1SDA060861R1 ABB E3V-A 800 PR121/P-LSIG 800 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB 1SDA060861R1 E3V-A 800 Withdrawable Air Circuit Breaker?

The ABB 1SDA060861R1 is a high-performance SACE Emax E3V-A 800 withdrawable air circuit breaker moving part designed for switching and protection in demanding low-voltage power distribution systems. Identified as E3V-A 800 PR121/P-LSIG In=800A 3p W, this three-pole 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 is engineered for switchboards requiring particularly high short-circuit performance. Its PR121/P-LSIG electronic trip unit provides long-time, short-time, instantaneous and ground-fault protection functions, supporting comprehensive protection against overloads, short circuits and earth-fault conditions.

This version features a withdrawable moving-part construction for use with a compatible Emax E3 fixed part. The E3V-A 800 frame provides a 125 kA short-circuit current rating at 480 V and an 85 kA short-time current rating, while the breaker incorporates an R800 overcurrent release, four auxiliary contacts and open/closed position indication.

Advanced Withdrawable LSIG Protection for High-Fault-Level Distribution

Withdrawable air circuit breakers provide switching and protection while allowing the breaker moving part to be separated from its stationary fixed part. This architecture simplifies inspection, servicing and replacement because the breaker can be removed without dismantling the main switchboard power connections associated with the fixed part.

The PR121/P-LSIG electronic trip unit gives the ABB 1SDA060861R1 long-time, short-time, instantaneous and ground-fault protection functions. Combined with its 800 A three-pole withdrawable construction, 125 kA short-circuit current rating at 480 V and 85 kA short-time current rating, it provides comprehensive protection for demanding industrial and infrastructure low-voltage distribution systems.

Typical Applications

• High-fault-level industrial low-voltage switchboards.
• Main and sub-main electrical distribution systems.
• Withdrawable air circuit-breaker installations.
• Manufacturing and process plants.
• Large commercial and infrastructure power distribution.
• Engineered low-voltage switchgear assemblies.
• Distribution systems requiring electronic ground-fault protection.
