Product Overview
Allen-Bradley Bulletin 598 Emergency Stop Station, Type 4/4X, with 40mm Mushroom Operator and Two 22mm Contact Blocks
Condition
Used. Removed from a lightly used solar panel manufacturing line, with only minor cosmetic wear. In the photos the yellow housing is clean, with light scuffs and handling marks and no cracks, and the black EMERGENCY STOP legend around the operator is crisp. All four white captive cover screws are present and the black perimeter gasket sits unbroken in its groove. The label inside the base reads Allen-Bradley, BUL. 598, TYPE 4/4X IP66, PUSH BUTTON ENCLOSURE, CAT. 598-1PB22Y, SER. B, MADE IN KOREA, with a UL mark listed A-1217 for industrial control panel enclosures, a CE mark, and 09/25/09 printed beside the barcode. Inside, two contact blocks are latched to the operator collar: an Allen-Bradley 800F-X01S SER. A self-monitoring block made in the Czech Republic and a Sprecher+Schuh D7-X01 SER. A auxiliary block made in Switzerland, marked NC at its terminals. The field wiring is still attached, with black conductors in red insulated ferrules, printed wire numbers on the insulation, a green ground lead, and a black liquid-tight cord grip holding a short grey cable stub. The molded underside carries the HI BOX name, MADE IN KOREA, and ABS, PC and PBT material marks. Not electrically tested here, so the photos and this description are the spec.

Product Overview
Bulletin 598 is Allen-Bradley's line of non-metallic push button enclosures, and 598-1PB22Y is the single-hole 22mm version. This one is built out as a complete emergency stop station: the cover carries a 40mm push-pull mushroom operator, the 800FP-MT44, which latches down when struck and releases with a twist, and the 22mm collar behind it holds two contact blocks side by side. The Allen-Bradley 800F-X01S SER. A self-monitoring block is printed Ui 690V, Uimp 4kV, Ithe 10A, AC-15 A600, DC-13 Q600, EN/IEC 60947-5-1, and the Sprecher+Schuh D7-X01 SER. A beside it carries the same printed rating set. The enclosure label calls out Type 4/4X and IP66, which is why a box like this ends up on a wash-down line, an outdoor conveyor or a machine skid rather than tucked inside a dry control cabinet. The same label reminds the installer that bonding between conduits must be provided to maintain the Type rating.

Frequently Asked Questions
What exactly comes in the box, and is anything missing?
What you see in the photos is what ships: the 598-1PB22Y enclosure with its gasketed cover and four captive screws, the 40mm mushroom operator mounted through the single 22mm hole, the Allen-Bradley 800F-X01S self-monitoring contact block, the Sprecher+Schuh D7-X01 auxiliary block, the black liquid-tight cord grip, and the short length of grey cable and ferruled leads still attached from the machine it came off. There is no mounting hardware, gland nut spares or documentation beyond that.
Is it wired and ready to drop in?
It is wired as it was pulled, not terminated for your panel. The leads are cut short and ferruled, the ground conductor is green, and the cord grip is already fitted, so you will land your own cable and re-terminate at the blocks. The base has corner holes for mounting screws and threaded inserts in the floor, and the label notes that conduit bonding is required if you want to keep the Type rating intact.
What does the self-monitoring contact block do?
Allen-Bradley's self-monitoring 800F blocks are designed so that a block separating from the operator opens the circuit instead of leaving it closed, which is the failure a plain auxiliary block will not catch. Confirm the exact contact arrangement and the self-monitoring behavior against Allen-Bradley's 800F documentation before you build it into a safety function.
Can I use the ratings printed on the contact blocks as-is?
Those figures are read straight off the block labels in the photos: Ui 690V, Uimp 4kV, Ithe 10A, AC-15 A600, DC-13 Q600, EN/IEC 60947-5-1. They describe what the blocks were rated for when they left the factory, not a test result from us. Verify against the current datasheets for your application voltage and utilization category.
What am I taking on by buying a used stop station instead of a new one?
You are taking on the part of the risk we cannot retire for you. This assembly came off a lightly used solar panel line, and it photographed clean: gasket in place, legend sharp, both blocks and the operator present. We did not put a meter on it, so there is no continuity check, no actuation cycle count and no dielectric test behind this listing. Inspect it, test the contacts, and satisfy your own safety review before it protects anyone. There is one of these, the photos are the spec, and nothing in the description softens what the camera shows. It clears our free shipping line on its own, and it leaves the Idaho warehouse the same or next business day.
A stop button is the one control on a machine that everyone hopes stays untouched, and this one came off a lightly used solar panel line with its gasket seated, its legend sharp and both blocks still latched to the operator. Wire it into your next build and give it the same job.
