1SDA057152R1 ABB E6V6300 PR121/P-LI 6300A 3-Pole Withdrawable Air Circuit Breaker Moving Part

Why Choose the ABB E6V6300 PR121/P-LI 6300A 3-Pole Withdrawable Air Circuit Breaker?

The ABB 1SDA057152R1 is a high-performance SACE Emax E6V air circuit breaker moving part designed for switching and protection of very high-current low-voltage electrical distribution systems. Part of the ABB New Emax series, the E6V6300 combines a substantial 6300 A current rating with the PR121/P-LI electronic overcurrent release for dependable protection in demanding industrial, commercial and infrastructure power distribution applications.

This three-pole withdrawable circuit breaker moving part is equipped with the PR121/P-LI R6300 electronic trip unit. Its LI protection functions provide long-time overload (L) and instantaneous short-circuit (I) protection, helping protect distribution equipment against sustained overcurrents and severe short-circuit faults.

The E6V designation identifies the high short-circuit performance version of the E6 frame, with an ultimate short-circuit breaking capacity of 150 kA at 400 V AC, 50 Hz. Combined with its 6300 A current capability and withdrawable construction, the 1SDA057152R1 is suited to major power distribution systems where high fault-clearing performance and serviceable switchgear are required.
