Feature → Business Impact → Application: Fixed front-terminal four-pole design simplifies wiring and reduces panel depth, enabling faster assembly and easier maintenance in switchgear upgrades and new panel builds, especially in 600Y/347 V AC environments. This aligns with 20 A nominal current and 125 A rated uninterrupted current, delivering predictable protection for feeders and transformers in commercial and industrial installations. Feature → Business Impact → Application: TMF release with a 30 ms SOR/UVR opening profile supports fast clearing of faults, minimizing arc exposure and downtime in critical processes such as HVAC, water treatment, and manufacturing lines. Feature → Business Impact → Application: UL489/CSA certification and IEC/UL compliance reduce regulatory risk for assemblies, enabling easier customer approval and market access in North America and international projects. Feature → Business Impact → Application: Front-terminal bolt connections with 6 N·m tightening torque provide secure terminations even in crowded enclosures, improving reliability and reducing rework on site for panel manufacturers and retrofit projects. Feature → Business Impact → Application: Rated voltage of 600Y/347 V AC and 500 V DC supports mixed AC/DC distribution schemes, offering flexibility for feeder protection in mixed-power facilities and automation panels. Feature → Business Impact → Application: Energy-conscious design with 1.8 W per pole power loss at rated conditions supports cooler enclosures and lower total cost of ownership in high-density control rooms. Feature → Business Impact → Application: Disassembly instructions and End Of Life guidance (Tmax XT XT1) assist with efficient recycling and responsible waste management, aligning with sustainability targets across automotive, process, and industrial settings. Feature → Business Impact → Application: EPD and recyclability data (55.9% design for resource loops) provide quantifiable environmental performance for ESG reporting and supplier assessments in capital projects and fleet upgrades.

FAQs
The device uses front terminals with bolt connections and a tightening torque of 6 N·m, designed for secure front-entry wiring. It supports busbar connections from 45.5 to 80 mm² and is compatible with 4P configurations in fixed front-terminal layouts, making it suitable for compact panels and retrofit projects.
Rated current is 20 A with a rated operational voltage of 600Y/347 V AC and 500 V DC. It provides an uninterrupted current rating of 125 A, a rated instantaneous setting of 500 A, and an interrupting rating per UL489 up to 65 kA at 240 V, 35 kA at 480 V, and 22 kA at 600Y/347 V AC. It also supports 4P configurations and TMF release.
Yes. With 4P fixed front terminals and TMF release, the XT1S is designed for transformer protection in industrial power distribution. Its TM release and front-access design streamline installation and coordination in transformer feed panels, while UL489/CSA compliance ensures reliable protection in critical power systems.
This MCCB carries UL489 and CSA certifications, a CE Declaration of Conformity, RoHS and REACH declarations, and CMRT. It also aligns with ABB EcoSolutions and provides environmental data such as EPD for Tmax XT XT1 and a recyclability rate of 55.9% per EN45555, supporting sustainability reporting.
Expect reduced downtime from fast fault clearing (30 ms TMF/UVR opening), secure front-terminals for reliable terminations, and lower maintenance due to standardized SACE Tmax XT components. Energy losses are minimized (1.8 W per pole under load), contributing to lower operating costs over the panel’s life and improved overall uptime.
