Schneider Electric LV429840 ComPact NSX100N MCCB 100A 3P 50 kA

The Schneider Electric LV429840 is a thermal-magnetic molded case circuit breaker from the renowned ComPact NSX MCCB range, a genuine OEM component built for the demanding industrial conditions of Saudi Arabia. Rated at a series of NSX100N with a rated current of 100A, the LV429840 is manufactured to the IEC 60947-2 standard and is fully compatible with the distribution boards, motor control centres and automation panels used across the Kingdom's oil & gas, petrochemical, water and power sectors. Specified by consultants and panel builders on ARAMCO, SABIC, MAADEN and NEOM projects, this device combines proven Schneider Electric reliability with the long service life and electrical safety that keep critical Saudi installations running through extreme heat, dust and coastal humidity. Razz Middle East stocks the LV429840 for immediate supply across Dammam, Riyadh and Jeddah.

Technical Overview

The ComPact NSX MCCB platform is engineered around Schneider Electric's decades of switchgear and motor control expertise, and the LV429840 inherits that pedigree. As a thermal-magnetic molded case circuit breaker, it delivers a series of NSX100N while maintaining tight tolerances across temperature and voltage variation — a key differentiator from lower-cost imports that derate sharply above 40 degrees Celsius. Internally the device uses high-grade silver-alloy or sintered contact materials, glass-reinforced thermoplastic housings and precision-calibrated trip or coil mechanisms, ensuring repeatable operation over hundreds of thousands of cycles. Construction to IEC 60947-2 means the LV429840 carries the international type-test approvals (CE, and UL/CSA on applicable references) that Saudi Aramco SAES and SASO conformity require. It integrates natively into the Schneider EcoStruxure digital architecture, allowing the ComPact NSX MCCB range to share auxiliaries, accessories and communication options with other Schneider devices in the same panel. This interoperability simplifies spares holding and lets engineers standardise on a single trusted brand across an entire facility, reducing both engineering risk and lifecycle cost.

Performance & Specifications

Headline performance figures for the LV429840 include a series of NSX100N, rated current of 100A and poles of 3P. These are catalogue-verified values measured to the IEC 60947-2 test regime, not nominal marketing claims, so designers can size protection and coordination studies with confidence. The LV429840 holds its rated performance across the full ambient range encountered on Saudi sites — from air-conditioned control rooms to sun-exposed field enclosures where internal temperatures climb well beyond 50 degrees Celsius. Robust IP-rated construction resists the fine airborne sand of the interior and the salt-laden humidity of the Eastern Province coastline, while generous terminal capacity speeds installation and reduces the risk of loose-connection hot spots. Full technical specifications, including the complete dimensional and accessory data, are listed in the specifications section below.

Applications in Saudi Arabia

The LV429840 is deployed across virtually every heavy industry in the Kingdom. In the oil & gas sector, Saudi Aramco specifies ComPact NSX MCCB devices in the motor control centres and switchrooms of its upstream gas plants and refineries around Dammam, Abqaiq and the Eastern Province, where reliable motor switching and protection are safety-critical. At SABIC and Sadara petrochemical complexes in Jubail, the device controls and protects pump, compressor and conveyor drives running continuously in corrosive process environments. MAADEN's phosphate and aluminium operations at Ras Al Khair rely on the same range for mining and smelter auxiliaries, while SWCC and Marafiq desalination plants use it across high-availability pumping stations. The giga-projects of Vision 2030 — NEOM, Oxagon and the Red Sea developments — are standardising on Schneider Electric switchgear for new utility and building infrastructure. Cement plants near Riyadh and Yanbu, Saudi Electricity Company distribution substations, and water-treatment works nationwide all represent established applications. Panel builders and contractors in Riyadh, Jeddah and Dammam choose the LV429840 for both new-build and retrofit work because of its proven track record and immediate local availability.
