Schneider Electric ZB6EB4B XB6 Red LED Light Block 12-24 V

ZB6EB4B: Harmony XB6 red LED light block, 12–24 V

The ZB6EB4B is a Schneider Electric Harmony XB6 complete body for pilot lights, supplied with a red integral LED and a 12 to 24 V AC/DC supply. Seven Star LLC supplies the ZB6EB4B in Oman and the GCC as an independent supplier in Muscat, mostly for builders of compact control panels and operator stations that use the small XB6 format.

The datasheet calls it a complete body for pilot lights and lists a bulb base of integral LED, which means the LED is part of the unit and cannot be exchanged on its own. The unit is sold in a pack of five, so a quotation request should state the number of packs or the number of pieces, not the number of lit positions only.

Immunity, emission and approvals

The datasheet quotes resistance to fast transients of 2 kV, radiated electromagnetic fields of 10 V/m, and electrostatic discharge of 6 kV on contact and 8 kV in air. Electromagnetic emission is Class B, and the protection class against electric shock is Class II. These values matter in panels that also hold drives or contactors that generate switching noise.

Listed certifications are CSA, UL, CCC and GOST, and the standards include IEC 60947-1, IEC 60947-5-1, IEC 60947-5-5, UL 508 and CSA C22.2 No 14. As always, check that an approval required by the project appears on the datasheet for ZB6EB4B itself and not for another part of the range.

Wiring, testing and spares

Connect the faston tabs with insulated receptacles that match the 2.8 × 0.5 mm size, and observe the (+) and (-) markings on a DC supply. The unit works in any position. After the panel is closed, energise the circuit at the supply voltage to be used, because an LED seen to light at 24 V on the bench may look dimmer at 12 V in a lit workshop.

Since the LED cannot be changed separately, hold a few spare pieces: one failed ZB6EB4B is replaced as a whole, and a pack of five covers a typical panel for several years of service.

Technical data of the ZB6EB4B

Where small pilot lights are used in Oman and the GCC

Compact indicators like ZB6EB4B fill the front of instrument panels, test benches, small packaged skids, battery chargers and machine control boxes where space is short. In the Gulf they are found in utility cabinets for water treatment and power distribution, and in enclosures cooled only by a fan, where a low current draw of 15 mA per lamp keeps self-heating small.

Supply, current draw and light behaviour

The rated supply is 12 to 24 V AC/DC, and the datasheet gives limits of 6 to 30 V AC/DC with a steady signal and a current consumption of 15 mA. The wide window lets ZB6EB4B run from a 12 V battery system, a 24 V DC control supply or a 24 V AC transformer winding without a different part number for each. The datasheet allows operation down to 6 V, although the brightness of any LED depends on the voltage that actually reaches it.

The light block is supplied directly, with no series resistor or transformer required, and the connection is made by faston tabs of 2.8 × 0.5 mm marked with the ISO symbol (+ -)PL. Polarity marking applies on DC, while on AC the connection is non-polar.

Information to send with an RFQ for ZB6EB4B

The points below let us confirm the part number against the datasheet and check stock in one reply.

• Part number ZB6EB4B and the number of packs of five.
• The supply voltage and whether it is AC or DC.
• The LED colour required (this reference is red).
• Hole pattern and panel thickness for the XB6 head.
• Terminal type needed, here faston 2.8 × 0.5 mm.
• Delivery location and lead time.

For replacements, send a photo of the old light block and its label.

The XB6 format and where ZB6EB4B fits

The Harmony XB6 range is the compact format of the Harmony family. The datasheet for this reference lists a height of 14 mm and a depth of 58 mm, with a weight of 0.003 kg per piece, which makes it among the lightest items in the group. The unit goes behind an XB6 pilot-light head, and the datasheet describes it as a complete body, so the collar function is included.

For contacts in the same format, the lane includes ZB6Z1B, a 1NO complete body with faston terminals. Together with a head from the same range, a pilot light and a push-button can share one grid of holes.
