Why Choose the ABB E3V800 PR121/P-LI 800A 4P W MP Air Circuit Breaker?
The ABB E3V800 PR121/P-LI, order code 1SDA056552R1, is a high-performance SACE Emax air circuit breaker moving part designed for switching and protection in demanding low-voltage power distribution systems. This E3 V configuration combines an 800 A rated current, four-pole construction and a PR121/P-LI R800 electronic overcurrent release.
Supplied as a withdrawable moving part, the E3V800 is designed for use with a compatible E3 withdrawable fixed part, allowing the breaker to be isolated and withdrawn for inspection, servicing or replacement. It is equipped with four auxiliary contacts and open/closed position indication, supporting integration into industrial switchgear and control systems.
The breaker is rated for operation up to 690 V AC, with a rated insulation voltage of 1000 V and rated impulse withstand voltage of 12 kV. Its V performance level provides an ultimate short-circuit breaking capacity of up to 130 kA at 220–440 V AC and 100 kA at 500–690 V AC, making it suitable for installations with substantial prospective fault currents.
