XB5AD21 2-position stay-put selector switch with black handle
The XB5AD21 is a Schneider Electric product listed in the datasheet as: Harmony, 22mm Push Button, 2 position selector switch, black, maintained, 1 NO, marked OFF ON. The XB5AD21 is a 22 mm two-position selector switch from the plastic Harmony XB5 range. It has a standard black handle that stays in the chosen position and one normally-open contact. Seven Star LLC supplies the XB5AD21 in Oman and the GCC as an independent supplier based in Muscat.
Reading the reference: XB5 is the plastic range, AD the selector with standard handle, 2 the two positions and 1 the one-NO contact block, as confirmed by the operator position (2 positions at 90 degrees) and contacts rows.

Operator and contact data
Operator: stay put. Positions: 2 positions 90°. Handle: Black standard handle. Contacts: 1 NO. Operating torque: 0.14 N.m NO changing electrical state. Mechanical life: 1000000 cycles. Contact material: Silver alloy (Ag/Ni). Weight: 0.043 kg.
A stay-put selector holds its position until moved. Typical functions are manual/auto, local/remote and on/off. With one NO contact, it gives one signal; for more functions, additional contact blocks can be added.
Using the XB5AD21 for mode selection
Wire the contact to a PLC input or into a control circuit. For manual/off/auto with three positions use the three-position version; this one is purely two positions.
Mounting, wiring and accessories are the same as for the other XB5 operators: a 22 mm hole, a fixing collar and screw-clamp terminals.
Selection checklist for the XB5AD21
- Number of positions: 2.
- Stay-put versus spring return.
- Handle shape: standard black.
- Contact configuration.
- Panel hole and depth.
- Environment and protection.
Installing and maintaining the XB5AD21
Insert in the 22 mm hole, fix with the collar, and connect the contact block. Add a legend plate to identify the positions.
Check contact resistance if used with PLC inputs at low current, and replace the contact block if intermittent. The mechanical life is long, so most failures are from the contact block.
Typical applications of the XB5AD21 in Oman and the GCC
Mode selectors on panels, motor starters, pump controls and test-bench switches in the region.
Dimensions, environment and approvals of the XB5AD21
For the XB5AD21, plan the mounting space from the datasheet: 30 mm (W) x 42 mm (H) x 70 mm (D). The XB5AD21 weighs 0.043 kg. Mounting, derating and enclosure choices follow the environmental data below, which should be compared with the actual panel temperature and the dust and humidity of the site in Oman and the GCC.
Ambient temperature limits in the datasheet: -40 to 70 °C. Ingress protection: IP67 IEC 60529; IP69; IP69K. Vibration resistance: 5 gn (f= 2 to 500 Hz) conforming to IEC 60068-2-6. Shock resistance: 30 gn 18 ms half sine wave acceleration IEC 60068-2-27; 50 gn 11 ms half sine wave acceleration IEC 60068-2-27. Standards listed: IEC 60947-1; IEC 60947-5-4; IEC 60947-5-1; JIS C8201-5-1; UL 508; CSA C22.2 No 14; JIS C8201-1.

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.
- 1999: The group takes the name Schneider Electric.
- 2007 and 2014: APC (UPS and data centre power) and Invensys (process automation) are acquired.
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.
