When it comes to ensuring the reliability and safety of electrical systems in industrial and commercial settings, selecting the right circuit breaker is crucial. The Motor Operated ACB (Air Circuit Breaker) detailed here stands out as a robust choice for professionals seeking dependable performance under demanding conditions.
This ACB boasts a rated current range from 500 to 1250 A, making it versatile enough to handle various applications while maintaining optimal operational efficiency. Its rated impulse withstand voltage of 12 kV provides an added layer of protection against transient overvoltages, which is essential for safeguarding sensitive equipment.
Designed with a rated insulation voltage of 1000 VAC and a rated voltage of 690 VAC, this breaker ensures compatibility with numerous electrical systems. It features a breaking capacity of 66 kA, offering substantial fault-clearing capabilities that help maintain system integrity during unexpected overloads or short circuits.
The trip unit integrated into this model is the Ekip Touch LSIG, known for its advanced protection functions including long-time (L), short-time (S), instantaneous (I), and ground fault (G) protections. This sophisticated trip unit enables precise monitoring and control, enhancing both safety and efficiency.
Power loss is another critical factor in any electrical component; this model exhibits power loss at just 244 W. This efficiency can contribute significantly to energy savings over time, particularly in large-scale operations where multiple units are deployed.
With three poles, the breaker supports balanced load distribution across phases—a vital feature for maintaining stability in polyphase systems. The frame size E1.2 indicates its compact yet sturdy construction, suitable for installations where space might be limited but performance cannot be compromised.
The terminal type specified as horizontal rear spread allows for straightforward installation and connection within switchgear assemblies or other setups requiring rear access terminals. This design consideration simplifies maintenance procedures by providing easy access points without disrupting overall system architecture.
Compliance with IEC 309 standards underscores the product's adherence to international quality benchmarks, ensuring that users can trust its performance across diverse environments globally. Whether you're upgrading existing infrastructure or planning new installations, this motor-operated ACB meets rigorous demands with reliability you can count on every day.
