Why Choose the ABB E3V1600 PR121/P-LI 1SDA056592R1 Air Circuit Breaker?
The ABB 1SDA056592R1 is a high-performance SACE Emax E3 V air circuit breaker (ACB) designed for protection and switching in demanding low-voltage electrical distribution systems. As part of the ABB SACE Emax series, this three-pole fixed circuit breaker combines a 1600 A rated current with high short-circuit breaking performance for industrial, commercial and infrastructure power distribution applications.
The E3V1600 is equipped with an ABB PR121/P-LI electronic overcurrent release, providing long-time overload and instantaneous short-circuit protection. The LI protection functions provide dependable protection against sustained overcurrents and severe short-circuit faults, while the E3 V performance level is engineered for electrical systems with high prospective fault currents.
With a rated uninterrupted current of 1600 A, a rated operational voltage of up to 690 V AC and a three-pole fixed configuration, the 1SDA056592R1 is well suited to main distribution boards, industrial switchboards and high-current feeder applications. Its rear horizontal flat terminals support fixed switchboard installation, while a rated ultimate short-circuit breaking capacity of 130 kA at 400 V AC provides robust fault protection.
