B-LINE E34EX7003 – Frequently Asked Questions
1) Can I use the B-Line E34EX7003 control station in a Class I Division 2 hazardous area?
Yes. The E34EX7003 assembled control station is rated for NEC Class I Division 2, Groups B, C and D, and it also carries NEMA 4, 4X, 12 and 13 enclosure ratings. That combination covers wet, washdown, dust and oil environments as well as Division 2 gas atmospheres, so it suits gas processing, fuel handling, and chemical plant control points.
2) What does the E34EX7003 do when you press it, and does it stay in?
It is a momentary flush pushbutton legended START, so contacts transfer only while you hold it and return as soon as you release. If your circuit needs a button that stays latched (for example a maintained stop or selector function), this is not the right unit.
3) How many contacts does the B-Line E34EX7003 come with?
One element with a 1NO-1NC contact block. The normally open contact handles the motor starter or PLC start input while the normally closed contact is free for an interlock, indication, or a second circuit. There is one operator in the station, not a multi-button assembly.
4) Will the E34EX7003 accept standard 30.5 mm pushbutton operators if I need to swap one later?
It is a 30.5 mm device, the standard heavy duty panel hole size, so replacement operators and contact blocks in that size line up with the enclosure prep. B-Line notes that where the station is exposed to ultraviolet light you should use NEMA 4X 10250T operators.
5) Is the E34EX7003 enclosure suitable for outdoor mounting in direct sun?
The die cast enclosure is NEMA 4X rated, so outdoor and washdown mounting is fine from a water and corrosion standpoint. For sunlit locations, B-Line specifies using NEMA 4X 10250T operators, since UV exposure is the limiting factor rather than the enclosure itself.
6) Do I have to assemble and wire the operator into the E34EX7003 box myself?
No. It ships as an assembled control station, meaning the green flush START pushbutton and its 1NO-1NC contact block are already installed in the die cast enclosure. You mount it, run conduit, and terminate to the contacts.
7) Is the green flush button on this B-Line station a good choice for an emergency stop?
No. A green flush momentary button legended START is the industry convention for a run or start command, not a stop. Emergency stop calls for a red mushroom head maintained or push-pull operator. Order the E34 station configured that way instead of using this one.
8) What is the exact part number and series for this B-Line control station?
Manufacturer part number E34EX7003, from the B-Line E34 series of 30.5 mm Class I Division 2 control stations. Quote that number when matching existing stations on a site so you get the same green START flush button and 1NO-1NC element.
