1SDA057162R1 ABB E6V 6300 PR121/P-LSIG 6300A 4-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E6V 6300 PR121/P-LSIG 6300A 4-Pole Withdrawable Air Circuit Breaker?

The ABB E6V 6300 PR121/P-LSIG, order code 1SDA057162R1, is a high-capacity 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 E6V series, this configuration combines a 6300 A rated current, four-pole construction and withdrawable execution with ABB's PR121/P electronic protection technology.

The breaker is equipped with a PR121/P-LSIG R6300 electronic overcurrent release, providing long-time, short-time, instantaneous and earth-fault protection functions. This comprehensive LSIG protection arrangement helps safeguard very high-current distribution circuits against sustained overloads, short circuits and earth faults in industrial, commercial and infrastructure power systems.

With a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 150 kA at 400 V AC, the E6V 6300 is engineered for demanding high-fault-level installations. Its withdrawable moving-part construction supports maintainability in compatible SACE Emax switchgear, while four auxiliary contacts and open/closed position indication facilitate integration with switchgear monitoring and control systems.

Reliable LSIG Protection for Very High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E6V provide switching, isolation and electronic protection for major low-voltage distribution circuits. The E6 frame supports very high operating currents, while the V performance class delivers the high short-circuit interruption capability required for installations with substantial prospective fault currents.

The PR121/P-LSIG electronic release provides long-time protection against sustained overloads, short-time protection for short-circuit conditions, instantaneous protection against severe faults and earth-fault protection. Combined with the 6300 A rating, four-pole configuration and withdrawable construction, these functions make the 1SDA057162R1 suitable for critical high-capacity distribution systems requiring comprehensive electronic protection and serviceable switchgear architecture.

Typical Applications

• Main low-voltage electrical distribution switchboards.
• Industrial manufacturing and process plants.
• Very high-current incomer and feeder protection.
• Power generation and infrastructure installations.
• Large commercial and industrial main distribution systems.
• High-fault-level withdrawable switchgear requiring comprehensive electronic LSIG protection.
