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.
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.
