Schneider Electric XA2EH051 XA2E yellow push-button 1 NO
Description
XA2EH051: yellow push-push XA2E push-button, 1 NO
The XA2EH051 is a Schneider Electric Harmony XA2 complete push-button in the XA2E plastic series for a 22 mm panel hole. It is a yellow flush push-push push-button with 1 NO, with a plastic bezel and fixing collar. Seven Star LLC supplies the XA2EH051 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 1 Aug 2025. Treat availability as stock-dependent and ask about replacement options when you enquire. Reading the reference: XA2E is the component family, and the title of the product gives the cap colour, the operator action and the contact block. The contact is a 1 NO with slow-break operation, so this normally open contact closes when the button is pressed.

Cap colour and contact choice on the XA2EH051
Yellow conventionally marks interventions for abnormal conditions, for example to override or suppress an automatic cycle. On the XA2EH051 the contact is 1 NO. A normally open contact is the natural choice for a start or command input, because a broken wire then reads as no command.
The unmarked cap needs a legend plate or engraved label next to it, so mount a nameplate under the button. The push-push action latches the contact on one press and releases it on the next, so it can serve as a simple maintained selection without a separate selector switch.
Operator, mounting and wiring of the XA2EH051
The body mounts in a 22.5 mm hole with the fixing nut tightened to 2–2.4 N.m and a panel thickness of 1–5 mm. Overall size is 30 mm wide, 42 mm high and 67.7 mm deep, and the net weight is 0.04 kg. The operator is allowed in any position.
Wiring goes to screw clamp terminals taking up to 2 x 1.5 mm² or 1 x 2.5 mm², with 6.3 mm Faston tabs as an alternative. Tighten the terminals to 0.8 N.m. The datasheet asks for a 10 A gL fuse as short-circuit protection of the contact circuit.
Electrical ratings and durability of the XA2EH051
The rated operational current is 3 A at 240 V AC-15 and 0.27 A at 250 V DC-13, with a conventional thermal current of 10 A. Rated insulation voltage is 600 V and the impulse withstand voltage is 6 kV. For logic-level circuits the datasheet quotes reliability of better than 10-8 failures at 24 V.
Mechanical durability is 1000000 cycles; electrical durability is 500000 cycles at 3 A AC-15 / 230 V and 500000 cycles at 0.2 A DC-13 / 110 V. For a button pressed a few hundred times a day, the contact will outlast a typical panel; for high-rate use, check the cycle figures against the real duty.
Environment and approvals for the XA2EH051
The device is rated IP65 at the front 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). Standards named are IEC 60947-5-1; IEC 60947-1; GB 14048.5; GB 14048.1, with CCC and CE certification.
Environmental data on the datasheet: the datasheet gives a total lifecycle carbon footprint of 0.4 kg CO2 eq., of which 0.3 kg is the manufacturing phase and 0 kg the use phase; EU RoHS status shown as compliant.

How the XA2EH051 compares with other XA2E push-buttons
The XA2E flush push-buttons share the same body, size and wiring; they differ in cap colour, legend, contact type and action. The group below is taken from the datasheets of the references in this range.
| Reference | Colour | Contacts | Operator | Profile |
|---|---|---|---|---|
| XA2EA11 | White | 1 NO | Spring return | White flush, unmarked |
| XA2EA21 | Black | 1 NO | Spring return | Black flush, unmarked |
| XA2EA31 | Green | 1 NO | Spring return | Green flush, unmarked |
| XA2EA42 | Red | 1 NC | Spring return | Red flush, unmarked |
| XA2EA4342 | Red | 1 NC | Spring return | Red flush, STOP (white) |
| XA2EH051 (this page) | Yellow | 1 NO | Push-push | Yellow flush, unmarked |
Choose by function first (start, stop, command), then by contact type, and keep one colour per function across the whole panel.

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.

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.
