Why Choose the ABB E4V4000 PR123/P-LSIG 4000A Air Circuit Breaker?

The ABB 1SDA056919R1, product type E4V4000PR123/P-LSIGIn=4000A3pF, is a high-performance SACE Emax air circuit breaker (ACB) designed for protection and switching in demanding low-voltage electrical distribution systems. Part of the advanced ABB SACE Emax E4V series, this three-pole fixed circuit breaker combines a 4000 A current rating with the advanced PR123/P-LSIG electronic overcurrent release.

The E4V4000 is engineered for high-current industrial, commercial and infrastructure power distribution applications where comprehensive protection against overloads, short circuits and earth faults is required. Its PR123/P-LSIG electronic trip unit provides long-time, short-time, instantaneous and ground-fault protection functions, supporting accurate protection and selective coordination within complex electrical distribution networks.

With a rated current of 4000 A and the high short-circuit performance of the E4V platform, this SACE Emax breaker is suitable for substantial power distribution installations with high prospective fault currents. The three-pole fixed configuration provides a robust solution for integration into high-capacity switchboards, while the PR123/P platform adds advanced protection and measurement capabilities for demanding electrical installations.

Advanced Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E4V4000 protect low-voltage distribution networks by interrupting potentially damaging currents when abnormal operating conditions occur. The E4V platform combines a high continuous current capability with substantial short-circuit performance, making it suitable for main switchboards, industrial distribution systems and critical installations where high prospective fault currents must be safely controlled.

The PR123/P-LSIG electronic release provides four complementary protection functions. Long-time protection responds to sustained overloads, short-time protection supports selective coordination during fault conditions, instantaneous protection provides rapid interruption of severe short circuits, and ground-fault protection helps protect the installation against earth-fault currents. Its advanced electronic functionality makes the PR123/P particularly suitable for sophisticated power distribution networks requiring comprehensive protection and system monitoring.

Typical Applications

  • Main low-voltage electrical distribution switchboards.
  • Industrial power distribution systems.
  • High-current switchgear assemblies.
  • Transformer secondary protection and distribution.
  • Generator and critical power distribution systems.
  • Manufacturing and process plants.
  • Commercial and infrastructure electrical distribution.
  • High-fault-level installations requiring advanced LSIG protection.
