1SDA056028R1 ABB E2S2000 2000 A 4-Pole Fixed Air Circuit Breaker

Why Choose the ABB E2S2000 1SDA056028R1 Air Circuit Breaker?

The ABB E2S2000 1SDA056028R1 is a high-performance SACE Emax air circuit breaker (ACB) designed for protection and switching in high-current low-voltage electrical distribution systems. Part of the proven ABB SACE Emax E2 series, this four-pole fixed circuit breaker combines a 2000 A rated current with the advanced PR122/P-LSI electronic trip unit for dependable overload, short-time and instantaneous short-circuit protection.

Designed for demanding industrial and commercial power distribution applications, the E2S2000 provides reliable circuit protection while supporting selective coordination within low-voltage switchboards. The PR122/P-LSI electronic overcurrent release provides L, S and I protection functions, helping protect conductors and connected equipment against sustained overloads and short-circuit conditions.

This model is a four-pole fixed circuit breaker equipped with rear flat horizontal terminals for practical switchboard and busbar integration. Rated for operation up to 690 V AC, the E2S performance level provides a rated ultimate short-circuit breaking capacity of 85 kA at 415 V AC and 65 kA at 690 V AC.
