Feature → Business Impact → Application: 3P front-terminal design enables quick, secure busbar connections with a tightening torque of 6 N·m, reducing field installation time and improving reliability in dense switchgear assemblies. This supports faster commissioning in motor control centers and transformer protection schemes, delivering measurable reductions in install cost and risk. Feature → Application: TMF release provides reliable thermal-magnetic tripping for overload and short-circuit events, minimizing nuisance trips and downtime in high-demand environments such as CNC production lines and packaging facilities. Feature → Business Impact → Application: Rated current of 45 A and rated operational voltage up to 600Y/347 VAC (and 500 V DC) cover typical industrial feeders, enabling safe protection of distribution panels without over-specification. Feature → Application: Front-terminal connection and bolt-type terminals simplify maintenance and retrofits in existing XT frames, improving serviceability and reducing spare-part complexity. Feature → Business Impact → Application: High short-circuit interrupting ratings (UL489) across multiple voltages ensure reliable protection for transformers, generators, and busbar systems, supporting compliance with UL/CSA requirements and reducing downtime during fault conditions. Feature → Application: Mechanical durability of up to 25,000 cycles and electrical durability of up to 8,000 cycles deliver predictable life cycles in continuous production environments, lowering replacement costs and total cost of ownership. Feature → Business Impact → Application: 3P XT1 configuration with fixed front terminals, along with EN45555 and CMRT/REACH/ROHS compliance, supports sustainable end-of-life handling and regulatory reporting, simplifying procurement and environmental responsibilities.

FAQs
Install the 3P XT1 breaker with front terminals using the recommended Main Circuit Screwdriver (M6). Tighten to 6 N·m per terminal to ensure a secure, vibration-resistant connection. Follow the XT1 dimensional drawings for mounting clearance and avoid over-bending conductors to maximize reliability in switchgear assemblies.
Key specs include 45 A rated current, rated operational voltage of 600Y/347 VAC or 500 V DC, rated uninterrupted current of 125 A, and a short-circuit instantaneous setting of 500 A. The device is a 3-pole unit with TMF release, designed for front-terminal connections and a 50 A setting range.
Yes. It carries UL489/CSA CS22.2 applicability, with UL Certificate 1SDL000163R0111 and CSA certification 9AKK10103A3905, plus CE Declaration of Conformity. This ensures suitability for UL/CSA compliant electrical protection in industrial facilities.
Interrupting ratings vary by voltage: 240 V AC up to 50 kA, 480 V AC up to 25 kA, and 600Y/347 V AC up to 18 kA. For 250 V DC, 2 poles in series provide 35 kA, and 500 V DC with 4 poles in series also provides 35 kA, ensuring robust protection against high-energy faults.
Expect electrical durability of about 8,000 cycles and mechanical durability up to 25,000 cycles, reducing replacement frequency. The front-terminal design simplifies inspection and replacement, while compliance with RoHS/REACH and end-of-life disassembly instructions support easier maintenance planning and regulatory reporting.
