Schneider Electric LV430630 ComPact NSX160F 160 A 36 kA Breaker

LV430630 molded case breaker, 160 A thermal-magnetic, 36 kA at 415 V

The LV430630 is a Schneider Electric product listed in the datasheet as: Circuit breaker, ComPact NSX160F, 36kA/415VAC, TMD trip unit 160A, 3 poles 3d. The LV430630 is a ComPact NSX160F breaker with a TMD trip unit rated 160 A and 36 kA breaking capacity at 415 V. The NSX160 frame is one step larger than the NSX100 frame and is used for larger feeders and motors. Seven Star LLC supplies the LV430630 in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference: NSX160F is the 160 A frame with the F performance class (36 kA at 415 V), and the TMD 160 A trip unit sets the thermal-magnetic protection. As with the LV429630, the datasheet records the reference as discontinued.

Technical specifications of the LV430630

Frame, trip unit and ratings of the LV430630

Network frequency: 50/60 Hz. Rated operational voltage: 690 V AC 50/60 Hz. Utilisation categories: Category A. Trip unit technology: Thermal-magnetic. Breaking capacity: 36 kA 380/415 V AC 50/60 Hz IEC 60947-2; 85 kA 220/240 V AC 50/60 Hz IEC 60947-2; 22 kA 525 V AC 50/60 Hz IEC 60947-2. Mechanical durability: 40000 cycles. Electrical durability: 7500 cycles 690 V In; 15000 cycles 690 V In/2; 20000 cycles 440 V In; 40000 cycles 440 V In/2.

The thermal element is adjustable below the 160 A maximum, so the breaker can be tuned to the cable rating. The magnetic element operates for short circuits; read its trip values from the datasheet and the trip-unit curves.

Replacement context for the LV430630

Because of the discontinued status, confirm the successor with the supplier and check cable lugs, panel cut-outs and accessories. The 100 A sibling LV429630 shares the NSX accessory family, so sites with both can share some accessories, while the larger frame differs in terminal spacing.

Test results and settings should be stored in the maintenance record.

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 LV430630 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 LV430630

• Feeder current and cable rating: 160 A.
• Fault level: 36 kA at 415 V.
• Trip unit type.
• Accessories and handle.
• Panel space for the larger frame.
• Spare or replacement application.

Fitting and routine checks of the LV430630

Tighten lugs to the specified torque with a calibrated tool and use thermography at the first load test to find hot connections. Operate and trip-test regularly.

Record the settings of the dials after each adjustment.

Typical applications of the LV430630 in Oman and the GCC

In Oman and the GCC the 160 A NSX frame is used on main feeders of process buildings, motor control centres and water plants.

Dimensions, environment and approvals of the LV430630

For the LV430630, plan the mounting space from the datasheet: 105 mm (W) x 161 mm (H) x 86 mm (D). The LV430630 weighs 2.2 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 LV430630

• 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 LV430630

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 LV430630, 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 LV430630 and recording settings such as trip ranges or ramp times shortens repair work during a breakdown.
