Four-pole fixed front-terminal design streamlines mounting and reduces wiring errors in control panels, enabling faster commissioning and safer maintenance. This configuration supports clean terminations for busbar ranges of 32.5 to 100 mm², translating to flexible installation across common industrial feeders. The business impact is clear: lower wiring labor costs, fewer field faults, and improved panel reliability in high-demand environments. The Ekip Dip LS/I solid-state release provides precise, repeatable tripping actions, improving protection accuracy for motors and transformers and reducing the risk of unnecessary outages. In practice, technicians achieve consistent performance with minimal adjustment, boosting uptime in automation lines and process sectors. Compatibility with the Tmax XT family ensures straightforward retrofits and standardized spare parts across sites. This aligns with installation best practices and supports lean maintenance programs.

FAQs
This unit uses a four-pole, fixed front-terminal design for straightforward mounting in standard industrial panels. It supports busbar connections from 32.5 to 100 mm² and requires a tightening torque of 6 N·m. The product footprint and terminal layout are suited for front-entry wiring, with a recommended Main Circuit screwdriver size of M6. Typical installation time is reduced due to the compact XT2L format and standardized dimensions (120 mm width, 130 mm height, 82.5 mm depth).
Rated current is 100 A with a rated operating voltage of 600 V AC and a rated uninterrupted current of 125 A. Short-circuit performance per UL489/CSA is up to 200 kA at 240 V, 100 kA at 480 V, and 35 kA at 600 V. The device uses a 4P configuration with front terminal connections and a bolt-type terminal. This makes it suitable for large-control panels and feeder protection.
Yes. The 4P XT2L model includes an Ekip Dip LS/I release for reliable AC protection with fast opening (approximately 30 ms) and robust mechanical durability. Its 32.5–100 mm² busbar connection supports motor feeders, and the front-terminal design simplifies replacement or upgrades in existing motor control centers, minimizing downtime during maintenance windows.
The product carries UL489 and CSA certifications, along with a CE Declaration of Conformity for Tmax XT2. ABB provides end-of-life documentation, including disassembly instructions and an Environmental Product Declaration (EPD). It also aligns with RoHS and REACH requirements, and CMRT reporting supports sustainable sourcing. This combination helps with regulatory compliance and green procurement programs.
Durability is anchored by 25,000 mechanical cycles and 8,000 electrical cycles per hour, reducing replacement frequency in high-switching applications. The front-terminal, bolt-type connections facilitate fast, secure maintenance checks. Combined with rapid replacement, low downtime, and standardization within the SACE Tmax XT family, you can expect lower total cost of ownership through fewer field faults and streamlined spare parts management.
