1SDA056899R1 ABB E4V3200PR122/P-LI 3200A 3-Pole Air Circuit Breaker Moving Part

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

The ABB E4V3200PR122/P-LI, order code 1SDA056899R1, 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 PR122/P electronic overcurrent protection release.

The breaker is equipped with an ABB PR122/P-LI R3200 electronic overcurrent release, providing long-time overload and instantaneous short-circuit protection. This LI protection arrangement is suited to main incomers, transformer secondary circuits and high-current feeders where accurate overload protection and rapid interruption of severe short-circuit faults are required.

With a rated uninterrupted current of 3200 A, a three-pole withdrawable moving-part configuration and an ultimate short-circuit breaking capacity of 150 kA at 400 V AC, the E4V3200PR122/P-LI is engineered for switchgear with exceptionally high prospective fault currents. Its withdrawable construction enables the breaker moving part to be isolated and withdrawn from the corresponding fixed part for inspection, servicing or replacement.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 delivers exceptionally high fault-interruption capability, making it particularly suitable for main incomers, transformer secondary circuits and major feeders where very high prospective short-circuit currents can occur.

The PR122/P electronic release continuously monitors circuit current and initiates breaker operation when configured protection thresholds are exceeded. In this LI configuration, long-time protection responds to sustained overload conditions while instantaneous protection provides rapid interruption of 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.
• Networks with exceptionally 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.
