1SDA056068R1 ABB E2L1250 1250 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E2L1250 1SDA056068R1 Air Circuit Breaker?

The ABB E2L1250 1SDA056068R1 is a high-performance SACE Emax air circuit breaker (ACB) moving part designed for protection and switching in demanding high-current low-voltage electrical distribution systems. Part of the proven ABB SACE Emax E2 series, this three-pole withdrawable breaker combines a 1250 A rated current with the advanced PR122/P-LSI electronic trip unit for dependable overload, short-time and instantaneous short-circuit protection.

Designed for industrial, infrastructure and commercial power distribution applications, the E2L1250 provides exceptionally high short-circuit interruption performance. The PR122/P-LSI electronic overcurrent release provides L, S and I protection functions, supporting selective coordination while helping protect conductors, busbars and connected equipment against sustained overloads and short-circuit currents.

This model is a three-pole withdrawable moving part rated for operation up to 690 V AC. The E2L performance level provides a rated ultimate short-circuit breaking capacity of 130 kA at 415 V AC, while its withdrawable construction supports convenient inspection, servicing and replacement when used with the corresponding SACE Emax E2 fixed part.

High-Performance Protection for Demanding Distribution Systems

The ABB E2L1250 is engineered for low-voltage installations where exceptionally high prospective short-circuit currents require substantial interruption capability. With an ultimate breaking capacity of 130 kA at 415 V AC, this E2L configuration is well suited to main switchboards, transformer-fed distribution systems and industrial networks located close to high-capacity power sources.

The PR122/P-LSI electronic trip unit provides long-time protection against sustained overloads, short-time delayed protection for selective short-circuit coordination and instantaneous protection against severe fault currents. Combined with the withdrawable SACE Emax platform, this configuration provides dependable high-current protection while allowing the breaker moving part to be withdrawn from its compatible fixed part for servicing or replacement.

Typical Applications

• Main low-voltage switchboards and distribution boards.
• Industrial power distribution systems.
• Transformer secondary and feeder protection.
• Manufacturing and process plants.
• Commercial and infrastructure electrical installations.
• High fault-level distribution networks.
