
5) Which colors does the Eaton 10250TE illuminated selector knob come in, and what are the part numbers?
Five lens colors: clear (10250TEC), green (10250TEG), blue (10250TEL), red (10250TER), and white (10250TEW). Since the knob lights up, color choice drives what the operator signals on the panel, so match it to your existing color convention for run, stop, and standby positions.
6) Can this knob hold up in a washdown area or a machine that leaks cutting oil?
The 10250T knob is built as a sealed watertight/oiltight actuator, which is what you want on plant-floor stations exposed to hose-down cleaning or oil mist. Sealing at the panel face also depends on the switch body and gasket behind it being the matching watertight/oiltight unit.
7) Is the Eaton 10250TE knob CE marked for a machine going to Europe?
CE Marked, yes, which is the compliance this operator carries for regulated installations. That is the only marking stated for the part, so if your spec calls out additional third-party listings, verify them against the switch body you are pairing it with.
8) Does buying this knob include the lamp or the contact blocks?
The knob is the actuator only. The illuminated selector switch body, its lamp or LED, and the contact blocks are separate 10250T components you order to suit the circuit. Plan the order as operator plus knob, not knob alone, on a new panel build.
