B-LINE 57-2579A – Frequently Asked Questions
1) How much panel space does the B-Line 57-2579A pilot device take up behind the door?
Plan for roughly 2.5 in height, 1.88 in length and 1.84 in width on the B-Line 57-2579A. On a shallow enclosure door or a crowded control panel, that 1.88 in depth dimension is the one to check against your back-panel clearance before you cut the opening.
2) Is the B-Line 57-2579A a 22mm or a 30mm pilot device?
It is a 30mm device. If your existing panel cutouts were drilled for 22mm pilot devices, this one will not drop into them without enlarging the hole, so match the series to the cutout you already have.
3) What part number do I order for the B-Line Ashville IDT MJG39 30mm pilot device?
Order it as B-Line 57-2579A. That model number is the full ordering identity for the Ashville IDT MJG39 30mm pilot device, and it is the same number printed on the manufacturer spec sheet for the part.
4) Where can I get the full electrical specifications for the B-Line Ashville IDT MJG39?
The manufacturer publishes a spec sheet for the 57-2579A, and it is linked directly from the product information. That document is where you confirm the contact and electrical detail before you commit it to a control panel drawing.
