B-LINE 10250H4240 – Frequently Asked Questions
1) Can the B-Line 10250H4240 START/STOP station be used outdoors or in a washdown area?
The 10250H4240 control station carries NEMA 3, 3S, 4, 4X, 12 and 13 ratings, so it handles rain and windblown dust outdoors, hose-directed water in washdown bays, and oil or coolant spray on a plant floor. The 4X portion covers corrosive environments, which is consistent with the polyester enclosure rather than a painted steel box.
2) What contacts do I get with this two-button START/STOP station, and will it run a standard 3-wire motor starter circuit?
Contact configuration on the 10250H4240 is 1NO-2NC across its two operator elements. That gives you a normally open contact for the START button plus normally closed contacts for STOP, which is the arrangement a three-wire start/stop seal-in circuit around a motor starter coil needs. Legend is factory marked START/STOP, so no field labeling.
3) Do I need to cut a hole for this pushbutton station or does it mount on the wall as-is?
It is a surface-mount assembled station, so it bolts onto a wall, machine frame, or column with the operators already installed and wired to terminals inside. No panel cutout or 30.5 mm punching required. Plan for a box footprint of 10.6 by 6.5 by 6.4 inches and 3.8 lb of weight when you pick fasteners and anchors.
4) Does this station include an emergency stop mushroom head?
No. Both elements on the 10250H4240 are booted pushbuttons legended START/STOP. The stop is a standard flush booted button, not a maintained mushroom-head E-stop, so it does not satisfy an emergency-stop requirement. Order a dedicated E-stop station for that duty.
5) Are the buttons on the 10250H4240 sealed, and what do they look like?
Both operators are booted pushbuttons in black with a chrome bezel. The rubber boot over the button is what keeps water and dust out of the operator itself in a washdown or dusty area, and it also lets an operator work the station with a gloved hand.
6) Is the enclosure on this control station metal?
No. The housing is polyester, a nonmetallic material, which is why it carries the 4X corrosion rating. If your specification calls for a metallic enclosure, for grounding continuity through the box or for impact from moving equipment, this is not the station to use.
7) What part number do I order for a B-Line 30.5 mm start/stop station in a nonmetallic box?
Order MPN 10250H4240 from the 10250H heavy-duty line: an assembled two-element surface station, black booted buttons, chrome bezels, START/STOP legend, 1NO-2NC contacts, polyester enclosure rated NEMA 3, 3S, 4, 4X, 12 and 13.
