Why Choose the ABB 1SDA060773R1 E3S-A 800 Air Circuit Breaker?
The ABB 1SDA060773R1 is a SACE Emax E3S-A 800 air circuit-breaker moving part designed for dependable protection and switching in demanding low-voltage power distribution systems. This three-pole withdrawable breaker combines an 800 A rated current with ABB's PR122/P-LSI electronic overcurrent release, providing long-time, short-time and instantaneous overcurrent protection.
Configured as a three-pole withdrawable breaker, the 1SDA060773R1 is designed for use with a compatible ABB E3 fixed part. The withdrawable architecture allows the breaker moving section to be inserted, isolated and removed from the switchboard, supporting efficient inspection, servicing and replacement without dismantling the principal fixed power connections.
The PR122/P-LSI R800 trip unit provides adjustable electronic protection for coordinating the breaker with other protective devices in the electrical distribution system. Combined with the established E3 frame and S performance level, this configuration provides a versatile protection platform for industrial, commercial and infrastructure switchgear requiring a serviceable withdrawable breaker arrangement.
Key Advantages
- Genuine ABB SACE Emax E3S-A air circuit-breaker moving part.
- 800 A rated current for substantial low-voltage distribution loads.
- PR122/P-LSI electronic trip unit for comprehensive overcurrent protection.
- Long-time, short-time and instantaneous protection supports coordinated system protection.
- Three-pole withdrawable execution for serviceable switchgear installations.
- Designed for use with a compatible ABB E3 fixed part.
- Withdrawable construction simplifies breaker inspection, servicing and replacement.
- Part of ABB's established SACE Emax power distribution platform.
Key Features
- ABB SACE Emax E3S-A 800 circuit breaker.
- 800 A rated current.
- Three-pole (3P) configuration.
- Withdrawable (W) execution.
- Moving circuit-breaker section for a compatible E3 fixed part.
- PR122/P-LSI R800 electronic overcurrent release.
- Long-time (L) protection against sustained overload conditions.
- Short-time (S) protection for coordinated short-circuit protection.
- Instantaneous (I) protection against severe short-circuit currents.
- E3 frame with S performance level.
- Suitable for switchgear where breaker removal and isolation are required for servicing.
PR122/P-LSI Protection in a Withdrawable Emax Architecture
The ABB PR122/P-LSI electronic trip unit combines three important protection functions. The L function protects against sustained overloads, the S function provides short-time protection that supports selective coordination between protective devices, and the I function provides rapid instantaneous intervention during severe short-circuit conditions.
As a withdrawable circuit-breaker moving part, the 1SDA060773R1 is intended to operate with the corresponding compatible ABB E3 fixed portion rather than as a standalone fixed breaker. This arrangement allows the breaker to be disconnected and removed for inspection, servicing or replacement while the fixed portion and principal switchboard connections remain installed.
Typical Applications
- ABB SACE Emax E3 withdrawable switchgear installations.
- Main low-voltage power distribution switchboards.
- Industrial electrical distribution systems.
- Commercial and infrastructure main distribution boards.
- Manufacturing and process plant switchgear.
- Transformer secondary protection and distribution.
- Main incomer and feeder circuit-breaker applications.
- Switchgear requiring removable circuit breakers with coordinated electronic LSI protection.
