Four-pole XT1 design with TMF release and front terminals delivers robust phase protection while simplifying wiring and service access. The four-pole configuration ensures coordinated protection across all three phases and neutral where applicable, reducing false trips and improving selectivity in motor and distribution panels. This makes it ideal for machine control cabinets and industrial switchgear where space is at a premium. Front-terminal bolt connections and a defined tightening torque of 6 N·m provide secure, vibration-tolerant terminations during commissioning and maintenance. Quick and reliable connections support faster assembly, lower error rates during wiring, and easier retrofits in existing panels using the XT1 family. This translates to lower commissioning time and improved field reliability. Rated current is 25 A with a rated operational voltage of 600Y/347 V and 500 V DC, ensuring safe operation across AC and DC bus configurations. This compatibility enables use in mixed-power environments common in industrial facilities and automation lines, reducing the number of SKUs required for different installations. High short-circuit interrupting ratings per UL489—65 kA at 240 V, 35 kA at 480 V, and 22 kA at 600Y/347 V—plus DC ratings (2P in series 42 kA, 4P in series 50 kA) provide strong protection against faults. This improves system uptime, minimizes damage during faults, and supports compliance with demanding electrical standards. EcoSolutions and environmental data—EPD, recyclability 55.9% per EN45555, disassembly instructions for Tmax XT XT1—back up sustainability goals. The device also uses RoHS/REACH-compliant materials and packaging disposal guidance, helping you meet corporate responsibility targets while maintaining performance. Ultra-compact dimensions and a front-terminal, bolt-based design support easy installation in crowded panels, with suitable busbar connection (45.5 to 80 mm²) and recommended screwdriver (Main Circuit M6) ensuring correct assembly. In addition, standard data sheets, WIRING diagrams, and installation instructions are readily available to reduce risk during upgrade projects.

FAQs
Use the front-terminal bolt connections and tighten to 6 N·m per pole. Connect to busbars within 45.5 to 80 mm², using the Main Circuit M6 screwdriver for proper engagement. Verify polarity and torque at each connection, then perform a functional check to confirm correct operation and trip settings before commissioning.
Rated current is 25 A, rated operational voltage is 600Y/347 V, with 500 V DC capability. It supports four poles (4P), has front-terminal connections, and offers a TMF release. Short-circuit ratings per UL489 are up to 65 kA at 240 V and 22 kA at 600Y/347 V AC, with DC ratings in series up to 50 kA for 4P configurations.
Yes. The product carries UL489 protection and CSA certification (UL certificate 1SDL000163R0111; CSA 9AKK10103A3905) and is accompanied by a CE Declaration of Conformity. REACH and RoHS declarations are provided, aligning with modern regulatory requirements for safe, compliant electrical protection.
Suitable for industrial power distribution panels, machine control cabinets, and mixed AC/DC bus environments (600Y/347 V AC, 500 V DC). Front-terminals simplify retrofits and maintenance in crowded panels, while the 4P XT1 configuration supports reliable protection in multi-phase systems common in manufacturing plants and data centers.
ABB EcoSolutions framework applies, with an EPD for Tmax XT XT1, a recyclability rate of 55.9% per EN45555, and disassembly instructions for Tmax XT XT1. RoHS/REACH compliance and packaging disposal guidance support corporate ESG targets while maintaining electrical performance and safety.
