1SDA056531R1 ABB E3V800 PR122/P-LI 800A 3P Fixed Air Circuit Breaker

Why Choose the ABB E3V800 PR122/P-LI 800A 3P Fixed Air Circuit Breaker?

The ABB E3V800 PR122/P-LI, order code 1SDA056531R1, is a high-performance SACE Emax air circuit breaker designed for protection and switching in demanding low-voltage power distribution systems. Part of the ABB SACE Emax E3V series, this three-pole fixed circuit breaker has a rated uninterrupted current of 800 A and incorporates the PR122/P-LI R800 electronic overcurrent release.

The PR122/P-LI release provides long-time and instantaneous overcurrent protection, helping protect conductors, switchboards and connected equipment against sustained overloads and severe short-circuit faults. Its adjustable overload setting allows the protection to be configured within the requirements of the installation, while the E3V breaker provides very high fault-interruption performance.

This version is a fixed three-pole circuit breaker with rear horizontal terminals and is fitted with four change-over auxiliary contacts together with circuit-breaker open/closed position indication. With a rated voltage of 690 V AC and a rated ultimate short-circuit breaking capacity of 130 kA at 400 V AC, 50 Hz, the E3V800 is well suited to critical industrial and infrastructure distribution systems.
