1SDA058061R1 ABB E6H-A 5000 PR122/P-LSIG 5000 A 3-Pole Withdrawable Air Circuit Breaker Moving Part

Why Choose the ABB E6H-A 5000 PR122/P-LSIG Air Circuit Breaker?

The ABB E6H-A 5000 PR122/P-LSIG, order code 1SDA058061R1, is a high-performance SACE Emax air circuit breaker moving part designed for demanding high-current low-voltage electrical distribution systems. This three-pole withdrawable unit has a 5000 A rated current and combines the robust E6H-A frame with ABB's PR122/P-LSIG electronic overcurrent release.

The PR122/P-LSIG trip unit provides comprehensive long-time, short-time, instantaneous and ground-fault protection, helping protect electrical installations against overloads, short circuits and earth faults. An R5000 rating plug complements the 5000 A configuration, making the breaker suitable for major distribution circuits where advanced electronic protection is required.

The 1SDA058061R1 is supplied as a three-pole withdrawable moving part with an Im 75,000 A instantaneous protection designation. It is also fitted with four auxiliary contacts and circuit-breaker open/closed position indication, providing useful status information when integrated into a compatible SACE Emax withdrawable circuit-breaker assembly.

Advanced Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E6H-A provide switching and overcurrent protection for high-capacity low-voltage distribution circuits. A 5000 A breaker is suited to substantial electrical systems where large loads and high current levels demand robust switching equipment, including main distribution boards and major industrial power networks.

The PR122/P-LSIG electronic release combines four important protection functions. Long-time protection responds to sustained overload conditions, short-time and instantaneous functions provide protection against short circuits, and ground-fault protection addresses earth-fault conditions. The withdrawable construction of the 1SDA058061R1 also supports inspection and maintenance when installed with the appropriate SACE Emax fixed part.

Typical Applications

• Main low-voltage electrical switchboards.
• High-current industrial power distribution systems.
• Large manufacturing and process facilities.
• Commercial and infrastructure electrical distribution.
• Power generation and utility distribution equipment.
• Large plant and facility distribution systems.
• High-capacity feeders requiring electronic LSIG protection.
