E2.2B-1600-W — ABB Emax 2 Withdrawable Air Circuit Breaker
The ABB SACE Emax 2 withdrawable air circuit breaker (ACB) is the industry benchmark for high-current LV protection in critical and industrial power distribution, covering rated currents from 800 A to 6300 A with breaking capacities up to 150 kA at 415 V in accordance with IEC 60947-2. The withdrawable cradle mechanism allows the breaker to be moved to Connected, Test, and Disconnected positions with the main busbars fully energised, meaning maintenance and replacement can be completed without removing supply to healthy circuits. Every position can be individually padlocked in compliance with LOTO (lock-out/tag-out) procedures required on Saudi Aramco and SABIC sites.
The integrated Ekip electronic trip unit upgrades the Emax 2 far beyond a simple protection device. Ekip Hi-Touch and Ekip Touch variants provide L–S–I–G–R protection functions, a built-in Class 1 energy meter, power quality monitoring, and Ekip Link communications over Modbus RTU, PROFIBUS DP, or IEC 61850 GOOSE messaging for digital substation integration. Zone selective interlocking (ZSI) coordinates upstream and downstream Emax 2 breakers to minimise fault clearance time while maintaining selective discrimination, a critical requirement for the tiered protection hierarchies specified in SEC HV/LV standards and large industrial main distribution boards.
In Saudi Arabia's Vision 2030 infrastructure programme — mega-projects including NEOM, Red Sea Project, Qiddiya, and the expansion of King Salman Energy Park (SPARK) — the Emax 2 withdrawable is the ACB of choice for main LV switchboards where uptime requirements prohibit total shutdown for maintenance. The Saudi Electricity Company (SEC), MARAFIQ, and SWCC specify withdrawable ACBs for all critical incomer positions in new SEC-approved switchgear. Saudi data centre operators following Uptime Institute Tier III/IV standards mandate withdrawable ACBs at all main incomer and distribution positions to enable live-panel maintenance.
Razz Middle East is an authorised ABB distributor supplying Emax 2 withdrawable breakers with full Ekip trip unit configurations, communication modules, and accessories from stock in Riyadh and Jeddah. Our engineers provide IEC 60947-2 type test documentation, factory acceptance test (FAT) certification, and on-site commissioning including primary injection tests and LOTO procedure verification for Saudi Aramco and SABIC contractor approval packages.

Key Features & Benefits
- Withdrawable cradle with three padlockable positions (Connected, Test, Disconnected) enabling full LOTO compliance for live-panel maintenance required on Saudi Aramco, SABIC, and SEC sites — eliminating the need to de-energise healthy circuits during ACB maintenance or replacement.
- Ekip Hi-Touch electronic trip unit with LSIG+G protection functions, including selective ground fault detection, adjustable short-time delay (STD) up to 500 ms with I²t limiting, and instantaneous override — all configurable via the integral graphical display without secondary injection equipment.
- Integrated Class 1 energy meter (IEC 62053-21) measuring V, A, kW, kVAR, kVA, kWh, power factor, and THD, eliminating the need for a separate multifunction meter at the main incomer position and reducing switchboard cost and complexity.
- Ekip Link communication module supporting Modbus RTU, PROFIBUS DP, CANopen, and IEC 61850 GOOSE messaging for native integration with ABB Ability digital substation SCADA and with Saudi Electricity Company (SEC) SCADA over standard protocols.
- Zone Selective Interlocking (ZSI) between Emax 2 breakers reduces fault clearance time from the full STD setting to instantaneous when downstream ZSI signals confirm a fault is local — providing both fast fault clearance and full selectivity for a multi-tier LV distribution scheme.
- Breaking capacity certified to 150 kA at 415 V under IEC 60947-2 with full Type Test documentation available for Saudi Electricity Company (SEC) switchgear approval submissions and Aramco SAES-P-100 contractor qualification packages.
- Compatible with full Emax 2 accessory range including motor operators, shunt trips, undervoltage releases, auxiliary contact blocks, and anti-pumping relays, allowing complete functional specification from a single manufacturer with single-source traceability.
Industrial Applications in Saudi Arabia
- Main LV incomer switchboards in Saudi Electricity Company (SEC) approved primary and secondary substations, where withdrawable ACBs are mandated for all incomer positions rated above 800 A to enable live maintenance without customer supply interruption.
- Data centre main distribution frames (MDF) at hyperscale and co-location facilities being built at NEOM and Riyadh, where Uptime Institute Tier III concurrently maintainable requirements prohibit fixed-mount ACBs at any position in the critical power path.
- Hospital and healthcare facility main and emergency switchboards at Ministry of Health (MoH) and private hospital projects, where JCI accreditation and NFPA 99 healthcare facilities standards require withdrawal-capable ACBs on all generator-bus-tie incomer positions.
- Industrial main distribution boards at SABIC petrochemical complexes in Jubail Industrial City and Yanbu Industrial City, where SABIC SESG electrical engineering standards specify withdrawable ACBs rated to the prospective fault level of the 11 kV supply transformer.
- Offshore oil and gas platform main switchboards at Saudi Aramco offshore field developments, where SAES-P-100 specifies IEC 60947-2 ACBs with withdrawable mounting and integrated protection for all main and bus-tie positions in safety-critical areas.
- Uptime-critical telecom exchange and BTS hub power distribution at STC, Zain, and Mobily network infrastructure sites, where withdrawable ACBs are specified for 24/7 operations centres that cannot tolerate planned maintenance shutdowns.
- SEC grid connection switchgear at large solar and wind renewable energy plants under REPDO's National Renewable Energy Programme, where the main incomer ACB must be withdrawable to facilitate commissioning testing with the grid connection de-energised from the generation side only.
