Delixi CDM1 3P 250A Moulded Case Circuit Breaker

The Delixi CDM1-250M/3300 is a 3-pole 250A moulded case circuit breaker with a 70 kA rated short-circuit breaking capacity at 400 V AC, compliant with IEC 60947-2 and positioned as a cost-effective alternative to Schneider Electric Compact NS250 and similar 250-frame MCCBs used extensively in Saudi Arabia's commercial and industrial LV switchboard market. The 250A frame is the most common incomer rating for distribution boards serving large commercial floor zones, light industrial workshops, data halls, cold store facilities, and process plant ancillary panels — making the CDM1-250M/3300 one of the highest-volume MCCB products in the Saudi LV panel procurement market.

In Saudi Arabia's commercial construction landscape, the 250A MCCB typically appears as: the main incomer to a 200A–250A distribution board serving an entire commercial floor or retail anchor tenant; as a feeder to sub-distribution boards in multi-storey developments; or as the outgoing feeder in a main LV switchboard rated at 1600A–3200A serving multiple 250A circuits. The 70 kA breaking capacity is more than adequate for all of these positions when the board is fed from any standard SEC distribution transformer rated up to 2500 kVA at 11 kV — a transformer size that generates a maximum fault level of approximately 52 kA at its 400 V terminals under the most pessimistic assumptions. The CDM1-250M/3300's adjustable thermal-magnetic trip unit allows the Ir (overload) setting to be set anywhere between 100A and 250A in increments, enabling the same physical breaker to serve multiple design points and reduce the number of MCCB variants held in a panel builder's stock.

The direct dimensional and accessory compatibility of the CDM1-250M/3300 with the Schneider Electric Compact NS250 is a significant commercial advantage for Saudi panel builders who have inherited NS-based panel designs from engineering consultants or who are expanding existing switchrooms that already contain NS MCCBs. Replacement of faulty NS250 units, addition of outgoing feeders in existing MSBs, and construction of new panels based on existing type-approved designs can all be accomplished with CDM1-250M/3300 units without incurring the engineering cost of re-drawing panel layouts or re-testing enclosure assemblies. This compatibility reduces the total installed cost of the panel and shortens the procurement-to-installation timeline — both critical factors on the fast-track construction programmes typical of Vision 2030 projects in Riyadh, Jeddah, Dammam, and the emerging giga-project sites.

Razz Middle East maintains forward inventory of the CDM1-250M/3300 and its full accessory range — including shunt trip coils rated at 24 VDC (for fire alarm panel interface), 110 VAC, and 230 VAC; undervoltage releases for ATS generator changeover schemes; front-mounted rotary handles for panel door operation; and auxiliary contact blocks for PLC/SCADA status monitoring. Our team can support panel builders from RFQ to delivery with material take-off support, technical data sheets in English and Arabic, and IEC 60947-2 test certificates.
