Why Choose the ABB 1SDA060729R1 E3S-A 3200 PR121/P-LSI Moving Part?
The ABB 1SDA060729R1, identified as E3S-A 3200 PR121/P-LSI In=3200A 3p W MP, is a three-pole moving part for a withdrawable SACE Emax E3S-A air circuit breaker. Designed for UL low-voltage power-distribution applications, it combines a substantial 3200 A rated current with ABB’s PR121/P electronic overcurrent release.
The fitted PR121/P-LSI trip unit provides long-time, short-time and instantaneous overcurrent protection. These LSI functions protect the connected distribution circuit against sustained overloads and short-circuit conditions, making the breaker suitable for demanding main and feeder protection duties.
As a withdrawable moving part, the 1SDA060729R1 is designed to interface with a compatible SACE Emax E3 fixed part installed in the switchboard. This architecture allows the breaker moving section to be withdrawn for isolation, inspection or maintenance while the fixed switchboard connections remain in place.

Reliable LSI Protection in Withdrawable Emax Switchgear
The withdrawable SACE Emax architecture separates the circuit-breaker moving part from the permanently installed fixed part. The ABB 1SDA060729R1 can therefore be withdrawn from a compatible E3 fixed part for maintenance, inspection or replacement without dismantling the principal switchboard power connections.
Its PR121/P-LSI electronic release provides long-time, short-time and instantaneous protection, while the 3200 A E3S-A platform provides substantial current-carrying capability. The combination of electronic protection, auxiliary contacts, position indication and withdrawable construction supports dependable operation and practical maintenance in high-current distribution switchgear.
Typical Applications
- Industrial low-voltage main distribution switchboards.
- ABB SACE Emax E3S-A withdrawable circuit-breaker installations.
- High-current main incoming protection.
- High-capacity feeder protection.
- Manufacturing and process-industry switchgear.
- Commercial and infrastructure power-distribution systems.
- UL switchboards requiring 3200 A LSI electronic protection.
