Delixi CDM1 3P 100A Moulded Case Circuit Breaker

The Delixi CDM1-100M/3300 is a 3-pole 100A moulded case circuit breaker (MCCB) with a 70 kA rated short-circuit breaking capacity at 400 V AC, designed to IEC 60947-2 and suited for use as a main incomer, bus section, or feeder device in low-voltage distribution switchboards serving commercial and industrial facilities across Saudi Arabia. The CDM1 series is Delixi's direct answer to the Schneider Electric NSX and Compact NS product families: it occupies the same physical footprint, supports the same accessory ecosystem (shunt trip, under-voltage release, auxiliary contacts, motor operator), and delivers comparable protection coordination performance at a materially lower cost — a combination that has made it the leading value-alternative MCCB in the Saudi budget panel market over the past decade.

The 70 kA breaking capacity of the CDM1-100M/3300 places it well beyond the fault level demand of most commercial and light industrial LV panels in Saudi Arabia. A typical 11 kV/400 V, 630 kVA SEC distribution transformer presents a prospective fault current of approximately 22–24 kA at the 400 V terminals; even allowing for the conservative busbar impedance assumptions used by SEC-registered panel builders, the 70 kA rating provides a comfortable margin that eliminates the need for current-limiting fuses upstream of the MCCB in most standard applications. This margin is particularly valuable in industrial parks such as Jubail and Yanbu, where transformer capacity is often larger and fault levels correspondingly higher than in commercial districts.

For Saudi Arabia's ARAMCO and downstream petrochemical contractor community, the CDM1-100M/3300 is attractive as a value-line option in non-critical utility and facility support switchboards — motor control centres for HVAC, lighting panels, workshop distribution boards, and site infrastructure panels — where the contractor's approved vendor list permits the use of IEC 60947-2 compliant MCCBs from qualified manufacturers. Delixi's ISO 9001 manufacturing certification and the availability of third-party IEC test reports support the technical submission process. The CDM1 accessories (shunt trip for remote tripping, undervoltage release for generator changeover schemes, and motor operator for remote switching) are available through Razz Middle East and match the same accessories used on Schneider Compact NS, simplifying upgrades and mixed-fleet maintenance for panel builders already familiar with the NS ecosystem.

Razz Middle East distributes the Delixi CDM1 series with full accessory support across Saudi Arabia. Our technical team can assist with protection coordination studies, advise on setting the adjustable thermal and magnetic trip thresholds of the CDM1-100M/3300 to coordinate with upstream utility protection and downstream MCBs, and supply complete panel material lists for budget LV distribution panel builds in Riyadh, Jeddah, Dammam, Jubail, Yanbu, and Makkah. We stock CDM1 accessories — shunt trips, UVRs, auxiliary contacts, and rotary handles — and can provide combined supply of CDM1 MCCBs with Delixi CD10 contactors and JR28 thermal overload relays for complete motor control centre panel kits.
