B-LINE 10250T4033 – Frequently Asked Questions
1) What panel hole size does the B-Line 10250T4033 selector switch operator need?
It mounts in a standard 30.5 mm panel hole, which is the heavy-duty push button and selector switch standard used across the 10250T series. If your enclosure is drilled for 22 mm operators, this one will not drop in without an adapter or a redrilled opening.
2) Can the B-Line 10250T4033 selector switch be used in a washdown or outdoor enclosure?
It carries NEMA 3, 3R, 4, 4X, 12 and 13 ratings, so it holds up in rain-exposed outdoor panels, hosedown and washdown areas, and dust or oil-laden industrial spaces. The 4X rating is the one that covers corrosive environments like food processing and wastewater. The enclosure itself has to carry the matching rating for the assembly to hold it.
3) Does the 10250T4033 include contact blocks, or do I order those separately?
This is the operator only, the 30.5 mm three-position selector head itself. Contact blocks, legend plates and any mounting latch are ordered as separate 10250T series parts. Match the contact block arrangement to Cam 3, which is the switching cam this operator uses.
4) I am replacing a selector switch in an existing 10250T panel. Will the 10250T4033 drop in?
It will fit the same 30.5 mm opening as any other 10250T heavy-duty operator. What you need to match is the function: three positions, 60 degree throw, non-illuminated, Cam 3. A two-position or maintained/spring-return variant with a different cam will look identical in the hole but switch differently.
5) Is the 10250T4033 selector switch illuminated?
No. It is a non-illuminated operator, so there is no lamp, no transformer and no lamp voltage to specify. If you need position indication at the door, use a separate 30.5 mm indicating light rather than expecting it from this knob.
6) What does the Cam 3 code on the 10250T4033 selector switch mean for my contact wiring?
The cam code sets which contacts make and break at each of the three positions. The 10250T4033 uses Cam 3, so when you spec contact blocks for it, the circuit sequence follows that cam pattern. If a panel drawing calls out a different cam, the operator is the wrong one, not the contact block.
7) What is the exact part number to order this B-Line heavy-duty selector switch operator?
Order it as B-Line 10250T4033. That single part number covers the 30.5 mm heavy-duty three-position non-illuminated selector switch operator with Cam 3 and a 60 degree throw.
