B-LINE 10250T16777H634 – Frequently Asked Questions
1) Is this selector switch rated for a washdown or outdoor enclosure?
It carries NEMA 3, 3R, 4, 4X, 12 and 13 ratings, which covers rain and sleet outdoors, hosedown and washdown areas, corrosive environments (4X), and dust or oil-laden industrial spaces. The overall protection you get still depends on the enclosure it is mounted in matching that rating.
2) How many positions does the B-Line 10250T16777H634 selector switch have, and how far does it rotate?
Four positions, with 40 degrees of throw between them. That geometry suits mode selection on a machine (for example off, hand, auto, plus a fourth state) rather than a simple two-position on/off duty.
3) Is this a knob selector switch or a key-operated one?
Key-operated. The actuator is a key, not a knob or lever, so only someone holding the key can change position. That is the version to specify when you need to lock out a mode change on a machine or restrict who can put a system into auto or manual.
4) What key code does this B-Line selector switch use, and can I key several panels alike?
The key code is H634. Any other 10250T key selector ordered with the same H634 code will operate with the same key, which is how you standardize one key across multiple panels or lines. A unit with a different code number will not accept it.
5) Does this switch light up to show the selected position?
No. The 10250T key selector switch is non-illuminated, so there is no built-in lamp or LED indicating position. If your operators need a visual state indication at the panel, plan on a separate pilot light in addition to this switch.
6) Is the B-Line 10250T16777H634 an assembled unit or do I have to order the operator and contact blocks separately?
It ships as an assembled selector switch, so the operator and its contact arrangement come together as one catalog number rather than as separate operator and block pieces you build up on the bench.
