T7H-1600 — ABB SACE Tmax T7 High-Performance MCCB
The ABB SACE Tmax T7 is the highest-performance molded case circuit breaker in ABB's Tmax family, designed for main distribution and incomer protection in demanding low-voltage applications up to 1600 A and breaking capacities reaching 150 kA at 415 V AC. Built to IEC 60947-2 and tested under the most rigorous short-circuit conditions, the T7 is available in fixed and plug-in (withdrawable) versions with three-pole and four-pole configurations, making it equally suited as a fixed incomer, a section switch, or a tie breaker in double-busbar switchboards. The Ekip electronic trip unit family — from the basic Ekip LSI to the advanced Ekip Hi-Touch with integrated power metering and harmonic analysis — transforms the T7 from a simple overcurrent device into a smart protection and monitoring asset capable of communicating over Modbus, PROFIBUS, or Ekip Link.
What distinguishes the T7 technically from standard MCCBs in its current class is the combination of 150 kA breaking capacity, zone selective interlocking (ZSI) via hardware ZSI terminals, and the availability of a withdrawable plug-in version that allows hot extraction of the breaker from the panel without de-energizing the busbar. The ZSI function coordinates tripping between upstream and downstream Ekip-equipped breakers to clear faults at the lowest possible level within 10–12 ms, limiting arc energy and preventing cascading outages in multi-level distribution systems — a critical capability in Saudi Arabia's data centers and hospital critical power systems where selectivity planning is subject to IEC 60909 fault level analysis. The integrated Ekip energy meter, Class 1 accuracy, eliminates the need for separate metering CT and panel instruments on main incomers.
The Tmax T7 Saudi Arabia is the standard main incomer MCCB in medium to large LV switchboards across the Kingdom's commercial, industrial, and utility sectors. Saudi Aramco substation LV main boards, SABIC plant distribution boards, SEC utility grid connection boards, and main incomers in King Fahd Medical City and King Faisal Specialist Hospital power distribution systems all use the T7 in its fixed and withdrawable configurations. Telecom operator data centres in Riyadh's tech corridor specify T7 withdrawable breakers in their A+B parallel UPS distribution systems to maintain hot standby capability without interrupting IT load. Vision 2030 infrastructure projects including NEOM's distribution substations and Qiddiya's utility infrastructure include T7 main incomers in their SLD specifications.
Razz Middle East maintains in-kingdom stock of T7 in key ratings (630 A, 800 A, 1000 A, 1250 A, 1600 A) in both fixed and plug-in versions with Ekip LSI, LSIG, and Hi-Touch trip units. We provide full switchboard coordination studies, arc flash hazard analysis, and Ekip configuration services for new and retrofit projects across Saudi Arabia, with delivery to all major industrial and commercial centres.

Key Features & Benefits
- Breaking capacity up to 150 kA at 415 V AC in a molded case format provides the highest short-circuit interrupting performance available without moving to a full air circuit breaker, covering the fault levels at ARAMCO and SABIC main distribution boards.
- Zone Selective Interlocking (ZSI) hardware terminals on Ekip trip units coordinate trip timing between cascaded breakers, clearing faults at the lowest distribution level within 10–12 ms to limit arc energy and maintain upstream supply continuity.
- Plug-in withdrawable version allows live extraction and replacement of the breaker mechanism from its cradle without de-energizing the busbar — essential for hospitals, data centers, and critical industrial facilities that cannot accept total supply interruption for maintenance.
- Ekip Hi-Touch trip unit integrates Class 1 energy meter measuring V, I, P, Q, S, PF, and harmonics up to the 31st order, eliminating separate metering instruments and CT wiring for energy management on main incomers.
- Ekip Link communication module provides Modbus RTU/TCP and PROFIBUS connectivity, enabling the T7 to report protection events, metering data, and breaker status to SCADA systems and building energy management platforms.
- Ekip LSIG trip unit provides ground fault (G) protection in addition to LSIG overcurrent functions, satisfying NEC 230.95 and IEC 60364 earth fault protection requirements for main service equipment at commercial and industrial facilities.
- Four-pole configuration with fully rated neutral pole covers TN-S and TN-C-S distribution systems, required by Saudi Aramco's SAES-P-100 and IEC 60364-4-41 for earth fault loop impedance compliance at LV distribution boards.
Industrial Applications in Saudi Arabia
- Main incomer protection for LV switchboards at Saudi Aramco upstream and downstream facilities, where the T7's 150 kA breaking capacity covers the fault levels at busbars fed directly from 11 kV/LV distribution transformers.
- Hospital main distribution incomer and essential services bus tie breakers at King Fahd Medical City, King Faisal Specialist Hospital, and Vision 2030 healthcare infrastructure projects, where plug-in withdrawable T7s enable live maintenance without interrupting critical loads.
- Data centre A+B parallel UPS distribution main breakers for telecom and hyperscale operators in Riyadh, where ZSI coordination and withdrawable format maintain continuous IT power availability during planned and reactive maintenance.
- SABIC petrochemical plant LV main switchboard incomers and bus-coupler breakers at Jubail Industrial City, where the T7's 150 kA performance covers the available fault current at secondary distribution level.
- SEC utility grid connection LV main breakers for commercial and industrial customers, where Ekip metering provides the billing-grade energy measurement data required by SEC for tariff reconciliation.
- Airport and railway infrastructure main distribution boards for Riyadh Metro Phase 2 and King Abdulaziz International Airport expansion, where high breaking capacity and selective protection coordination are mandatory under NFPA 70 and IEC 60364.
- Industrial MCC main incomers and bus-section switches at water treatment plants and desalination facilities, where the T7 plug-in version facilitates scheduled MCCB testing and replacement during planned maintenance outages.
