Description

The 3P 320A 1500V Air Switch Thermal Conventional Molded Case Circuit Breaker is engineered for superior electric protection and reliability in high-voltage applications. This circuit breaker features an innovative busbar design that enhances safety against electric shocks, ensuring that personnel can operate live equipment without risk. The shell provides comprehensive protection, eliminating potential earth faults caused by external elements such as dampness, dust, and foreign objects. Its phase-closed structure mitigates the likelihood of alternate short circuits, enhancing overall system safety.

One of the standout features of this circuit breaker is its ability to significantly reduce internal temperature rise within the cabinet. By integrating the busbar connection row with the circuit breaker, it minimizes the number of connection points, leading to a 20% decrease in temperature and improved thermal management. Installation is both standardized and efficient, with a frame space of 45mm that conserves busbar connection materials by 30%, reduces installation volume by 20%, and boosts installation efficiency by 60%.

Furthermore, the circuit breaker utilizes a cutting-edge high-score breaking structure that enables zero arcing distance, enhancing safety during operation. This sophisticated design incorporates an arc-extinguishing structure, air flow channel system, and optimized arc isolation features. With a rated current of 320A and a maximum voltage of 1500V, this circuit breaker is a robust choice for demanding applications.
