B-Line 30.5 mm, Heavy-Duty Roto-Push Operator

It mounts in a standard 30.5 mm panel hole, which is the common heavy-duty control station size for 10250T series devices. If your enclosure or control panel is punched for 22.5 mm pilot devices, this operator will not drop in without an adapter or a re-punch.

Yes. The 10250T2515 carries a NEMA 3, 3R, 4, 4X, 12 and 13 performance rating, so it is rated for dust, rain, hosedown, corrosion resistant (4X) and oil-tight industrial duty. That covers outdoor enclosures, food and beverage washdown areas, and machine tool panels exposed to coolant.

No. The 10250T2515 has a flush black actuator, and an emergency stop device needs a red mushroom head operator to meet the colour and shape convention crews and inspectors expect. Use this one for maintained control functions, and order a dedicated red mushroom E-stop operator for emergency stop duty.

A roto-push operator is pushed in to actuate and then rotated to release, so it stays latched until someone deliberately turns it back. Electricians use it where an operator must not be reset by a bump or a glove, for example a maintained stop or a hold function. If you want the contacts to change state only while the button is held, a standard momentary flush or extended button is the right part instead. The 10250T2515 has a flush actuator in black.

Cam 5. The cam is the profile behind the operator that decides how and when the attached contact blocks transfer as the button is pushed and rotated. It matters because the cam must match the contact sequence your control drawing calls for, so specify Cam 5 when confirming against a schematic or when replacing an existing operator.

The operator body measures 2.1 x 1.9 x 1.9 inches. Leave clearance for that footprint plus the depth of whatever contact blocks you stack on the back, and note it is built for horizontal mounting, so plan the enclosure layout and wire dress accordingly.

Yes, for panel appearance and hole size. As a 30.5 mm heavy-duty 10250T device it uses the same panel punch and the same family of contact blocks and legend plates as the rest of your 10250T stations, so it standardises cleanly across a plant. The difference to be aware of is the function: this is a roto-push with a flush black button and Cam 5, not a plain momentary.
