CHINT NXM-100 Moulded Case Circuit Breaker
The CHINT NXM-100 Moulded Case Circuit Breaker is a 3-pole and 4-pole MCCB with a frame current of 100 A and an adjustable overload trip setting from 16 A to 100 A, designed to IEC 60947-2 with SASO type approval for Saudi Arabia. The NXM-100 delivers a rated ultimate short-circuit breaking capacity (Icu) of 36 kA and a service short-circuit breaking capacity (Ics) of 25 kA at 415 V, placing it well above the minimum 10 kA typically required on secondary busbars in industrial low-voltage switchgear. Its thermal-magnetic trip unit provides adjustable overload protection via a rotary dial calibrated in amperes, combined with a fixed magnetic instantaneous trip set at approximately 10 × In for short-circuit clearance — a field-proven topology that requires no electronic power supply or battery backup to operate.
The NXM-100 is housed in a compact glass-fibre-reinforced polyester case measuring 105 mm wide for the 3-pole variant, which aligns with standard withdrawable cassette dimensions used in most Saudi-market LV switchgear assemblies. Front-connected, fixed-mounted and plug-in (drawout) versions are available, and the device accepts an extensive range of accessories including auxiliary contacts (1NO+1NE standard, expandable), alarm contacts, motor operators for remote switching, and UVR / shunt trip coils for trip-from-panel-remote applications. The operating handle has a clear O / I / TRIP indication window, and the device can be padlocked in the OFF position for isolation and lockout/tagout (LOTO) compliance — mandatory on ARAMCO, SABIC, and SWCC facilities under their respective permit-to-work systems.
The NXM-100 finds widespread use in Saudi Arabia's industrial and infrastructure sectors wherever a cost-effective yet technically robust MCCB is required below 100 A. Motor feeder protection panels for packaged water treatment plants built by NWC contractors across the Kingdom, fan starter panels in HVAC plant rooms in Riyadh's hospitals and government ministry buildings, and cable feeder protection in sub-stations serving NEOM utility distribution networks are all typical applications. The device's 36 kA Icu rating allows installation closer to the source transformer on 415 V distribution busbars than lower-rated MCCBs, reducing the need for additional upstream series protection. This is particularly valued by EPC contractors working on ARAMCO and SABIC plant expansions in the Eastern Province, where fault levels on 415 V boards can approach or exceed 25 kA.
Razz Middle East maintains stock of the NXM-100 in both 3P and 4P configurations at our Riyadh and Dammam warehouses, with standard accessories — motor operators, shunt trips, and auxiliary contacts — held in buffer stock for rapid dispatch. Pricing is issued in SAR within 4 hours of inquiry, and our engineers provide application engineering support to contractors in Jubail, Yanbu, Jeddah, Mecca, and Medina to ensure correct trip setting selection and upstream co-ordination with existing protection devices.

Key Features & Benefits
- SASO type-approved and IEC 60947-2 certified, meeting Saudi Electricity Company requirements for MCCB installation in LV switchgear and distribution panels across the Kingdom.
- 36 kA ultimate short-circuit breaking capacity (Icu) at 415 V allows installation close to source transformers on Saudi industrial distribution busbars where fault levels approach 25 kA.
- Adjustable overload trip via rotary ampere-calibrated dial from 16 A to 100 A covers a wide range of cable and motor feeder sizes from a single device variant, reducing spares inventory.
- Motor operator accessory enables remote switching and automation integration with PLC-controlled motor control centres, compatible with 24 V DC and 110/220 V AC control supply voltages.
- Padlockable OFF handle provides lockout/tagout (LOTO) compliance for ARAMCO, SABIC, SWCC, and NWC permit-to-work safety systems without additional accessories.
- Compact 105 mm width (3P) fits standard withdrawable cassette dimensions used in Saudi-market LV switchgear assemblies, enabling direct replacement of competitive MCCB brands.
Industrial Applications in Saudi Arabia
- Motor feeder protection in packaged water treatment and desalination plant panels built for NWC and SWCC across the Kingdom, where the 36 kA Icu rating handles fault levels on 415 V supply busbars.
- Cable feeder protection in sub-distribution switchboards at ARAMCO residential cities and industrial facilities in the Eastern Province, replacing higher-cost European MCCBs in non-critical circuits.
- Fan starter panels for central HVAC plant rooms in hospitals, universities, and government ministry buildings in Riyadh and Jeddah under Vision 2030 social-infrastructure projects.
- Incomer protection for utility distribution panels in NEOM utility networks and Red Sea Project infrastructure, where 36 kA breaking capacity meets short-circuit duty on 11/0.415 kV transformer LV terminals.
- LV switchgear feeder protection in SABIC and SADAF petrochemical contractor facilities in Jubail and Yanbu, where motor feeders are concentrated in multi-section motor control centres.
- Emergency generator sub-distribution panel protection in commercial and industrial facilities across Dammam and Al Khobar, where reliable overcurrent protection on generator-fed busbars is essential.
