Schneider Electric ZBVB4 Red LED Light Block 24 V AC/DC
Description
ZBVB4: red Harmony light block, 24 V AC/DC
The ZBVB4 is a Schneider Electric light block for 22 mm Harmony XB4 and XB5 heads, with an integral red LED and a rated supply of 24 V AC/DC at 50/60 Hz. Seven Star LLC supplies the ZBVB4 in Oman and the GCC as an independent supplier in Muscat, mainly for maintenance teams who keep older illuminated stations running.
The datasheet marks this reference as discontinued on 15 Jun 2023. It was generated on 8 Nov 2026, so the product is no longer in the active range and supply depends on remaining stock or on a replacement. We state this plainly so that a buyer knows what the datasheet records before placing an RFQ. Because the datasheet also tells users that coloured LED blocks have been replaced by a single universal LED block, it is sensible to ask about both the original reference and its modern equivalent.

Typical uses in Oman and the GCC
Light blocks such as ZBVB4 are held as spares for stations on motor control centres, pump and fan panels, packaged skids and switchgear doors in oil and gas, power and water plants. Many plants in the region still run stations built with coloured LED blocks, and a stocked spare restores a lamp quickly without redesigning the panel.
Information to send with an RFQ for ZBVB4
The points below let us confirm the part number against the datasheet and check stock in one reply.
- Part number ZBVB4 and the quantity, remembering the pack size.
- The colour needed and the control supply voltage, AC or DC.
- The head the block will be used with, so that we can discuss the universal LED alternative.
- Whether stock of a discontinued item is acceptable or a current replacement is wanted.
- Delivery location and lead time.
A photo of the old block and its label helps us to confirm the match.
Colour and panel convention
Red marks faults, trips and stopped or danger states on most panels, so the lamp suits an alarm or a motor-tripped indication.
The colour of a lit station depends on both the head and the block, and on a universal LED system the head colour dominates. When ZBVB4 is used with a coloured lens, check that the lit result matches the panel legend, since a red LED behind a green lens will not give a clean green.
Immunity, approvals and environment
The datasheet quotes immunity to fast transients of 2 kV, to radiated fields of 10 V/m and to electrostatic discharge of 6 kV on contact and 8 kV in air, with Class B emission. The operating and storage range is -40 to 70 °C. Certifications are CSA and UL listed, with the standards IEC 60947-1, IEC 60947-5-1, IEC 60947-5-4, IEC 60947-5-5, UL 508 and CSA C22.2 No 14. No marine approvals are listed for ZBVB4.
Supply and LED behaviour
This is the 24 V red member. With only one supply value, the same panel supply that feeds relays and PLC inputs at 24 V can feed the lamp directly, and the datasheet records a current consumption of 18 mA, which is the only block among the ZBV references covered here that lists a consumption figure.
The datasheet limits for ZBVB4 are 19.2 to 30 V DC and 21.6 to 26.4 V AC, with a steady signal and an integral LED, which means that the lamp is not replaceable inside the block. The service life is given as 100,000 h at rated voltage and 25 °C, and the surge withstand is 1 kV. The light block is supplied directly, with no series resistor needed.
Mounting, terminals and wiring
The block fixes to the back of the head at the front-mounting position. The datasheet gives screw clamp terminals for up to two 1.5 mm² conductors with cable ends, or one conductor from 0.22 mm² without ends, with a tightening torque of 0.8 to 1.2 N.m. The weight is 0.017 kg, and the block is sold in packs of 5.
The IP20 rating is that of the block behind the panel, so water and dust protection comes from the head and from the panel gasket. Observe polarity on a DC supply, then switch on and confirm that the lamp is dark when the circuit is off and lit when it is on.

About brand
Schneider Electric is the French group for energy management and industrial automation: low and medium voltage switchgear and circuit breakers, motor control, drives, PLCs, power monitoring, UPS systems and building management. Its history goes back to 1836, when the brothers Adolphe and Eugène Schneider took over the iron and steel works at Le Creusot in Burgundy. Over the 20th century the company left steel and heavy engineering and became an electrical group through acquisitions such as Merlin Gerin, Télémécanique, Square D and Modicon. Its head office is in Rueil-Malmaison near Paris, and its shares are listed on Euronext Paris.

- 1975: First investment in Merlin Gerin, a French maker of electrical distribution equipment.
- 1988–1992: Télémécanique, Square D (USA) and Merlin Gerin join the group, making it an electrical specialist.
- 1997: Modicon, the company behind the first programmable logic controller, joins the group.
- 1999: The group takes the name Schneider Electric.

Choosing Schneider Electric breakers and motor control
Circuit breakers are chosen by current and breaking capacity. Acti9 miniature circuit breakers (iC60, C120) protect final circuits up to 125 A. ComPacT NSX molded case breakers cover about 16 to 630 A, and the letter after the frame size sets the breaking capacity: B, F, N, H, S, L from lowest to highest. MasterPacT air circuit breakers are used as main incomers on large switchboards. For motors, a TeSys contactor with an LRD overload relay or a GV2 motor circuit breaker suits direct starting, an Altistart soft starter reduces starting current, and an Altivar drive controls speed. The breaking capacity must always be at least the prospective short-circuit current at the point of installation.
Where Schneider Electric products are used
In Oman and the GCC, Schneider Electric equipment is found in main and sub-main switchboards of commercial and residential buildings, motor control centres in water, oil and gas and industrial plants, substations protected by Sepam and Easergy relays, data centres powered by Galaxy and APC UPS systems, and buildings controlled by EcoStruxure Building Operation.
APC by Schneider Electric: UPS and critical power
Since 2007, APC has been part of Schneider Electric and is now its product brand for uninterruptible power supplies, replacement batteries, battery packs, network management cards and rack power distribution. Our APC catalogue covers Smart-UPS line-interactive and on-line models, Easy UPS On-Line, the modular Symmetra LX, RM and PX ranges, Silcon three-phase systems and their spare part kits, and the RBC cartridges that keep them running. Schneider Electric breakers, drives and PLCs can be quoted together with APC UPS systems in one request.
