Product Overview
Allen-Bradley 598-1PB22Y Emergency Stop Station with 800FP-MT44 Mushroom Operator and Two 800F Contact Blocks
Condition
Used, pulled from a solar panel manufacturing line. In the photos the yellow ABS enclosure shows scuffs, fine scratches and dust settled in the molded EMERGENCY STOP ring, with a small white plant tag still stuck to the lid; the tag number differs from unit to unit, so yours may not match the one pictured. Inside, the factory label is clean and fully legible: Allen-Bradley BUL.598, TYPE 4/4X IP66, PUSH BUTTON ENCLOSURE, CAT. 598-1PB22Y, MADE IN KOREA. Both contact blocks read Allen-Bradley 800F SER. A with the printing sharp, one 800F-X01S made in the Czech Republic and one 800F-X01 made in Switzerland. Field wiring still carries clear numbered ferrules from the machine harness, and a short grey cable stub passes through a black M20 x 1.5 gland. Removed from service in working order with cosmetic wear only. We publish no bench test data for this station, so the photos are the spec and the continuity check is yours to make.

Product Overview
This is a complete local emergency stop station, assembled the way a plant electrician assembles one: an Allen-Bradley Bulletin 598 single-hole push button enclosure, catalog 598-1PB22Y, rated Type 4/4X IP66 and molded in yellow ABS by Hibox in Korea, fitted with an 800FP-MT44 push-pull mushroom operator and two 800F Series A contact blocks. The operator works the way the cap is marked: push the red head to stop, then rotate it in the direction of the molded white arrows to unlock and disengage the latched stop. The block pair is an 800F-X01S self-monitoring block and a standard 800F-X01, and both label faces read Ui 690V, Uimp 4kV, Ithe 10A, AC-15 A600, DC-13 Q600 to EN/IEC 60947-5-1, alongside UL Listed A191 industrial control equipment, CSA, CE and CCC A000478 marks. The base underside is molded with dimension marks reading 62 and 92 between the four corner holes, and the lid is punched for one 22 mm operator, so the station bolts to a machine frame or column and takes its cable through the fitted M20 x 1.5 gland.

Frequently Asked Questions
What exactly is in the assembly?
The 598-1PB22Y enclosure, the 800FP-MT44 push-pull mushroom operator, and two 800F Series A contact blocks, one 800F-X01S and one 800F-X01. The photographed units are also fitted with a black M20 x 1.5 gland and a short grey cable stub left over from the machine harness; treat those as photographed rather than promised, and ask us first if the gland matters to your build.
How does the mushroom head release?
Push the red head down and the stop latches in. To clear it, rotate the head the way the molded white arrows on the cap point: the twist unlocks the latch and the operator disengages and comes back out. That is what those arrows are there to tell the operator standing at the machine, and it is the reset sequence to build your circuit around on this 800FP-MT44 push-pull head.
Can a used stop station go into a safety-rated circuit?
That call belongs to whoever validates the safety function on your machine, not to us. What we can hand you is what is printed on the parts: the 800F-X01S is the self-monitoring version, both blocks carry EN/IEC 60947-5-1 and UL Listed A191 industrial control equipment marks, and this station came off a production line rather than out of a sealed box. Buyers use pulls like this for training rigs, spares and non-safety stop circuits every day, and the ones who put them back into safety duty test and document them first.
Can I fit a different 22 mm operator in the enclosure?
The 598 lid is punched for one 22 mm head, and the photos show the black 800F latch collar that clamps the operator to the lid, so the mechanics are straightforward. Keep the enclosure label's own warning in mind if the Type 4/4X IP66 rating matters to you: it calls for UL Listed or Recognized components with the same type rating.
Is a used stop station off a solar line worth taking on?
Here is the honest version. This is a used pull, not new stock. It carries scuffs, a leftover plant tag and machine harness ferrules, we publish no bench test data for it, and the photos are the spec, so the continuity check before commissioning is yours to make. What you get for taking that on is a fully identified assembly with every part number still legible, enclosure catalog and both block catalogs photographed, instead of an unmarked yellow box from an auction pallet. This item clears the free shipping line on its own, and orders leave our Idaho warehouse the same or next business day.
A stop button earns its keep by never being needed, and this one did that job on a solar panel line until the line came down. Put it back on a machine and it goes right back to standing by for the one second it was built for.
