Schneider Electric XB5EVB3 Green Pilot Light 24 V AC/DC

XB5EVB3: green 24 V AC/DC Harmony XB5 monolithic pilot light

The XB5EVB3 is a Schneider Electric Harmony XB5 monolithic pilot light for a 22 mm panel hole. It has a dark grey plastic bezel, a round green plain lens, an integral universal LED and a rated supply of 24 V AC/DC at 50/60 Hz. Seven Star LLC supplies the XB5EVB3 in Oman and the GCC as an independent supplier based in Muscat, normally to panel builders, maintenance stores and EPC contractors who need a light, economical indicator for a control panel door.

The datasheet titles of the 6 references in this group suggest a reading that we offer as our own interpretation, not a manufacturer ordering table: XB5EV is the plastic pilot light with an integral LED, the letter after it (B) sets the supply, and the digit (3) sets the lens colour. The XB5EVB3 is built as a monolithic body, meaning the lens and the electrical part are one moulded unit rather than a head on a separate block.

Mounting and wiring of the XB5EVB3

The XB5EVB3 mounts in a standard 22.5 mm round hole, and the dimension drawing in the datasheet gives a clamping thickness of 1 to 6 mm. The body measures 29 mm high, 29 mm wide and 54 mm deep behind the panel face and weighs 0.038 kg. The rear depth is the figure to check on shallow doors and when several lamps are stacked close to a terminal rail.

Connection is by screw clamp terminals marked (X1-X2)PL under the ISO numbering. The datasheet permits up to two conductors of 1.5 mm² with cable ends, or a single conductor from 0.22 mm² up to two of 2.5 mm² without ends. The head resists a high-pressure washer at 7000000 Pa and 55 °C from 0.1 m according to the datasheet, a useful figure for washdown areas.

Where a green indicator belongs

Green is conventionally the normal or permitted colour: running, ready, valve open or equipment healthy. Because operators read green as permission to proceed, it should not be reused for a signal that only means energised. The plain lens of the XB5EVB3 carries no legend, so the function is normally identified by a nameplate or an engraved label beside it. Siblings in the same colour, XB5EVM3, differ only in supply voltage. When several lamps share a door, keep the colours in the same order from panel to panel so that an operator moving between plants reads each one the same way.

The XB5EV group and how XB5EVB3 differs

The 6 references share the same plain-lens round head, integral LED and 22 mm mounting. They separate on lens colour and supply voltage only, so selection is a two-step choice: first the supply of your lamp circuit, then the colour from your panel legend. The this unit is the green 24 V AC/DC member.

Sealing, immunity and approvals of the XB5EVB3

The datasheet lists protection ratings of IP66, IP67, IP69, IP69K, with UL type 4X/13 and IK05 impact protection. Storage is rated from -40 to 70 °C and operation from -25 to 70 °C, a window that covers a summer-heated switch room and most unheated outdoor cabinets. Vibration resistance is 5 gn between 12 and 500 Hz, and the shock figures are 30 gn for 18 ms and 50 gn for 11 ms.

Electromagnetic data are given too: 1 kV surge withstand, 2 kV fast transients, 10 V/m field immunity, 6 kV contact and 8 kV air electrostatic discharge, and Class B emission. The certifications listed for this reference are CSA, UL listed. Marine and offshore buyers sometimes ask for ship-classification marks; this unit should only be accepted against a requirement that appears in the datasheet for this exact reference, and this one lists no marine approval.

Technical specifications of the XB5EVB3

Supply, LED and signalling of the XB5EVB3

The 24 V AC/DC rating is the flexible low-voltage supply. One part number serves a PLC output card, a 24 V DC control bus or a 24 V AC transformer winding, which suits panels that mix supplies and avoids carrying two stock references. Low-voltage lamp circuits also allow lighter wiring and are often preferred inside machine panels. Other references in this group with the same supply include XB5EVB4, XB5EVB5, XB5EVB8, so a mixed row of colours can share one lamp circuit.

The datasheet lists the supply limits as 19.2–30 V DC and 21.6–26.4 V AC and the current consumption as 18 mA, which is small enough for a long row of lamps on one control fuse. The light source is a universal LED with an integral base, so there is no bulb to change. The stated service life is 100000 h at rated voltage and 25 °C, and the signalling type is steady. A note at the head of the datasheet says a change in appearance may be seen on the product without affecting function or safety, and that this keeps it compatible with the manufacturer’s universal LED blocks.

Typical uses of XB5EVB3 in Oman and the GCC

Indicators of this class, including this unit, are common on motor control panels, pump and fan starters, water treatment skids, switchgear doors and packaged equipment throughout the region. In oil and gas and petrochemical sites they sit on local control stations and auxiliary panels; in power and desalination plants they mark pump status, valve position and supply healthy.

The plastic bezel is light and economical, and the sealed head with its IP66 to IP69K list copes with dust, heat and humidity when the panel itself is properly specified.
