Three‑pole TMF release with front terminals enables fast, safe fault isolation and straightforward panel mounting, reducing arc flash exposure and service time for maintenance personnel. This directly translates to improved uptime and lower labor costs in critical production environments. The device supports a 35 A rated current with a 600 V operating voltage, delivering reliable protection for distribution boards and transformer feed lines while maintaining compact, manufacturer‑recommended wiring practices for busbar connections (32.5–100 mm²). The fixed XT2 design, M6 main circuit screws, and a 6 N·m tightening torque ensure dependable, vibration‑resistant connections in harsh industrial settings, minimizing retightening cycles and contact resistance over time. Compliance with UL489, CSA CS22.2, and CE standards reduces regulatory risk and simplifies audits, while RoHS/REACH declarations support sustainability goals and waste management targets. Installation compatibility with SACE Tmax XT family enhances spare‑parts compatibility across sites, reducing inventory complexity and downtime during replacements. In practice, engineers gain faster commissioning, safer maintenance windows, and a clear path to lifecycle cost reduction without compromising protection performance.

FAQs
The 1SDA074793R1 is designed for fixed front terminal mounting with 3P XT configurations. It accepts busbar sizes from 32.5 to 100 mm² and uses standard M6 main circuit screws, simplifying panel integration and reducing rework during retrofit projects. Ensure correct tightening to 6 N·m and verify alignment with existing Tmax XT family components for seamless compatibility.
Key specs include rated current In of 35 A, rated voltage Ur of 600 V, rated uninterrupted current Iu of 125 A, rated instantaneous short‑circuit current setting Ii of 400 A, and a 3P configuration with TMF release. The device complies with UL489 and CSA CS22.2, enabling compliant protection in both North American and European installations when used within its operating range.
Yes, the XT2 family is designed for transformer and distribution protection in low‑voltage networks. The 3P arrangement with TMF release supports reliable short‑circuit interruption, while the front-terminal design simplifies wiring to transformer feeders. For legacy transformer protection schemes, confirm busbar sizing, voltage rating, and coordination with upstream protective devices to ensure selective tripping.
The product carries UL489/CSA CS22.2 certifications, CE conformity, and a DoC, plus a UL certificate (1SDL000163R0112) and a CSA intrinsic safety certificate (9AKK10103A3906). These attest to electrical safety, cross‑border compliance, and environmental/regulatory standards, reducing procurement risk and simplifying audits for multinational facilities.
The MCCB’s durable front‑terminal design and TMF release reduce service time and maintenance costs by enabling quicker fault isolation. Its compatibility with the Tmax XT ecosystem lowers spare‑part inventory and improves lifecycle planning. Expect lower downtime, faster commissioning, and predictable protection performance, contributing to a favorable total cost of ownership over the equipment’s lifespan.
