Hitachi Industrial Equipment Systems Low Voltage Air Circuit Breaker AS Series
Hitachi Industrial Equipment Systems
Low-voltage air circuit breaker AS series that eliminates the intermediate conductor and achieves thin design and high-speed interruption.
Features The fixed contact hinge part and the main contactor are directly connected, eliminating the intermediate conductor and achieving miniaturization. Compared to conventional products, it has become significantly thinner, allowing for space-saving in distribution boards. - Equipped with a new type of OCR, enhancing reliability. - The general-purpose type comes in three sizes: 800-2,000A, 2,500-3,200A, and 4,000A, with the panel cut being the same across all models, making distribution board design easier. - Emphasizing front access, installation and maintenance inspections on the distribution board are made easier. - Zero arc space, capable of multi-layer stacking. - Achieves high-speed interruption with a two-point interruption structure.
