Schneider Electric XB5EVB4 Red Pilot Light 24 V AC/DC

XB5EVB4: red 24 V AC/DC Harmony XB5 monolithic pilot light

The XB5EVB4 is a Schneider Electric Harmony XB5 monolithic pilot light for a 22 mm panel hole. It has a dark grey plastic bezel, a round red plain lens, an integral universal LED and a rated supply of 24 V AC/DC at 50/60 Hz. Seven Star LLC supplies the XB5EVB4 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 (4) sets the lens colour. The XB5EVB4 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.

Selection checklist and RFQ information for XB5EVB4

Send the points below so that the part number can be confirmed against the datasheet and checked for availability in one reply.

• Part number XB5EVB4 and the required quantity.
• The lamp circuit supply, here 24 V AC/DC at 50/60 Hz.
• The lens colour (red) and its meaning on your legend.
• Panel thickness at the hole, against the 1 to 6 mm clamping range.
• Rear clearance behind the panel, against the body depth.
• Any approval needed by the project, compared with the datasheet listing.
• Delivery location in Oman or the GCC and the lead time you need.

Sealing, immunity and approvals of the XB5EVB4

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 UL listed, CSA. Marine and offshore buyers sometimes ask for ship-classification marks; XB5EVB4 should only be accepted against a requirement that appears in the datasheet for this exact reference, and this one lists no marine approval.

Mounting and wiring of the XB5EVB4

The XB5EVB4 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 red indicator belongs

Red is the colour operators look at first. Standards-minded panel builders reserve it for faults, trips, danger and emergency conditions, or for a stopped state when the plant specification says so, so check the project colour table before assigning it. The plain lens of the this unit carries no legend, so the function is normally identified by a nameplate or an engraved label beside it. Siblings in the same colour, XB5EVM4, 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.

Supply, LED and signalling of the XB5EVB4

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 XB5EVB3, 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 XB5EVB4 in Oman and the GCC

Typical homes for this unit are starter doors, control desks, skid panels, building service boards and workshop machines across Oman and the GCC. Process plants use such lamps to show run, ready and fault states on auxiliary panels, while utilities fit them to pump houses and distribution boards where a clear, sealed indicator is easier to maintain than a lamp holder.

On a coastal site the sealed lens keeps dust and humidity out; the light plastic bezel suits large doors carrying dozens of lamps.

The XB5EV group and how XB5EVB4 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 red 24 V AC/DC member.
