ABB 1SDA038323R1 ABB Tmax Moulded-Case Circuit Breakers

Razz Middle East supplies ABB Tmax moulded-case circuit breakers and their trip units, terminals and accessories in Saudi Arabia, sourced to order against the 1SDA reference. Tmax covers the protection layer between an incoming board and the feeders below it — distribution, motor and generator protection, and isolation duty. Breakers are quoted per part number and delivered duty-paid, with a typical lead time of three weeks.

About ABB Tmax Moulded-Case Circuit Breakers

Tmax is built as a set of frames rather than a list of individual breakers. The current Tmax XT range runs from the compact XT1 up through XT2, XT3, XT4 and the larger XT5, XT6 and XT7 frames, while the earlier Tmax T range (T1 to T7) is still widely installed; together they span rated currents from the low tens of amps up to 1,600 A, in three- and four-pole versions. Each frame accepts more than one trip unit. Thermomagnetic units (TMD, TMA) give a fixed or adjustable thermal element with a magnetic instantaneous trip. Electronic Ekip units replace that with adjustable long-time, short-time, instantaneous and, on the earthed variants, earth-fault settings, and the higher Ekip versions add measurement and communication so the breaker reports current and energy to the switchboard.

The rest of the code covers the mechanical build: fixed, plug-in or withdrawable; front, rear or spreader terminals; and the accessories that mount inside the same envelope — shunt trips, undervoltage releases, auxiliary and trip-alarm contacts, motor operators, rotary and door-mounted handles, interlocks and terminal shrouds. A 1SDA number identifies exactly one of those combinations.

ABB Tmax Moulded-Case Circuit Breakers in Saudi Arabia

Tmax breakers fill the distribution boards and motor control centres of most large Saudi industrial sites. In Jubail and Yanbu they protect feeders inside petrochemical MCCs and substation boards; on Aramco and Ma'aden sites they appear in generator and transformer secondary protection where the electronic trip units are used to grade against upstream devices. Desalination and water-treatment plants use them on pump feeders, where the adjustable short-time delay matters because starting current has to pass without a nuisance trip. Cement plants and large commercial projects — hospitals, malls, hotel and mixed-use blocks along the Red Sea coast — use the smaller frames throughout their sub-distribution. Everything runs on a 380/400 V, 60 Hz SEC supply, prospective fault levels near a large substation drive the breaking-capacity class you need, ambient temperature in a switchroom that has lost its cooling drives derating, and imported switchgear is subject to SASO conformity.

Ordering and lead time

Give the complete 1SDA number from the breaker label or the switchboard schedule. Numbers in this family look alike — 1SDA067071R1 and 1SDA066652R1 are different frames with different trip units — and the code, not the frame marking, carries the pole count, the rated current, the breaking-capacity class, the trip unit and the terminal type. If you are replacing a breaker in service, send a photograph of the front label and tell us whether it is fixed, plug-in or withdrawable, because a plug-in breaker ordered as a fixed one will not fit the existing base. For a new board, give the rated current, pole count, prospective short-circuit current at that point and any accessories the schematic calls for, and we will build the reference. Trip units and accessories are ordered separately from the breaker body. Sourced to order, typical lead time three weeks, delivered duty-paid.
