Why Choose the ABB E6H-A 5000 PR121/P-LSI Air Circuit Breaker?

The ABB E6H-A 5000 PR121/P-LSI, order code 1SDA058043R1, is a high-current SACE Emax air circuit breaker engineered for protection and switching in demanding low-voltage power distribution systems. Part of the ABB SACE Emax E6H series, this three-pole fixed circuit breaker combines a 5000 A rated current with the PR121/P electronic overcurrent release.

The breaker is equipped with LSI protection, providing long-time overload, short-time short-circuit and instantaneous short-circuit protection. Its PR121/P-LSI R5000 electronic release supports coordinated protection of high-current distribution circuits, helping safeguard busbars, transformers, generators, cables and connected electrical equipment against damaging overcurrent conditions.

This version features a three-pole fixed configuration with horizontal rear terminals and is designed to UL 1066. It provides rated service short-circuit breaking capacities of 125 kA at 240 V AC and 85 kA at 480–600 V AC, while the 75,000 A instantaneous protection reference supports rapid response to severe fault conditions.

Key Advantages

  • High-current ABB SACE Emax E6H air circuit breaker for demanding power distribution.
  • 5000 A rated current for large industrial and infrastructure electrical systems.
  • Three-pole fixed configuration for three-phase power distribution.
  • PR121/P electronic trip unit for dependable overcurrent protection.
  • LSI protection functions provide long-time, short-time and instantaneous protection.
  • 85 kA rated service short-circuit breaking capacity at 480 V AC for high-fault-level applications.

Key Features

  • ABB SACE Emax E6H-A 5000 series.
  • 5000 A rated current and rated uninterrupted current.
  • Three-pole breaker configuration.
  • PR121/P-LSI R5000 electronic overcurrent release.
  • 75,000 A instantaneous protection reference.
  • Fixed execution with horizontal rear terminals.
  • Fitted with four auxiliary contacts.
  • Integrated circuit-breaker open/closed position indication.

Reliable Protection for High-Current Power Distribution

The ABB SACE Emax E6H platform is designed for high-current electrical distribution where substantial load currents and prospective fault levels require robust switching and protection. With a 5000 A current rating and H-level short-circuit performance, the E6H-A is particularly suited to large main distribution boards, industrial switchgear, transformer and generator systems and critical power infrastructure.

The PR121/P electronic release provides configurable electronic overcurrent protection within the Emax platform. In this LSI configuration, it combines long-time overload protection, short-time protection for selective system coordination and instantaneous protection for rapid interruption of severe short-circuit faults.

Typical Applications

  • Main low-voltage distribution switchboards.
  • Large industrial power distribution systems.
  • Manufacturing and process plants.
  • Commercial and infrastructure electrical installations.
  • Transformer secondary protection and distribution.
  • Generator and standby power distribution systems.
  • High-fault-level switchgear and power control assemblies.
