Schneider Electric XVBC2B3 Harmony XVB Green 70 mm Indicator

XVBC2B3 green 70 mm steady indicator bank unit

The XVBC2B3 is a Schneider Electric product listed in the datasheet as: Indicator bank, Harmony XVB, illuminated unit, plastic, green, 70mm, steady, integral LED, 24V AC DC. The XVBC2B3 is a green Harmony XVB illuminated unit of 70 mm with steady light, integral LED and 24 V AC/DC supply. It forms one tier in a stacked signal tower. Seven Star LLC supplies the XVBC2B3 in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference: XVBC2 is the 70 mm illuminated unit, B marks the LED version and 3 the green colour. The datasheet shows it as discontinued.

Technical specifications of the XVBC2B3

Light and supply data of the XVBC2B3

Supply voltage: 24 V AC/DC.

The datasheet lists the lens, voltage and consumption. Green typically means normal run or ready.

Stacking the XVBC2B3 with other units

Units stack onto a base with a tube; add yellow and red tiers. The XVBC2B8 is the yellow unit of the same family.

Confirm the successor.

The datasheet downloaded for this page carries lifecycle notices: Discontinued on: Dec 31, 2025; End-of-service on: Jul 1, 2026. For a plant that already runs this reference that makes the XVBC2B3 a spare-and-replacement item, and it is worth fixing the stock level and the long-term successor plan at the same time. We can discuss compatible alternatives once we know the installation.

Dimensions, environment and approvals of the XVBC2B3

The XVBC2B3 weighs 0.15 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: IP65 on fixing base XVBZ0. IEC 60529; IP66 on base unit IEC 60529. Standards listed: IEC 60947-5-1. Certifications listed for this reference: CCC; EAC; CSA C22-2 No 14; UL 508.

Signal towers are often judged only by colour, yet the details of the XVBC2B3 matter for a good installation. The 70 mm unit has a lens that spreads light around, so the tower should be placed where operators see it from the main work positions. Steady green is usually reserved for normal operation, and the meaning of each colour should be written in the machine manual so that new operators do not guess. The LED version has a long life and low heat, but the lens can still fade in strong sunshine over years. Avoid stacking more units than the base is rated for, and check the voltage rating of each unit, since mixing 24 V and 230 V units in one tower is not allowed. Because the datasheet lists this reference as discontinued, plan for a successor and take a note of base and tube compatibility. Keep spare lenses and LED units for the towers at the busiest sites. For a signal tower the control signal normally comes from a PLC output, and the unit takes the same 24 V AC/DC supply as other devices in the panel, so no special supply is needed. If the tower is at the end of a long cable run, check the voltage at the lamp under load, because low voltage reduces brightness. A short test routine in the PLC that lights every colour at power-up helps operators to detect a failed LED immediately instead of at the moment a real alarm is needed. Note the position in the stack when ordering spares, since the stack order is part of the plant standard.
