1SDA056900R1 ABB E4V3200PR122/P-LSI 3200A 3-Pole Air Circuit Breaker Moving Part

Why Choose the ABB E4V3200PR122/P-LSI 3200A Air Circuit Breaker?

The ABB E4V3200PR122/P-LSI, order code 1SDA056900R1, is a high-performance 3200 A three-pole withdrawable air circuit breaker moving part designed for demanding low-voltage power distribution systems. Part of the ABB SACE Emax E4 series, this configuration combines the E4V very-high short-circuit performance class with the advanced PR122/P electronic overcurrent protection release.

The breaker is equipped with an ABB PR122/P-LSI R3200 electronic overcurrent release, providing long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. The LSI protection configuration supports selective coordination while protecting cables, busbars, transformers and downstream equipment against sustained overloads and short-circuit faults.

With a rated current of 3200 A and a three-pole withdrawable moving-part configuration, the E4V3200PR122/P-LSI is engineered for high-capacity switchgear where protection performance, maintainability and continuity of service are important. The moving part is designed for use with the corresponding ABB SACE Emax E4V fixed part, allowing withdrawal for inspection, servicing or replacement.

Reliable Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E4 protect low-voltage electrical networks against damaging overcurrents while providing dependable switching and isolation of high-current circuits. The E4V performance class is designed for demanding installations where substantial prospective short-circuit currents require robust interruption capability and reliable protection.

The PR122/P electronic release continuously monitors circuit current and initiates breaker operation when configured protection thresholds are exceeded. In this LSI configuration, long-time protection responds to sustained overloads, short-time protection provides a controlled response that can support selective coordination, and instantaneous protection rapidly interrupts severe short-circuit faults.

Typical Applications

• Main low-voltage switchboards and power distribution assemblies.
• Industrial high-current power distribution systems.
• Transformer secondary and main incomer protection.
• Large feeder and busbar circuits requiring selective protection.
• Networks with high prospective short-circuit currents.
• Manufacturing and process plant electrical systems.
• Data centres and mission-critical electrical infrastructure.
• Commercial buildings, utilities and critical infrastructure installations.
