1SDA055581R1 ABB E6H/f 5000 PR122/P-LSIG 5000A 4-Pole Withdrawable Air Circuit Breaker Moving Portion

Why Choose the ABB E6H/f 5000 PR122/P-LSIG 5000A 4-Pole Withdrawable Air Circuit Breaker Moving Portion?

The ABB E6H/f 5000 PR122/P-LSIG, order code 1SDA055581R1, is the withdrawable moving portion of an ABB SACE Emax E6H air circuit breaker. Rated at 5000 A, this four-pole configuration combines the high-performance E6H frame with a PR122/P-LSIG R5000 electronic overcurrent release for comprehensive protection of demanding low-voltage power distribution systems.

This moving portion features a full-size neutral and is designed for use with the appropriate fixed part of an ABB SACE Emax withdrawable circuit breaker assembly. It is fitted with four auxiliary contacts and open/closed position indication, supporting circuit breaker status signalling and integration with switchboard monitoring and control systems.

The PR122/P-LSIG release provides long-time, short-time, instantaneous and ground-fault protection. With a rated operational voltage of 690 V AC, 100 kA Icu and Ics at 415 V AC and high short-time withstand capability, this E6H configuration is suited to critical high-current distribution networks with substantial prospective fault levels.

Comprehensive PR122/P-LSIG Protection for 5000A Distribution

The ABB E6H 5000 platform is designed for major low-voltage circuits where very high continuous-current capacity and substantial short-circuit performance are required. As a withdrawable moving portion, 1SDA055581R1 is designed for use with the corresponding fixed part, providing a practical architecture for circuit breaker isolation, inspection and maintenance in critical switchgear installations.

The PR122/P-LSIG R5000 electronic release combines long-time overload protection, short-time protection for coordinated fault clearance, instantaneous protection for severe short circuits and ground-fault protection for earth-fault conditions. Together with the E6H frame's 100 kA ultimate and service breaking capacity at 415 V AC, it provides comprehensive protection for high-power distribution networks.

Typical Applications

• Main incomers in high-current low-voltage switchboards.
• Industrial power distribution systems.
• High-power feeder circuits.
• Withdrawable switchgear assemblies.
• Bus coupler and bus-section applications.
• Manufacturing and process plants.
• Large commercial and infrastructure facilities.
• High-fault-level low-voltage distribution networks.
