Why Choose the ABB PR221DS-I In=800 T6 800 4P 1SDA060370R1 Trip Unit?
The ABB PR221DS-I In=800 T6 800 4P 1SDA060370R1 is a four-pole solid-state electronic trip unit designed for compatible ABB SACE Tmax T6 800 moulded case circuit breakers. Rated at 800 A, this PR221DS-I release provides adjustable instantaneous short-circuit protection for demanding low-voltage industrial power distribution applications.
As part of the ABB SACE Tmax T6 protection system, the PR221DS-I uses electronic current sensing to initiate circuit-breaker tripping when the selected undelayed short-circuit threshold is exceeded. Its I protection characteristic is intended for applications requiring instantaneous short-circuit protection, with the trip threshold adjustable to suit the protection and coordination requirements of the installation.
This version is specifically configured for T6 800 four-pole circuit breakers. The undelayed short-circuit release has an adjustment range from 800–8000 A, corresponding to 1–10 × In for the 800 A rated release, providing flexibility when coordinating high-current fault protection within industrial distribution systems.

Instantaneous Electronic Protection for Tmax T6 Circuit Breakers
The ABB PR221DS-I monitors current through a compatible circuit breaker and initiates tripping when the selected instantaneous short-circuit threshold is exceeded. This rapid response helps limit the damaging thermal and mechanical effects associated with high fault currents in industrial electrical distribution equipment.
For this 800 A four-pole T6 configuration, the adjustable 800–8000 A undelayed short-circuit range enables the protection threshold to be coordinated with the requirements of the installation. The four-pole configuration makes the release suitable for compatible T6 800 circuit breakers used in three-phase four-wire distribution arrangements.
Typical Applications
- Compatible ABB SACE Tmax T6 800 moulded case circuit breakers.
- Industrial low-voltage power distribution systems.
- Three-phase four-wire electrical distribution systems.
- High-current industrial feeder circuits.
- Electrical switchboards and distribution panels.
- Manufacturing and process plant electrical systems.
- Applications requiring adjustable instantaneous short-circuit protection.
