Schneider Electric XA2EG43 XA2E key selector, 2 pos, 2 NO

XA2EG43: XA2E key selector switch, 2 positions 90°, 2 NO

The XA2EG43 is a Schneider Electric Harmony XA2 complete key selector switch in the XA2E plastic series. It has 2 positions 90°, a stay-put operator and 2 NO, and it is operated with key number 455. The key can be withdrawn in the left and right positions. Seven Star LLC supplies the XA2EG43 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. The key switch is a deliberate-access device: only a person holding the key can change the selected position.

Technical specifications of the XA2EG43

Key, positions and withdrawal on the XA2EG43

The datasheet lists key number 455 and withdrawal in the left and right positions. With withdrawal at both ends, the key can be taken out whichever of the two positions is selected, so either state can be locked in. The switch has 2 positions 90°; the handle is a key cylinder rather than a lever.

Treat key number as a part of the order, not an afterthought: all switches that must share one key need the same number, while switches that must not share a key need different ones. Ask which key arrangement your site rule uses before ordering.

Mounting and wiring of the XA2EG43

The body fits a 22.5 mm panel hole with a fixing-nut torque of 2–2.4 N.m. Overall size is 30 mm wide, 42 mm high and 85.7 mm deep and the net weight is 0.078 kg. The extra depth compared with a lever selector is the key cylinder, so check clearance behind the door. 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.

The 2 NO contacts are normally open: with two contacts, each closes on a different side. Mark the schematic with the key number and the position used for each contact.

Electrical ratings and life of the XA2EG43

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, noticeably lower than a push-button because a key cylinder is a heavier mechanism.

Key switches are normally used for infrequent changes of mode, so that figure is usually adequate; they are not meant for rapid cycling.

Where the XA2EG43 is used in Oman and the GCC

Key selectors restrict who can change a mode: bypass or override switches on safety interlocks, local-remote selection on pump and compressor panels, test or maintenance modes, and access control on machine guards. On Gulf sites with contractors on shift, a key held by the supervisor prevents a casual change.

The XA2EG43 has a front rating below that of push-buttons, so in sandy, humid or wash-down areas use it inside a closed enclosure or under a cover, and keep the key cylinder clean.

Commissioning and spares for the XA2EG43

As the datasheet marks this reference as discontinued, spares for existing key-operated panels are the likely need. Match key number, positions, contact count and withdrawal position with the unit being replaced, since two key switches that look the same can behave differently.

After installation, test the switch with the key in each position, confirm withdrawal behaves as intended and record who holds the keys. Lubricate or clean the cylinder only with products suitable for plastic and metal locks, and keep a spare key set in a controlled place together with the reference this unit in the panel records.
