1SDA060859R1 ABB E3V-A 800 PR121/P-LSIG 800 A 3-Pole Fixed Air Circuit Breaker

Why Choose the ABB 1SDA060859R1 E3V-A 800 Air Circuit Breaker?

The ABB 1SDA060859R1 is a high-performance SACE Emax E3V-A 800 air circuit breaker designed for switching and protection in demanding low-voltage power distribution systems. Identified as E3V-A 800 PR121/P-LSIG In=800A 3p F, this three-pole fixed circuit breaker combines an 800 A rated current with the ABB PR121/P electronic overcurrent release.

As part of the ABB SACE Emax range, the E3V-A offers high short-circuit performance for industrial switchboards and critical distribution systems. The PR121/P-LSIG electronic trip unit provides long-time, short-time, instantaneous and ground-fault protection functions, giving comprehensive protection against overload, phase short-circuit and earth-fault conditions.

This fixed three-pole version features horizontal rear terminals and an R800 overcurrent release with a 12000 A instantaneous release reference. The E3V-A 800 frame provides a 125 kA short-circuit current rating at 480 V and an 85 kA short-time current rating, making it suitable for installations requiring particularly high fault-current performance.

Advanced LSIG Protection for High-Fault-Level Distribution

Air circuit breakers such as the ABB SACE Emax E3V-A provide switching and protection for high-current low-voltage distribution circuits. The E3V-A performance level is particularly suited to switchboards where prospective short-circuit currents are high, with this 800 A frame providing a 125 kA short-circuit current rating at 480 V and an 85 kA short-time current rating.

The PR121/P-LSIG electronic trip unit adds ground-fault protection to the long-time, short-time and instantaneous functions. This combination allows the ABB 1SDA060859R1 to protect against sustained overloads, delayed and instantaneous short circuits, and ground-fault conditions, making it a comprehensive protection solution for demanding industrial and infrastructure low-voltage systems.

Typical Applications

• High-fault-level industrial low-voltage switchboards.
• Main and sub-main electrical distribution systems.
• Manufacturing and process plants.
• Large commercial building power distribution.
• Industrial plant and machinery distribution systems.
• Infrastructure and engineered low-voltage switchgear.
• Distribution systems requiring electronic ground-fault protection.
