1SDA056045R1 ABB E2S2000 2000 A 4-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E2S2000 1SDA056045R1 Air Circuit Breaker?

The ABB E2S2000 1SDA056045R1 is a high-performance SACE Emax air circuit breaker (ACB) moving part 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 withdrawable breaker combines a 2000 A rated current with the advanced PR122/P-LSIG electronic trip unit for comprehensive overload, short-time, instantaneous and earth-fault protection.

Designed for demanding industrial and commercial power distribution applications, the E2S2000 provides reliable circuit protection while its withdrawable construction supports convenient inspection, servicing and replacement when installed with the appropriate Emax fixed part. The PR122/P-LSIG electronic overcurrent release provides L, S, I and G protection functions, supporting selective coordination and protection against sustained overloads, short circuits and earth faults.

This model is a four-pole withdrawable moving part rated at 2000 A with an operational voltage up to 690 V AC. Its E2S performance class provides a rated ultimate short-circuit breaking capacity of 85 kA at 415 V AC and 65 kA at 690 V AC, making it suitable for substantial distribution systems requiring high fault-current interruption capability.

Comprehensive Protection for High-Current Distribution Systems

Air circuit breakers such as the ABB E2S2000 provide switching and protection at the main and distribution levels of low-voltage electrical installations. Their high current capability, substantial short-circuit interruption performance and electronic protection technology make them particularly suitable for switchboards supplying industrial machinery, infrastructure, commercial facilities and other substantial electrical loads.

The PR122/P-LSIG electronic trip unit provides long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection. Combined with the withdrawable SACE Emax platform, this configuration delivers comprehensive electrical protection while allowing the breaker moving part to be withdrawn from its compatible fixed part for servicing or replacement.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.
• Manufacturing and process plants.
• Commercial and infrastructure electrical installations.
• Transformer secondary and feeder protection.
• High-current machinery and production systems.
