1SDA057164R1 ABB E6V 6300 PR122/P-LSI 6300A 4P Withdrawable Air Circuit Breaker

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

The ABB 1SDA057164R1 is a high-performance SACE Emax E6V air circuit breaker moving part designed for protection and switching in demanding high-current low-voltage electrical distribution systems. Rated at 6300 A, this four-pole withdrawable breaker incorporates an ABB PR122/P-LSI R6300 electronic overcurrent release providing long-time overload, short-time delayed and instantaneous short-circuit protection.

Its four-pole configuration enables simultaneous switching of all four conductors in suitable three-phase systems with a neutral conductor. The withdrawable moving-part design is intended for use with the corresponding ABB SACE Emax fixed part, allowing isolation and removal of the breaker for inspection, servicing or replacement.

The E6V performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC. Combined with the advanced PR122/P-LSI trip unit, four auxiliary contacts and open/closed position indication, the 1SDA057164R1 provides a robust solution for critical high-capacity switchboards and power distribution networks.

Advanced Protection for High-Current Four-Pole Distribution

Air circuit breakers such as the ABB SACE Emax E6V provide switching and overcurrent protection for major low-voltage distribution circuits. The PR122/P electronic trip unit monitors current conditions and initiates circuit-breaker operation when configured overload or short-circuit thresholds are exceeded, helping protect busbars, cables, transformers and connected electrical equipment.

The PR122/P-LSI release combines long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection with the 6300 A capability of the E6V frame. Its four-pole and withdrawable configuration makes the breaker particularly suitable for high-capacity systems requiring neutral switching together with maintainable circuit-breaker installation.

Typical Applications

• Main incoming circuit breakers in high-current low-voltage switchboards.
• Four-pole three-phase distribution systems with neutral switching.
• Industrial power distribution systems.
• High-capacity feeder protection.
• Transformer secondary protection and switching.
• Manufacturing and process plants.
• Commercial and infrastructure power distribution.
• Switchboards requiring withdrawable 6300 A breakers with LSI protection.
