SIEMENS 3WA Air Circuit Breakers
SIEMENS 3WA Air Circuit Breakers
Ever stricter standards and increasingly automated infrastructure and systems require fail-safe power distribution. Discover the new SENTRON 3WA air circuit breakers – they let makers simply achieve what they want to achieve.
- 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 of 55 kA to 150 kA at 500 V AC
- Simple extension of functions, thanks to uniform accessories for all frame sizes
- A single electronic trip unit that meets all requirements
The advantages: How global makers benefit
- Transparent power data can improve energy efficiency by up to 30%.
- Lower penalty payments for grid operators in the event of electricity outages
- Robust air circuit breakers can withstand voltage fluctuations, minimizing the risk of system faults.
- Whereas wiring design used to take up to seven hours, it can now be done at the push of a button, resulting in huge time savings.
- System tests confirm a combination of robust mechanics, automated diagnostics, and webbased upgrades increase the real service life of the circuit breaker, if properly maintained, to potentially as long as 30 years – which represents 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.
