Legrand CTX3 Industrial Contactor 9–800A

The Legrand CTX3 Industrial Contactor is a comprehensive range of IEC 60947-4-1 rated AC and DC contactors spanning the full industrial application spectrum from 9 A motor control on small pumps and fans to 800 A main power switching on large motor starters and generator changeover panels. The 416810 model covers the 40 A three-pole AC-3 contactor — the most commonly used rating in industrial motor control centres across the GCC — engineered for continuous duty at 45 °C ambient without derating, making it well suited to Saudi Arabia's demanding climate. The CTX3's silver-cadmium oxide (AgCdO) contact material provides the combination of low contact resistance, high arc erosion resistance, and good anti-welding properties that IEC 60947-4-1 requires for Category AC-3 (squirrel cage motor switching), AC-4 (reversing and plugging duty), and AC-1 (resistive loads) applications. The standard auxiliary contact block supports up to four early-make or early-break contacts that mount directly to the contactor body without tools, providing the control circuit interlocking and status signalling functions required in motor control panel designs.

The CTX3 design prioritises in-panel space efficiency: the 40 A frame width of 45 mm — 25% narrower than the previous generation — allows more contactors to fit within a given DIN rail length in compact motor control centres (MCCs) where panel real estate is at a premium. The coil is available in a universal voltage version (24–240 V AC/DC) that eliminates the need to specify separate coil voltage variants for AC and DC control circuits on the same project, reducing procurement complexity and eliminating the risk of ordering wrong-coil-voltage units on large multi-panel projects. The coil dissipation of 2.8 W in held state is among the lowest in the 40 A class, directly reducing panel internal heat generation and potentially allowing a smaller panel cooling unit on thermally marginal MCC designs. The CTX3's rated mechanical life of 30 million operations and electrical life of 1.5 million operations in AC-3 category exceed the service life expectations of standard industrial equipment, providing confidence in long-term reliability at petrochemical and process plant facilities in Saudi Arabia.

Industrial electrical switchgear and motor control are core to every manufacturing, processing, and infrastructure project in Saudi Arabia, from the 2400 VAC motor starters on ARAMCO's upstream pump stations to the small fan motor contactors in HVAC switchboards serving Riyadh's commercial towers. The CTX3 range is specified by Saudi panel builders under Legrand-approved system designs for motor control centres that carry the Saudi Standards, Metrology and Quality Organization (SASO) panel certification mark, which is required before panels can be energised at SEC-connected facilities. The CTX3 is equally at home in utility-grade switchboards at SWCC desalination plants, in cement plant MCC panels at Saudi Cement and Yanbu Cement facilities, and in water treatment plant starter panels at National Water Company projects across the Kingdom — applications where the 45 °C continuous ambient rating and the IP2X finger-safe contact design provide the reliability and safety that facility engineers require.

Razz Middle East stocks the Legrand CTX3 range from 9 A to 150 A in both fixed coil voltage and universal coil voltage variants, with matching overload relays, auxiliary contact blocks, mechanical interlock bridges, and mounting accessories. We hold certified panel builder approval from Legrand Saudi Arabia and can supply CTX3 with SASO documentation packages for panel certification submissions. Our engineers advise on contactor selection for specific motor applications including soft-starter bypass, inverter bypass, and capacitor bank switching duties where standard AC-3 contactors require derating.
