The AT12 Tempower Air Circuit Breaker stands as a basis of electrical protection and reliability, designed by Terasaki Electric Co., Ltd. This air circuit breaker, with its impressive 3-pole, 1250A rating, is manufactured to meet the demanding needs of modern industrial and commercial power systems. Operating at a voltage of 660Vac and supporting frequencies of 50/60Hz, the AT12 is versatile enough to be used in a variety of settings, ensuring stable and safe power distribution. Its breaking capacities are significant: 35kA at 660V, 50kA at 550-600V, and 65kA at 220-500V. This wide range of interrupting capabilities ensures that the breaker can handle different fault conditions effectively, providing robust protection across various applications. The short time current ratings further underscore its reliability, with the AT12 capable of managing 50kA for 1 second and 45kA for 3 seconds, ensuring it can withstand and mitigate short-circuit conditions without compromise.
One of the standout features of the AT12 is its advanced over-current trip system, the AOP-1SA-A, which is finely tuned to offer precise and responsive protection. The long-time delay setting (I1) is rated at 1190A with a delay (T1) of 20 seconds at 1.2 times I1, allowing for controlled response to sustained overloads. The short time delay (I2) is set at 8330A with a delay (T2) of 220 milliseconds, providing rapid intervention during high current spikes. Additionally, the instantaneous trip setting (I3) at 11900A ensures immediate response to severe fault conditions, protecting equipment and ensuring system integrity. The AT12 also incorporates a variety of auxiliary and accessory features designed to enhance its functionality and ease of use. The magnet holds trigger (ATT-1) and the auxiliary switch (AXT-1C), rated at 3A3B, provide additional layers of control and monitoring. The under-voltage trip device (AUT-1B0) supports voltages from AC200-240, adding another dimension of protection against under-voltage conditions which can be crucial for maintaining system stability.
Designed with a motor charging system rated at AC220V (AOR-4L), the AT12 ensures reliable recharging and readiness for operation. The auxiliary switch is rated at 5A 5B, offering flexible integration options for various control and monitoring systems. These features collectively enhance the breakers operational readiness and reliability, ensuring that it performs consistently in demanding conditions. Manufactured in Japan, the Terasaki AT12 Tempower Air Circuit Breaker reflects the high standards of Japanese engineering and manufacturing. Every unit undergoes rigorous testing and quality assurance processes to ensure that it meets the exacting standards expected by professionals worldwide. Weighing 80 kg, the AT12 combines robustness with manageability, making it suitable for a range of installation scenarios from industrial plants to commercial buildings.
The Terasaki AT12 Tempower Air Circuit Breaker 3 Pole 1250A 50/60Hz is a good choice for those seeking reliable, high-performance circuit protection. Its comprehensive range of features, including advanced trip settings, robust breaking capacities, and auxiliary options, make it a versatile and dependable component in any electrical system. Whether used in heavy industrial applications or commercial power distribution networks, the AT12 delivers exceptional performance and composure, ensuring your electrical infrastructure is protected and operating efficiently.
