Schneider Electric LV429630 ComPact NSX100F 100 A 36 kA Breaker

LV429630 molded case breaker, 100 A thermal-magnetic, 36 kA at 415 V

The LV429630 is a Schneider Electric product listed in the datasheet as: Circuit breaker, ComPact NSX100F, 36kA/415VAC, TMD trip unit 100A, 3 poles 3d. The LV429630 is a ComPact NSX100F circuit breaker with a TMD trip unit rated 100 A. It breaks up to 36 kA at 415 V AC and is a three-pole unit. It is a main or feeder device in low-voltage distribution boards. Seven Star LLC supplies the LV429630 in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference: LV429630 combines an NSX100F breaker with a 100 A TMD trip unit; NSX100 is the 100 A frame and F the 36 kA performance level at 415 V. The datasheet marks the reference as discontinued, so it is mainly a replacement part.

Technical specifications of the LV429630

A molded-case breaker protects feeders and large motors against overload and short circuit. The TMD trip unit has a thermal element for overload and a magnetic element for short circuit, and the datasheet lists the breaking capacity values at different voltages.

Lifecycle, successor and accessories for the LV429630

The datasheet marks the LV429630 as discontinued. Newer ranges such as ComPact NSXm or the EasyPact CVS cover similar ratings, but dimensions, accessories and trip units differ; confirm fit before replacing a breaker on a panel.

Accessories such as auxiliary contacts, shunt trips, rotary handles and terminal shields of the older NSX range are not interchangeable with every newer series.

The datasheet downloaded for this page carries lifecycle notices: Discontinued on: Jun 15, 2023. For a plant that already runs this reference that makes the LV429630 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.

Selection checklist for the LV429630

• Load and cable: 100 A.
• Short-circuit level at the busbar: below 36 kA at 415 V.
• Trip unit: TMD thermal-magnetic.
• Number of poles: three.
• Accessories: auxiliary, shunt trip, handle.
• Lifecycle: spare or replacement.

Installation and testing of the LV429630

Fix the breaker on the mounting plate, connect cable with lugs of the specified size, apply the torque and fit terminal shields. Check the thermal setting against the cable rating.

Operate the breaker several times and test the trip using the push-to-trip button during commissioning.

Typical applications of the LV429630 in Oman and the GCC

In Oman and the GCC a 100 A molded-case breaker typically feeds sub-distribution boards, motor control centres and process skids.

Dimensions, environment and approvals of the LV429630

For the LV429630, plan the mounting space from the datasheet: 105 mm (W) x 161 mm (H) x 86 mm (D). The LV429630 weighs 2.05 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: -50 to 85 °C. Relative humidity: 0 to 95 %. Ingress protection: IP40 conforming to IEC 60529. Operating altitude: 0 to 2000 m without derating; 2000 m–5000 m with derating. Standards listed: EN/IEC 60947. Certifications listed for this reference: CCC; EAC; Marine.

Information to send with an RFQ for the LV429630

• Full reference and quantity required
• Existing equipment, panel or rack it must fit
• Supply voltage, load or signal details of the application
• Required delivery location and timing
• Whether a spare, a replacement or a new installation

Site conditions in Oman for the LV429630

Low-voltage switching and protection devices in Oman often sit in motor control centres and outdoor panels where internal temperatures are high for much of the year. When you select the LV429630, check its rated values at your real ambient temperature, as stated in the manufacturer documentation, and confirm the coordination with upstream protection and with the motor or load it serves. Short-circuit levels differ from site to site, so verify the breaking capacity required at the point of installation.

Standardising ratings and coil voltages across a project reduces the number of spare part numbers that need to be stocked. Keeping a small stock of the LV429630 and recording settings such as trip ranges or ramp times shortens repair work during a breakdown.
