ABB SACE Tmax XT1 Molded Case Circuit Breaker

ABB SACE Tmax XT1 Molded Case Circuit Breaker — Industrial Power Protection for Saudi Arabia

The ABB SACE Tmax XT1 is a compact, high-performance molded case circuit breaker (MCCB) from ABB's industry-leading SACE Tmax range. Rated up to 160A and offering breaking capacities up to 36 kA at 415V AC, the XT1 is the go-to choice for motor control centers (MCCs), main distribution boards (MDBs), and feeder protection in Saudi Arabia's demanding industrial environments.

Deployed extensively across Saudi Aramco upstream facilities, SABIC petrochemical plants, SEC power distribution projects, and the mega-construction sites of Vision 2030 giga-projects, the XT1 delivers the combination of compact footprint, high breaking capacity, and ABB's legendary reliability that procurement teams in KSA demand.

Key Advantages for Saudi Industrial Applications

Compact Size, High Performance: At just 70 mm wide for a 3-pole unit, the XT1 fits more breakers in a standard MCC panel — a significant advantage when panel space is at a premium in offshore platform electrical rooms or compact substation buildings at Saudi Aramco's gas plants.

Wide Current Range: Available from 10A to 160A in a single frame size, the XT1 covers the full range of motor starters and feeder circuits in a typical Saudi industrial MCC, reducing spare parts inventory complexity.

Adjustable Thermal-Magnetic Trip Unit (TMD): The TMD trip unit provides adjustable thermal (overload) and fixed magnetic (short-circuit) protection, enabling precise coordination with upstream protection devices in Aramco and SEC distribution schemes.

High Breaking Capacity: The XT1B variant offers a 36 kA Icu at 415V — sufficient for most Saudi LV distribution systems. The XT1N and XT1S variants extend breaking capacity to 50 kA and 70 kA for high-fault-level applications at large petrochemical substations.

Technical Specifications

Applications in Saudi Arabia

Motor Control Centers: Saudi industrial facilities — from SABIC polymer plants in Jubail to Maaden aluminium smelters in Ras Al-Khair — rely on XT1 MCCBs for individual motor feeder protection in their MCCs. The 160A frame suits 55–75 kW motors commonly used in pump and compressor drives.

Main Distribution Boards: Commercial and residential developers in Saudi Vision 2030 projects (NEOM, Qiddiya, Diriyah Gate) specify XT1 MCCBs for incoming protection of tenant distribution boards in multi-tenancy commercial towers.

Renewable Energy: Solar PV string combiner to inverter DC circuits in ACWA Power Saudi projects use XT1 for DC breaking applications (rated up to 250V DC) with appropriate pole configuration.

Oil & Gas Platforms: Offshore platforms operated by Saudi Aramco in the Persian Gulf use XT1 MCCBs rated for marine and offshore applications (supplementary IEC 60092 certification available).

Frequently Asked Questions

Q1: What is the difference between XT1B, XT1N, and XT1S variants? The letter denotes breaking capacity class: B = 36 kA, N = 50 kA, S = 70 kA (all at 415V AC). Choose based on your available fault level at the point of installation — confirmed via short-circuit calculation per IEC 61363 or IEC 60909.

Q2: Can XT1 MCCBs be motorized for remote operation? Yes. ABB offers motor operators (MOE 100...160) and shunt trips (SHT) as accessories that clip onto the XT1 without tools. These enable remote switching from Aramco SCADA or DCS systems.

Q3: What is the ABB XT1 MCCB price in Saudi Arabia? Pricing varies with pole configuration, current rating, and trip unit. Submit your bill of materials to RAZZ via our RFQ system for a competitive quotation with full ABB warranty and COO documentation.

Q4: Are ABB XT1 MCCBs approved for use in Aramco facilities? ABB SACE Tmax products are widely used in Saudi Aramco projects under SAES-P-100 series electrical standards. RAZZ can provide SAES-compliant documentation packages.

Q5: What accessories are available for XT1? Key accessories include: auxiliary contacts (AUX), alarm contacts (AL), undervoltage releases (UVR), shunt trips (SHT), motor operators (MOE), terminal covers, and locking devices. RAZZ stocks full accessory kits.

Q6: What is the lead time for XT1 MCCBs in Saudi Arabia? Standard 3P configurations in common current ratings (63A, 100A, 125A, 160A) are typically in stock for same-week delivery. Motorized or withdrawable variants require 2–4 weeks.

Q7: Can XT1 be used in 60 Hz systems? Yes. The XT1 is rated for both 50 Hz and 60 Hz systems. No derating is required. This makes it suitable for mixed-frequency facilities that interface with US or Canadian equipment operating at 60 Hz.
