Why Choose the ABB 1SDA060821R1 E3H-A 3200 PR121/P-LI Moving Part?
The ABB 1SDA060821R1, identified as E3H-A 3200 PR121/P-LI In=3200A 3p W MP, is a three-pole moving part for a withdrawable SACE Emax E3H-A air circuit breaker. Designed for demanding 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-LI electronic trip unit uses an R3200 rating plug and provides long-time overload protection together with instantaneous short-circuit protection. This configuration is specified with an Im value of 48,000 A, providing rapid response to severe short-circuit conditions while retaining electronic long-time protection for sustained overloads.
As a withdrawable moving part, the 1SDA060821R1 is designed to operate with the appropriate SACE Emax E3 fixed part installed in the switchboard. The removable architecture supports isolation, inspection and servicing of the breaker while allowing the fixed portion of the withdrawable installation to remain mounted within the switchboard.
Key Advantages
- Genuine ABB SACE Emax E3H-A moving part for withdrawable circuit-breaker installations.
- 3200 A rated current for high-current low-voltage distribution.
- PR121/P-LI electronic overcurrent release for overload and instantaneous short-circuit protection.
- R3200 rating plug matched to the breaker’s rated current.
- 48,000 A Im value for instantaneous protection against severe fault currents.
- Three-pole UL configuration for compatible power-distribution systems.
- Withdrawable construction supports efficient isolation, inspection and maintenance.
- Fitted with 4 auxiliary contacts and circuit-breaker open/closed position indication.

Reliable LI Protection in Withdrawable Emax Switchgear
The ABB SACE Emax withdrawable architecture separates the removable circuit-breaker moving part from the fixed portion installed in the switchboard. The 1SDA060821R1 can therefore be withdrawn from a compatible E3 fixed part when isolation, inspection, servicing or replacement is required, supporting maintainable high-current switchboard designs.
Its PR121/P-LI electronic release provides long-time protection against sustained overload conditions and instantaneous protection against severe short circuits. Combined with the 3200 A E3H-A platform, R3200 rating plug, auxiliary contacts and withdrawable construction, this configuration provides a robust protection solution for demanding low-voltage distribution systems.
Typical Applications
- Industrial low-voltage main distribution switchboards.
- ABB SACE Emax E3H-A withdrawable circuit-breaker installations.
- High-current main incoming circuit protection.
- High-capacity feeder protection.
- Manufacturing and process-industry switchgear.
- Commercial and infrastructure power-distribution systems.
- UL switchboards requiring 3200 A LI electronic overcurrent protection.
