1SDA057129R1 ABB E6V5000 PR121/P-LSI 5000A 4-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E6V5000 PR121/P-LSI 5000A 4-Pole Withdrawable Air Circuit Breaker?

The ABB 1SDA057129R1, product designation E6V5000PR121/P-LSIIn=5000A4pW, is a high-performance SACE Emax air circuit breaker moving part designed for switching and protection in demanding low-voltage electrical distribution systems. Part of the ABB SACE Emax E6V series, this four-pole withdrawable unit combines a 5000 A rated current with the PR121/P-LSI electronic overcurrent release.

The E6V5000 is engineered for high-current industrial, commercial and infrastructure distribution applications where dependable overload and short-circuit protection is essential. Its PR121/P-LSI electronic trip unit provides long-time, short-time and instantaneous protection functions, helping protect busbars, cables, switchgear and connected equipment while supporting selective coordination within complex electrical distribution networks.

This version uses a four-pole withdrawable configuration for integration with compatible ABB SACE Emax switchgear. The E6V performance class provides substantial fault-clearing capability, including an ultimate short-circuit breaking capacity of 150 kA at 415 V AC, making it suitable for installations with high prospective fault currents.

Reliable Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E6V5000 provide switching and protection for high-capacity low-voltage distribution networks. With a rated current of 5000 A and V-level short-circuit performance, the E6V platform is particularly suited to main incoming supplies, large switchboards, transformer secondary systems and industrial distribution networks where substantial electrical loads and high prospective fault currents must be safely managed.

The PR121/P-LSI electronic release provides three complementary protection functions. Long-time protection responds to sustained overload conditions, short-time protection enables controlled fault clearing and supports selective coordination, and instantaneous protection provides rapid interruption during severe short-circuit faults. The withdrawable construction further supports maintainability by allowing the breaker moving part to be removed from its compatible fixed section when inspection, servicing or replacement is required.

Typical Applications

• Main low-voltage electrical distribution switchboards.
• High-current industrial power distribution systems.
• Large switchgear and busbar assemblies.
• Transformer secondary protection and distribution.
• Manufacturing and heavy process plants.
• Data centre and critical infrastructure power distribution.
• Commercial and infrastructure electrical installations.
• High-capacity four-pole systems requiring withdrawable selective LSI protection.
