1SDA057112R1 ABB E6V5000 PR121/P-LI 5000A 4-Pole Fixed Air Circuit Breaker

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

The ABB 1SDA057112R1, product designation E6V5000PR121/P-LIIn=5000A4pFH, is a high-performance SACE Emax air circuit breaker (ACB) designed for switching and protection in demanding low-voltage electrical distribution systems. Part of the ABB SACE Emax E6V series, this four-pole fixed circuit breaker combines a 5000 A rated current with the PR121/P-LI electronic overcurrent release.

The E6V5000 is engineered for high-current industrial, commercial and infrastructure distribution applications where dependable protection against overloads and severe short circuits is essential. Its PR121/P-LI electronic trip unit provides long-time and instantaneous protection functions, helping safeguard busbars, cables, switchgear and connected electrical equipment against damaging overcurrent conditions.

The V-performance Emax platform is intended for installations requiring particularly high short-circuit performance. This version features a four-pole fixed configuration, making it suitable for permanent installation within high-capacity switchboards where four-pole switching and electronic overcurrent protection are required.

Advanced 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 the high-performance V breaking-capacity level, 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 controlled.

The PR121/P-LI electronic release provides complementary long-time and instantaneous protection functions. Long-time protection responds to sustained overload conditions that could otherwise damage conductors and electrical equipment, while instantaneous protection provides rapid interruption during severe short-circuit faults. Combined with its four-pole fixed construction, the E6V5000 provides robust protection for high-current power distribution installations.

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 distribution systems requiring electronic LI protection.
