B-LINE 10250TA77 – Frequently Asked Questions
1) Is the 10250TA77 a two-button start/stop unit, and can both be pressed at once?
It is a two-button mushroom head operator with one green and one red actuator, and they are mechanically interlocked. The interlock means pressing one releases or blocks the other, so you cannot hold both in at the same time. That is what you want for a start/stop or forward/reverse station where simultaneous commands must be prevented.
2) Does the B-Line 10250TA77 stay pressed in, or does it spring back?
It is a maintained operator. Press it and it stays in that position until the opposite button is pressed, which is what a motor start/stop station needs. If your application calls for a momentary jog button that springs back on release, this is the wrong operator.
3) Can the 10250TA77 pushbutton be used in a washdown or outdoor enclosure?
The operator carries NEMA 3, 3R, 4, 4X, 12 and 13 ratings, which covers outdoor rain and sleet exposure, hosedown and washdown, corrosive duty, and dust or oil in industrial plants. The enclosure it goes into has to carry the same rating for the assembly to hold it.
4) Does the 10250TA77 include contact blocks, or do I order those separately?
The 10250TA77 is the operator only, the mushroom head buttons and chrome bezel that mount to the panel. The 10250T contact blocks that make and break the circuit are ordered separately and stacked on the back of the operator, so specify the NO and NC block count your control scheme needs.
5) Are the buttons on the 10250TA77 lit?
No. It is a non-illuminated operator, so there is no lamp or LED behind the green and red mushroom heads. If the panel needs a lit button to show run status, use an illuminated 10250T operator or add a separate 30.5 mm pilot light.
6) Are the mushroom buttons metal or plastic on the B-Line 10250TA77?
The actuators are plastic, set behind a chrome bezel. Plastic heads are non-conductive and hold color better in washdown areas; if the station takes heavy physical abuse and you want metal heads, look at a metal-actuator 10250T operator instead.
7) What is the part number to reorder this B-Line interlocked start/stop operator?
Order it as B-Line 10250TA77, part of the 10250T heavy-duty 30.5 mm line. That number gets you the interlocked green and red mushroom head maintained operator with the chrome bezel.
