1SDA057165R1 ABB E6V 6300 PR122/P-LSIG 6300A 4P Withdrawable Air Circuit Breaker

Why Choose the ABB E6V 6300 PR122/P-LSIG 6300A 4P Withdrawable Air Circuit Breaker?

The ABB E6V 6300 PR122/P-LSIG, order code 1SDA057165R1, is a high-performance SACE Emax air circuit breaker designed for protection, switching and isolation in high-current low-voltage electrical distribution systems. This four-pole E6V circuit breaker moving part has a rated current of 6300 A and incorporates ABB's advanced PR122/P-LSIG electronic overcurrent release.

Part of the ABB SACE Emax range, the E6V combines high short-circuit performance with electronic protection for demanding industrial and infrastructure applications. The PR122/P-LSIG trip unit provides long-time, short-time, instantaneous and earth-fault protection functions, helping protect conductors, switchgear and connected equipment against overloads and fault currents.

This model is supplied in a four-pole withdrawable configuration and is designed for rated operational voltages up to 690 V AC. It is fitted with four auxiliary contacts and circuit-breaker open/closed position indication, providing useful status information for switchboard control and monitoring systems.

Reliable Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E6V provide controlled switching and protection of high-current electrical distribution circuits. The electronic trip unit continuously monitors circuit conditions and initiates tripping when configured protection thresholds are exceeded, helping minimise damage caused by overloads, short circuits and earth faults.

The PR122/P-LSIG release provides adjustable electronic protection suited to selective and coordinated low-voltage distribution systems. Combined with the withdrawable Emax architecture, this makes the E6V particularly suitable for main incoming, bus-coupler and high-current feeder applications where dependable protection and maintainability are essential.

Typical Applications

• Main incoming circuit protection in low-voltage switchboards.
• Industrial power distribution and process plants.
• Transformer and generator distribution systems.
• High-current feeder and bus-coupler protection.
• Commercial and infrastructure electrical distribution.
• Power generation and utility installations.
