The chute housing encloses and protects the arc chute assembly, providing mechanical support and containing arc energy during circuit interruption to facilitate safe arc quenching.
Common materials include thermoset plastics (e.g., DMC, SMC), high-strength ceramics, and fiber-reinforced polymers, chosen for their thermal and mechanical properties.
Typical rated voltages are 12–40.5 kV and rated currents 630–3150 A, per IEC 62271-100 and IEC 62271-1. These are reference ranges; confirm for your application.
Check the manufacturer's datasheet for model-specific parameters such as rated voltage, current, breaking capacity, operating temperature, and protection degree. Ensure compliance with relevant standards like IEC 62271.
