IZMX16N4-A12F — Eaton IZMX16 Air Circuit Breaker
The Eaton IZMX16 Air Circuit Breaker is a premium withdrawable four-pole ACB engineered for main incoming, bus-tie, and feeder protection applications in low-voltage main distribution switchgear operating at up to 1000 V AC. With a current rating range spanning 630 A to 1600 A and a breaking capacity of 100 kA at 415 V AC, the IZMX16N4-A12F meets the exacting fault-clearing requirements of Saudi Arabia's largest industrial and utility switchgear installations — from ARAMCO and SABIC main LV distribution boards to SEC-connected industrial substation main incomers. The breaker is built to IEC 60947-2 and complies with the Gulf electrical safety standards referenced in SEC distribution specifications, making it straightforward to obtain SEC engineer acceptance on energy utility interface projects across the Kingdom.
The IZMX16 integrates Eaton's intelligent EN4 electronic trip unit, which provides adjustable long-time, short-time, and instantaneous protection functions with independently settable time-current characteristics for each zone. The EN4 trip unit incorporates an LCD operator panel displaying measured RMS current per phase, neutral, and ground fault values in real time, enabling panel operators to read load conditions without additional instrumentation. Zone Selective Interlocking (ZSI) communication between upstream and downstream ACBs reduces the arc-energy released during downstream faults by confining the tripping to the nearest upstream device — a critical safety benefit in high-fault-level main distribution panels where bus fault energy can otherwise cause catastrophic switchgear damage and operator injury.
In Saudi Arabia, the IZMX16 is specified for main LV incomer panels in ARAMCO upstream plant substations in the Eastern Province, SABIC petrochemical facility main LV distribution in Jubail Industrial City, NEOM utility infrastructure main switchgear where IEC 60947-2 compliance and intelligent trip unit communication are mandated, and SEC-registered industrial consumer LV switchgear requiring utility-grade fault protection. The withdrawable drawout design allows the breaker to be racked out for maintenance or tested with the panel live, a critical operational advantage in process plants where continuous production uptime is the primary constraint. The integrated motor operating mechanism and remote racking capability allow operation from outside the panel arc-flash exclusion zone, fully aligning with NFPA 70E and IEC 60079-14 arc-flash safety requirements increasingly enforced on ARAMCO and SABIC facilities.

Key Features & Benefits
- EN4 intelligent electronic trip unit provides fully adjustable long-time, short-time, and instantaneous protection with real-time RMS current display per phase on an integrated LCD panel — eliminating the need for separate ammeters.
- Zone Selective Interlocking (ZSI) confines fault clearing to the nearest upstream device, dramatically reducing arc energy in downstream faults and protecting main switchgear bus bars from catastrophic damage.
- Withdrawable drawout design allows the breaker to be racked out for maintenance or testing with the panel energised, enabling zero-downtime maintenance in continuous-process Saudi industrial plants.
- Motor-operated mechanism with remote racking capability allows closing, opening, and racking from outside the arc-flash exclusion zone — fully compliant with NFPA 70E and ARAMCO electrical safety procedures.
- Breaking capacity of 100 kA at 415 V AC handles the highest prospective fault currents at ARAMCO Eastern Province and SABIC Jubail LV bus bars without requiring current-limiting fuses.
- IEC 60947-2 type-tested with full test documentation accepted by SEC engineers for utility-interface LV switchgear approval across Saudi Arabia.
Industrial Applications in Saudi Arabia
- Main LV incoming breakers at ARAMCO upstream and downstream plant substations in the Eastern Province, where 100 kA breaking capacity and withdrawable design are standard facility specifications.
- Bus-tie breakers in SABIC petrochemical plant main LV switchgear in Jubail Industrial City, where ZSI communication between incomers and bus-tie eliminates unnecessary load shedding during single-source faults.
- Main distribution panel incomers for NEOM utility infrastructure projects, where IEC 60947-2 compliance, intelligent trip unit communication, and arc-flash safety features are mandated by the master design specification.
- SEC-registered industrial consumer LV main incomer panels where utility acceptance requires IEC 60947-2 compliance documentation and adjustable overcurrent protection settings.
- Hospital main LV switchgear in Ministry of Health facilities across the Kingdom, where withdrawable design and motor operation allow live maintenance without interrupting ICU and operating theatre supply.
- Data centre main LV distribution panels in SDAIA national data centre facilities, where the EN4 trip unit's Modbus communication provides real-time current data to the DCIM platform.
