Why Choose the ABB E6V 6300 PR121/P-LI 6300A 3P Fixed Air Circuit Breaker?
The ABB E6V 6300 PR121/P-LI, order code 1SDA057136R1, is a high-capacity three-pole fixed air circuit breaker (ACB) designed for protection and switching in demanding low-voltage power distribution systems. Part of the ABB SACE Emax E6 series, it combines a rated uninterrupted current of 6300 A with the PR121/P-LI R6300 electronic overcurrent release.
The E6V performance level is intended for installations with exceptionally high prospective short-circuit currents. This breaker provides a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC, 50 Hz, while its PR121/P-LI electronic release provides long-time overload and instantaneous short-circuit protection.
This configuration is a three-pole fixed circuit breaker equipped with rear horizontal terminals. Four auxiliary change-over contacts and open/closed circuit-breaker position indication support status monitoring and integration into high-current switchboards, power distribution centres and critical electrical installations.
