ABB SACE Emax 2 Air Circuit Breaker

ABB SACE Emax 2 Air Circuit Breaker — High-Power Protection for Saudi Arabia Industrial & Utility Applications

The ABB SACE Emax 2 is ABB's flagship intelligent air circuit breaker (ACB), designed for high-current protection, metering, and power management in main distribution switchboards, generator paralleling panels, and bus-tie applications. Available in current ratings from 800A to 6300A, the Emax 2 is the definitive choice for Saudi Arabia's large industrial facilities, power-intensive manufacturing complexes, and utility substations handling currents far beyond the range of molded case circuit breakers.

The Emax 2 E2.2N 2000A variant — with its Ekip Touch LSI (Long-time, Short-time, Instantaneous) electronic trip unit — delivers precise overload and short-circuit protection with full programmability, event logging, and digital communication via IEC 61850, Modbus, and PROFIBUS. This makes it the ideal breaker for Saudi Aramco main switchrooms, SABIC power plants, SEC 11kV/LV transformer secondaries, and NEOM's intelligent grid infrastructure.

Key Features for Saudi Industrial Applications

Ekip Touch Trip Unit: The Ekip Touch display provides real-time measurement, fault recording, and diagnostic data directly on the breaker front panel — without requiring a laptop or SCADA connection. Saudi maintenance teams can view fault currents, alarm history, and energy data on-site in English and Arabic.

Zone Selective Interlocking (ZSI): Emax 2 supports ZSI between multiple breakers, allowing upstream breakers to delay tripping when a downstream breaker detects and clears a fault. This minimises arc flash energy and service disruption in Saudi industrial MCCs — a critical safety feature for Aramco's 24/7 production facilities.

Integrated Power Metering: The Ekip Touch unit measures voltage, current, power factor, kWh, kVAh, and power quality parameters — replacing separate power meters in Saudi main distribution panels and generating data for SEC energy billing verification and ISO 50001 energy management audits.

Generator Paralleling: Emax 2 includes built-in sync-check and automatic transfer switching (ATS) logic for emergency generator applications — essential for Saudi hospitals, data centers, and critical facilities requiring seamless transition between SEC grid and standby generation.

Applications in Saudi Arabia

Main LV Switchboards: SABIC YANPET, TASNEE, and CHEMANOL petrochemical facilities in Jubail use Emax 2 as incoming breakers for their main LV switchboards, protecting 11/0.4 kV transformer secondaries handling 1600–4000A.

Data Centers: Hyperscale data centers in Riyadh's tech corridor (STC Cloud, G42 Saudi, Aramco digital) use Emax 2 for main distribution board (MDB) incoming and bus-tie protection, with ZSI enabling fast fault clearance without disrupting live loads.

Saudi Aramco Power Plants: Aramco's captive power plants at Uthmaniyah, Hawiyah, and Haradh gas plants use ACBs for generator and transformer feeder protection in LV switchgear rated to 85 kA fault levels.

SEC Distribution Substations: Saudi Electricity Company's 11/0.4 kV distribution substations in Riyadh, Jeddah, and Dammam use Emax 2 as standard outgoing distribution ACBs for major industrial customers.

Frequently Asked Questions

Q1: What is the ABB Emax 2 price in Saudi Arabia? Emax 2 pricing depends on current rating, number of poles, trip unit configuration, and mounting type. Contact RAZZ for project-specific quotation with full ABB warranty and certification documentation.

Q2: Is the Emax 2 compatible with existing Emax switchgear chassis? No. Emax 2 uses a new chassis design not backward-compatible with the original Emax series. For retrofit projects, consult RAZZ's technical team for switchgear compatibility assessment.

Q3: What communication protocols does Emax 2 support? Emax 2 supports IEC 61850 Ed.2 (GOOSE + MMS), Modbus RTU, Modbus TCP, PROFIBUS DP, DeviceNet, and EtherNet/IP through Ekip communication plug-in modules.

Q4: Can Emax 2 perform arc flash energy limitation? Yes. Through Zone Selective Interlocking (ZSI) and the "Active ZSI" feature, Emax 2 can reduce fault clearing time to < 10 ms for downstream faults, significantly reducing arc flash incident energy at Saudi industrial switchboards.

Q5: What is the delivery time for Emax 2 in Saudi Arabia? Standard Emax 2 configurations in 1600A–3200A ratings are typically available from RAZZ in 4–8 weeks. Custom configurations or very high-current variants (5000A+) require 10–14 weeks from ABB factory.

Q6: Does RAZZ provide switchgear design support? RAZZ offers pre-sales technical support including fault level calculations, breaker sizing, and single-line diagram review for major Saudi industrial switchgear projects.

Q7: Is Emax 2 suitable for 60 Hz operation? Yes, Emax 2 is rated for both 50 Hz and 60 Hz. No derating is required. This makes it suitable for facilities interfacing with international equipment or operating in the eastern Saudi grid zones.
