ABB TMax XT2H 160 3P MCCB 1SDA068165R1 (ABB) – New & Original in Stock

ABB TMax XT2H 160 Breaking Part 1SDA068165R1 | Reliable Automation Component

Field Application & Operational Analysis

From the perspective of a Site Reliability Engineer managing mission-critical electrical infrastructure, the ABB 1SDA068165R1 stands as a cornerstone component for sustaining system availability in high-demand industrial environments. The 1SDA068165R1 — the breaking part of the TMax XT2H 160 frame — delivers deterministic overcurrent and short-circuit isolation across 690V AC and 500V DC networks up to 160A, directly reducing unplanned downtime risk in process-critical distribution panels. Its role in process optimization is not incidental; it is architecturally embedded into selective coordination schemes that ensure only the faulted segment trips, preserving upstream continuity.

Operational durability under adverse conditions is where the 1SDA068165R1 distinguishes itself from commodity alternatives. Rated for ambient temperatures spanning -25°C to +70°C, this breaking unit maintains calibrated trip response even in foundry floors, offshore platforms, and outdoor switchgear enclosures subject to thermal cycling and vibration. During installation, engineers should verify conductor sizing (16mm² to 95mm² Cu/Al) and confirm front-terminal torque specifications per IEC 60947-2 to prevent contact resistance buildup — a common root cause of nuisance tripping in high-cycle automation environments.

As a strategic spare-parts asset, maintaining the 1SDA068165R1 in inventory is a recognized best practice for facilities operating TMax XT-based motor control centers, UPS distribution boards, and renewable energy switchgear. With ABB progressively transitioning legacy product lines, securing original factory stock of this breaking part ensures seamless integration without re-engineering downstream protection coordination.

Maintenance & Performance Benchmarks

The 1SDA068165R1 is architected to adapt across diverse industrial network scales — from compact 160A sub-distribution boards in light manufacturing to multi-tier selective coordination schemes in large petrochemical complexes. In small-to-medium installations, the fixed thermal-magnetic (TMA) trip unit configuration provides cost-effective, maintenance-free protection with factory-set curves. For larger, more complex architectures, the Ekip electronic trip unit variant enables programmable I²t curves, zone-selective interlocking (ZSI), and real-time communication via Modbus or PROFIBUS — transforming this I/O module-class component into an active node within the plant’s Automation Components network.

Benchmark data from field deployments confirms that the XT2H 160 frame maintains ±5% trip accuracy across its full thermal range, outperforming generic MCCB alternatives in high-ambient-temperature environments. Maintenance cycles are extended through arc chute geometry optimized for rapid arc extinction, reducing contact erosion per operation. For facilities pursuing Operational Excellence, integrating this breaking part into a predictive maintenance program — tracking operation counts via motor operator feedback — enables condition-based replacement before end-of-life, eliminating unplanned outages.

Comprehensive Data Sheet

Professional Logistics & Sourcing Excellence

Every unit of the ABB 1SDA068165R1 dispatched from our inventory is supplied in Original Factory Packaging, complete with ABB documentation, factory test certificates, and tamper-evident seals — ensuring full traceability from production line to installation site. For urgent plant maintenance scenarios, same-day dispatch is available for in-stock units (order confirmation before 14:00 local time), with express courier options covering major industrial hubs across Europe, Asia-Pacific, the Americas, and the Middle East within 3-7 business days.

As ABB continues to evolve its TMax product portfolio, the 1SDA068165R1 is increasingly classified as an End-of-Life (EOL) / Legacy Module in certain markets. Our global sourcing network maintains verified stock of original, non-counterfeit units specifically to support facilities that cannot undertake full switchgear replacement programs. All inventory undergoes incoming inspection against ABB’s published dimensional and electrical specifications before dispatch — a critical quality gate for mission-critical applications where counterfeit components represent an unacceptable operational risk.

Engineering Support & FAQ

Q1: What is the correct installation torque for the terminal connections on the 1SDA068165R1?
A: Per ABB’s installation manual for the TMax XT2 frame, terminal tightening torque is 13.5 N·m for the main power terminals. Always use a calibrated torque wrench and verify conductor insulation stripping length (22mm recommended) to ensure full contact surface engagement and prevent thermal hotspots.

Q2: Which firmware versions are compatible with the Ekip trip unit on this breaking part?
A: The 1SDA068165R1 breaking part is compatible with all Ekip trip unit generations (Ekip Touch, Ekip G Touch, Ekip Hi-Touch). Firmware compatibility is managed at the trip unit level, not the breaking part. Consult ABB’s Ekip Connect software (v3.x and above) for firmware update procedures and compatibility matrices.

Q3: How does the XT2H differ from the XT2S and XT2N variants in terms of breaking performance?
A: The XT2H (High Performance) achieves up to 50 kA breaking capacity at 400V AC, versus XT2S (Standard) at 36 kA and XT2N (Normal) at 25 kA. The H-class arc chute uses enhanced contact geometry and arc runner materials to achieve superior fault energy absorption — essential for bus-tie and incomer positions in high fault-level networks.

Q4: What is the warranty claim process for the 1SDA068165R1?
A: Units covered under our 1-year warranty are eligible for replacement or repair upon submission of a fault report, photographic evidence of the defect, and the original purchase invoice. Claims are processed within 5 business days. Warranty does not cover damage resulting from installation errors, overcurrent events exceeding rated breaking capacity, or unauthorized modifications.

Q5: Can the 1SDA068165R1 be used in a draw-out configuration?
A: No. The 1SDA068165R1 is the fixed (F) breaking part variant, designed for front-mounted panel installation. For draw-out (W) configurations, the corresponding withdrawable version with different accessory mounting provisions must be specified. Confirm your switchgear cubicle design before ordering.

Q6: Is zone-selective interlocking (ZSI) supported with this breaking part?
A: ZSI functionality is available when the 1SDA068165R1 is paired with an Ekip-series electronic trip unit. ZSI reduces arc flash energy by accelerating trip time at the fault location while restraining upstream breakers — a key feature for arc flash mitigation programs in compliance with NFPA 70E and IEC 62271.
