Yes, the portfolio for the UL market is designed to support international use in the following ways:

• The entire SENTRON 3WA air circuit breaker portfolio (3WA1, 3WA2, 3WA3) is based on a consistent system.
• The SENTRON 3WA air circuit breaker meets the requirements of UL1066 and IEC60947-2 and can be used worldwide. This is especially useful for switchgear manufacturers or OEMs who create systems for both standard areas.
• The SENTRON 3WA2 series is designed exclusively for the UL 489 market. 
  

• Transparent power data can drastically improve energy efficiency.
• Lower penalty payments for grid operators in the event of electricity outages
• Robust air circuit breakers (ACBs) can withstand voltage fluctuations, minimizing the risk of system faults.
• Greatly reduced wiring design time with the graphical SENTRON 3WA configurator.
• A combination of robust mechanics, automated diagnostics and web-based upgrades increase the real service life of the circuit breaker, if properly maintained, to potentially as long as 30 years — a huge reduction in system life-cycle costs.
• SENTRON 3WA air circuit breaker can be easily and inexpensively integrated into switchgear if the SENTRON 3WL air circuit breaker is already integrated.

• The SENTRON 3WL air circuit breaker further develops the proven, extremely robust design of its predecessor.
• Special versions (high short-circuit breaking capacity at high voltages): up to 125 kA at 1,000 V
• Accessories designed for the maximum service life of the air circuit breaker (ACB)
• The SENTRON 3WA is developed and manufactured in accordance with a certified quality management system complying with DIN EN ISO 9001:2008
• A user-friendly operation of electronic trip unit ETU600 via rotary switch, display or remote parameterization
• Consistent, end-to-end portfolio since 2001 thanks to the SENTRON 3WL and SENTRON 3WA air circuit breakers having the same dimensions and connection points
• Consistent, end-to-end circuit breaker portfolio up to 1,150 V AC
• Three sizes with rated currents of 630 A to 6,300 A for AC applications
• One frame size up to 4,000 A for DC applications
• High breaking capacity ICU from 55 kA to 150 kA at 500 V AC
• Simple extension of functions, thanks to uniform accessories for all frame sizes
• Two electronic trip units that cover all requirements

• Accessories can be retrofitted on site at any time
• ETU functions extendable by means of on-site upgrades (ETU600)
• COM190 PROFINET-IO/Modbus TCP module for connection to higher-level management systems; designed as a combination module to use multiple protocols simultaneously (Modbus TCP and PROFINET)
• Switched Ethernet functionality for optimized architecture, engineering, and redundancy while maintaining highest performance

• You can carry out a simple annual inspection by yourself
• You can replace parts as needed by yourself (no Siemens personnel required)
• Under some environmental conditions, inspections are required only once every four years
• Automatic self-monitoring of functioning of the SENTRON 3WA air circuit breaker
• Condition monitoring with ETU600
• Cybersecurity functions for secure communication

• Reduced resource use through digital documentation via ID Link, significantly lowering paper consumption compared to the predecessor 3WL.
• High durability with up to 30,000 operating cycles, supporting long-term use and reducing lifecycle material demand.
• Energy-efficient operation thanks to low temperature derating and integrated energy data acquisition, enabling optimization in line with ISO 50001.
• Modular, repairable design with easy maintenance and widely available spare parts to minimize waste and extend service life.
• Future‑proof upgradability, reducing the need for hardware replacement as requirements evolve.
• Availability of an EPD Type II with full life‑cycle impact assessment, offering transparency on environmental performance and product carbon footprint.

• Rated current (AC): 630–6300 A
• DC rating: up to 4000 A
• Breaking capacity Icu: up to 150 kA @ 500 V AC
• Frame sizes: 3
• Standards: IEC 60947‑2, UL 1066; UL 489 (3WA2)
• Protection: overload, short circuit, ground‑fault
• Advanced detection: reverse energy flow
