Electrical ratings and durability of the XA2ES542
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.
Environment, packaging and approvals for the XA2ES542
The front is rated IP65 with impact rating IK03. Operating temperature is -25–55 °C and storage -40–70 °C. Vibration resistance is 10 gn (f= 40…500 Hz) and shock resistance 70 gn (duration = 11 ms).

The XA2ES542 compared with other XA2E emergency stops
The three emergency-stop references in this range of references share the same body and NC contact. They differ in head diameter and release action.
| Reference | Head | Release | Contact | Depth | Weight |
|---|---|---|---|---|---|
| XA2ES442 | Red mushroom Ø 30 mm | Turn to release | 1 NC | 73.7 mm | 0.056 kg |
| XA2ES542 (this page) | Red mushroom Ø 40 mm | Turn to release | 1 NC | 74.2 mm | 0.058 kg |
| XA2ET42 | Red mushroom Ø 40 mm | Push-pull | 1 NC | 74.2 mm | 0.088 kg |
Choose by release action your site uses and by how large the head must be for reach.
Where the XA2ES542 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 40 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 XA2ES542
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.

Ordering Schneider Electric products: what we need
Send the commercial reference from the label (for example LC1D18M7 or ATV320U22N4C). For breakers, confirm the rated current, number of poles, breaking capacity and trip unit. For contactors, give the coil voltage. For drives, give the motor power and supply voltage. APC products are listed on their own brand page.
