1° The Air breaker SACE ABB is a brand new item , Full set with its own box and accessories.
2° An ABB 1600A circuit breaker (such as an ABB SACE Tmax MCCB or Air Circuit Breaker) is used to protect high-current, low-voltage electrical distribution systems (typically 400V to 690V AC) against overloads, short-circuits, and ground-faults.
3° Main Incoming Protection: Serves as the primary main breaker for commercial buildings, factories, or large facilities, receiving power directly from utility transformers.
4° Industrial Installations: Safeguards heavy machinery, motor control centers, and main switchboards from catastrophic fault currents (often rated for high breaking capacities like 50kA to 85kA).
5° Generator and Transformer Protection: Acts as an isolation and protection switch for backup generator sets and distribution transformers
