Schneider Electric XA2ES442 XA2E E-stop, Dia 30 turn to release
Description
XA2ES442: XA2E emergency stop button, red mushroom Ø30 mm, turn to release
The XA2ES442 is a Schneider Electric Harmony XA2 complete emergency switching off push-button in the XA2E plastic series. It has a red mushroom head of 30 mm diameter, a turn to release reset action, and one normally closed contact with positive opening. It fits a 22 mm panel hole. Seven Star LLC supplies the XA2ES442 in Oman and the GCC as an independent supplier in Muscat.
The datasheet used for this page is dated 8 Nov 2026 and shows the reference as discontinued: discontinuation is dated 9 Jan 2026 and end of service 1 Jul 2026. Treat availability as stock-dependent and ask about replacement options when you enquire. Some catalogue titles describe this reference with a black head; the datasheet states a red mushroom of 30 mm and the product photo shows red.

How the XA2ES442 latches and resets
The head locks down when pressed and is released by turning it, after which the contact recloses. The turn action is easy to teach and hard to trigger by accident. The contact is 1 NC and the datasheet lists positive opening (with NC contact), meaning the contact is forced open mechanically when the head is pressed rather than relying on a spring alone.
Resetting the button does not restart the machine. A correct emergency-stop circuit keeps the machine stopped until a separate deliberate restart command is given, and the control design, not the XA2ES442, is responsible for that behaviour.
Head size and mounting of the XA2ES442
The 30 mm mushroom is the compact size, useful where panel space is tight. The body mounts in a 22 mm hole, measures 42 mm wide, 30 mm high and 73.7 mm deep and weighs 0.056 kg. Wiring goes to screw clamp terminals for up to 2 x 1.5 mm² or 1 x 2.5 mm² (minimum 0.5 mm²), or 6.3 mm Faston tabs, tightened to 0.8 N.m.
Fit the button where an operator can reach it without crossing a hazard, keep the surrounding area clear, and use a yellow background legend plate if your site standard requires one, as the datasheet does not describe a legend plate for this reference.
Electrical ratings and durability of the XA2ES442
The rated operational current is 3 A at 240 V AC-15 and 0.27 A at 250 V DC-13; rated insulation voltage is 600 V and impulse withstand voltage 6 kV. A 10 A gL fuse is named as short-circuit protection. Electrical durability is 500000 cycles at 3 A AC-15 / 230 V and 500000 cycles at 0.2 A DC-13 / 110 V. Mechanical durability is 100000 cycles, which is intended for a device that is rarely operated, and for functional tests rather than daily use.
Use the NC contact in a safety relay or control circuit and test the circuit at regular intervals; the datasheet confirms the contact only, not the safety category of the full circuit.
Where the XA2ES442 is used in Oman and the GCC
Emergency-stop buttons appear on pump skids, compressors, conveyors, packaging lines and machine guards in plants across the region. This unit, with its red mushroom of 30 mm and turn to release reset, is typically wired into a safety relay or a main contactor circuit so that pressing it removes drive power.
Heat and dust can cause plastic to age, so inspect the head and the latching action periodically, and test each button during planned shutdowns.
Spares and testing of the XA2ES442
The datasheet marks this reference as discontinued, so it is mainly bought as a like-for-like spare. Check the head diameter, the release action and the contact type against the unit being replaced; swapping a turn-release head for a push-pull head changes how operators reset the station.
After fitting, press and release the button, measure that the NC contact opens and recloses, and confirm the machine stops. Record the reference this unit in the safety documentation.

About brand
Schneider Electric is the French group for energy management and industrial automation: low and medium voltage switchgear and circuit breakers, motor control, drives, PLCs, power monitoring, UPS systems and building management. Its history goes back to 1836, when the brothers Adolphe and Eugène Schneider took over the iron and steel works at Le Creusot in Burgundy. Over the 20th century the company left steel and heavy engineering and became an electrical group through acquisitions such as Merlin Gerin, Télémécanique, Square D and Modicon. Its head office is in Rueil-Malmaison near Paris, and its shares are listed on Euronext Paris.

Milestones
- 1836: The Schneider brothers acquire the Le Creusot works; the business grows in steel, locomotives and heavy engineering.
- 1975: First investment in Merlin Gerin, a French maker of electrical distribution equipment.
- 1988–1992: Télémécanique, Square D (USA) and Merlin Gerin join the group, making it an electrical specialist.
- 1997: Modicon, the company behind the first programmable logic controller, joins the group.

Choosing Schneider Electric breakers and motor control
Circuit breakers are chosen by current and breaking capacity. Acti9 miniature circuit breakers (iC60, C120) protect final circuits up to 125 A. ComPacT NSX molded case breakers cover about 16 to 630 A, and the letter after the frame size sets the breaking capacity: B, F, N, H, S, L from lowest to highest. MasterPacT air circuit breakers are used as main incomers on large switchboards. For motors, a TeSys contactor with an LRD overload relay or a GV2 motor circuit breaker suits direct starting, an Altistart soft starter reduces starting current, and an Altivar drive controls speed. The breaking capacity must always be at least the prospective short-circuit current at the point of installation.
Where Schneider Electric products are used
In Oman and the GCC, Schneider Electric equipment is found in main and sub-main switchboards of commercial and residential buildings, motor control centres in water, oil and gas and industrial plants, substations protected by Sepam and Easergy relays, data centres powered by Galaxy and APC UPS systems, and buildings controlled by EcoStruxure Building Operation.
APC by Schneider Electric: UPS and critical power
Since 2007, APC has been part of Schneider Electric and is now its product brand for uninterruptible power supplies, replacement batteries, battery packs, network management cards and rack power distribution. Our APC catalogue covers Smart-UPS line-interactive and on-line models, Easy UPS On-Line, the modular Symmetra LX, RM and PX ranges, Silcon three-phase systems and their spare part kits, and the RBC cartridges that keep them running. Schneider Electric breakers, drives and PLCs can be quoted together with APC UPS systems in one request.
