Why Choose the ABB E2N 1000 PR122/P-LSIG 1000A 3P Withdrawable Air Circuit Breaker?
The ABB 1SDA059278R1 is a high-performance SACE Emax E2N air circuit breaker moving part designed for protection and switching in demanding low-voltage power distribution systems. This configuration combines a 1000 A rated current, three-pole construction and withdrawable design with the advanced PR122/P-LSIG electronic overcurrent release.
Part of the ABB SACE Emax family, the E2N 1000 provides dependable protection for industrial, commercial and infrastructure distribution systems. The PR122/P-LSIG release provides long-time, short-time, instantaneous and earth-fault protection functions, allowing the circuit breaker to respond effectively to overloads, short circuits and ground-fault conditions.
This model is the three-pole withdrawable moving part (W MP) version of the E2N 1000, enabling the breaker to be disconnected and removed from its compatible fixed part for inspection or maintenance. With a rated uninterrupted current of 1000 A and an E2N breaking capacity of 65 kA at 400/415 V AC, it is engineered for robust low-voltage switchboards and high-current distribution applications.
