1SDA056996R1 ABB E6H5000 PR122/P-LSI 5000A 3-Pole Withdrawable Air Circuit Breaker Moving Part

Why Choose the ABB E6H5000 PR122/P-LSI 5000A Air Circuit Breaker?

The ABB 1SDA056996R1, extended product type E6H5000PR122/P-LSIIn=5000A3pWMP, is a high-current SACE Emax air circuit breaker moving part designed for protection and switching in demanding low-voltage electrical distribution systems. Part of the ABB SACE Emax E6H series, this three-pole withdrawable unit combines a 5000 A rated current with the PR122/P-LSI R5000 electronic overcurrent release.

The E6H5000 is engineered for major industrial, commercial and infrastructure power distribution applications where dependable overload and short-circuit protection is essential. Its PR122/P-LSI R5000 electronic trip unit provides long-time, short-time and instantaneous protection functions, helping protect cables, busbars, switchgear and connected equipment while supporting selective coordination within complex electrical distribution networks.

With a rated operational voltage of 690 V AC and rated ultimate and service short-circuit breaking capacities of 100 kA throughout its specified AC voltage range, the E6H5000 provides substantial fault-clearing capability. This version is a three-pole withdrawable moving part designed for use with a compatible SACE Emax fixed part and is fitted with four auxiliary change-over contacts plus circuit-breaker open/closed position indication.

Reliable Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E6H5000 provide switching and protection for high-capacity low-voltage distribution networks. With a rated current of 5000 A and substantial short-circuit performance, the E6H platform is particularly suited to main incoming supplies, large switchboards and industrial distribution systems where significant electrical loads and prospective fault currents must be safely managed.

The PR122/P-LSI electronic release provides three complementary protection functions. Long-time protection responds to sustained overload conditions, short-time protection supports selective coordination between protective devices, and instantaneous protection provides rapid interruption during severe short-circuit faults. The withdrawable construction allows the circuit-breaker moving part to be disconnected and removed from its compatible fixed section, supporting inspection, servicing and replacement within critical high-current switchgear installations.

Typical Applications

• Main low-voltage electrical distribution switchboards.
• High-current industrial power distribution systems.
• Large switchgear and busbar assemblies.
• Transformer secondary protection and distribution.
• Generator and installation protection.
• Manufacturing and heavy process plants.
• Data centre and critical infrastructure power distribution.
• High-capacity switchgear requiring withdrawable selective LSI protection.
