Why Choose the ABB PR221DS-I In=1000 T6 1000 3P 1SDA060597R1 Electronic Trip Unit?
The ABB PR221DS-I In=1000 T6 1000 3P 1SDA060597R1 is a three-pole solid-state electronic trip unit designed for compatible ABB SACE Tmax T6 1000 moulded case circuit breakers. With a rated current of 1000 A, it provides instantaneous short-circuit protection for high-current AC power distribution applications.
The PR221DS-I configuration is focused on instantaneous protection, using an adjustable undelayed short-circuit release range from 1000–10000 A. This allows the instantaneous trip threshold to be matched to the protection requirements of the compatible T6 1000 circuit-breaker assembly.
Designed as a modular protection component rather than a complete circuit breaker, the 1SDA060597R1 installs with a compatible ABB SACE Tmax T6 1000 three-pole breaking part. Its electronic operation provides a dedicated protection solution where instantaneous short-circuit response is required without the additional LSIG functions found on more advanced Tmax trip units.

Dedicated Instantaneous Protection for ABB Tmax T6 1000
The PR221DS-I is intended for applications where the required electronic protection function is instantaneous response to high short-circuit currents. Its adjustable threshold extends from 1000 A to 10000 A, equivalent to 1–10 times the 1000 A rated current, allowing the protection setting to be coordinated with the characteristics of the connected distribution circuit.
As part of ABB's modular SACE Tmax architecture, the trip unit works with a compatible T6 1000 breaking part to create the required circuit-breaker configuration. This separation between the breaking section and electronic protection unit enables the appropriate protection release to be selected for the application while retaining the mechanical and interruption capabilities of the corresponding Tmax T6 breaker.
Typical Applications
- Compatible ABB SACE Tmax T6 1000 circuit breakers.
- High-current industrial power distribution.
- Three-phase feeder protection.
- Manufacturing and process plant switchboards.
- Main and sub-main low-voltage distribution systems.
- Commercial and infrastructure electrical distribution.
- Applications requiring adjustable instantaneous short-circuit protection.
- Tmax T6 breaker configuration and replacement projects.
