1SDA060793R1 ABB E3H-A 800 PR121/P-LSI 800 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB 1SDA060793R1 E3H-A 800 Withdrawable Air Circuit Breaker?

The ABB 1SDA060793R1 is a SACE Emax E3H-A 800 withdrawable air circuit breaker moving part designed for switching and protection in demanding low-voltage power distribution systems. Identified as E3H-A 800 PR121/P-LSI 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 E3H-A is engineered for switchboards requiring dependable electronic overload and short-circuit protection. Its PR121/P-LSI trip unit provides long-time, short-time and instantaneous protection functions, supporting coordinated protection of electrical distribution circuits and connected equipment.

This version features a withdrawable moving-part construction for use with a compatible Emax E3 fixed part. The breaker incorporates an R800 overcurrent release with a 12000 A instantaneous release reference, three-pole construction, four auxiliary contacts and open/closed position indication, while its withdrawable design supports efficient inspection, servicing and replacement.

Advanced Withdrawable Protection for Low-Voltage Distribution

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

The PR121/P-LSI electronic trip unit gives the ABB 1SDA060793R1 long-time, short-time and instantaneous protection functions for coordinated overload and short-circuit protection. Combined with its 800 A three-pole withdrawable construction, R800 release and auxiliary signalling contacts, it provides a practical solution for professional industrial, commercial and infrastructure low-voltage distribution systems.

Typical Applications

• Industrial low-voltage switchboards.
• Main and sub-main electrical distribution systems.
• Withdrawable air circuit-breaker installations.
• Manufacturing and process plants.
• Commercial and infrastructure power distribution.
• Engineered low-voltage switchgear assemblies.
