Why Choose the ABB E3V800 PR122/P-LSI 800A 3P Fixed Air Circuit Breaker?
The ABB E3V800 PR122/P-LSI, order code 1SDA056532R1, is a high-performance SACE Emax air circuit breaker designed for protection and switching in demanding low-voltage power distribution systems. This three-pole fixed breaker uses the E3V 800 A configuration and is equipped with the PR122/P-LSI R800 electronic overcurrent release.
The PR122/P-LSI release provides long-time, short-time and instantaneous overcurrent protection. These LSI functions help protect electrical conductors, switchboards and connected equipment against sustained overloads and short-circuit faults, while the short-time protection function supports selective coordination in appropriately engineered distribution systems.
This version is supplied in a fixed configuration with rear horizontal terminals and is fitted with four auxiliary contacts together with circuit-breaker open/closed position indication. The E3V performance level is intended for demanding applications where high fault-interruption capability and configurable electronic protection are required.
