1SDA056884R1 ABB E4V3200PR122/P-LSI 3200A 3-Pole Air Circuit Breaker

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

The ABB E4V3200PR122/P-LSI, order code 1SDA056884R1, is a high-performance 3200 A three-pole air circuit breaker designed for demanding low-voltage power distribution systems. Part of the ABB SACE Emax E4 series, this fixed breaker 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. This LSI protection configuration supports selective coordination while safeguarding cables, busbars, transformers and downstream equipment against sustained overloads and short-circuit faults.

With a rated current of 3200 A, a three-pole fixed configuration and rear horizontal terminals, the E4V3200PR122/P-LSI is engineered for permanent integration into high-capacity low-voltage switchgear. The E4V performance class is intended for installations with exceptionally high prospective fault currents where robust interruption performance and dependable circuit protection are required.

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 engineered for demanding installations where very high prospective short-circuit currents require robust interruption capability.

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 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.
