Product Overview
The Square D 9001JT1-L29 is a compact push-to-test pilot light from the 9001J Series B line, built for panel and enclosure indicator duty. It carries a blue lens and mounts through an 11/16 inch (0.69 inch) panel hole, sealed with the gasket and locking nut shown in the photos. Line input is 110/120VAC at 50/60Hz; internally the unit steps that down through a transformer to drive a low-voltage replacement lamp, type 755 or 6MB. Wiring runs to three screw terminals on the back of the housing, corresponding to L1, L2, and C on the wiring diagram printed on the unit's own label, sized for 14 AWG wire. The lens body is plastic, and the unit carries UL Listing (Ind. Cont. Eq. 572A) and CSA approval, with a NEMA 4/13 rated enclosure. Made in the USA.

Frequently Asked Questions
What lamp does the 9001JT1-L29 use?
It takes replacement lamp type 755 or 6MB, per the label on the unit. Line input is 110/120VAC, but an internal transformer steps that down to drive the low-voltage lamp, so no separate transformer is needed to run it.
What size hole does it mount in?
The bushing is sized for an 11/16 inch (0.69 inch) panel cutout, with the gasket, washer, and locking nut shown in the photos handling the panel seal.
How do I wire it?
Three screw terminals on the back correspond to L1, L2, and C on the wiring diagram printed on the unit's own label, and are sized for 14 AWG wire.
Is this a full replacement unit or just a lens?
It is the complete pilot light assembly: lens, transformer body, mounting bushing, gasket, and nut, ready to wire into your panel. Not confirmed - verify the lamp is included before use, since the label calls out lamp type 755 or 6MB as the correct replacement.
Why buy this one instead of a used pull or an unsorted lot?
This is a single, New 9001JT1-L29, photographed and confirmed rather than an unknown quantity from a used lot or grab-bag assortment. Shipping is a flat $8, free once your order passes $28, and it leaves our Idaho warehouse the same or next business day.
A blue pilot light spends most of its life just sitting there, doing its job by not needing attention - until the day you push the lens and it tells you, right then, whether the lamp or the circuit behind it is still good. Wire this one in and let it stand its post on your panel.
