Why Choose the ABB PR221DS-LS/I In=800 T6 800 4P 1SDA060369R1 Trip Unit?
The ABB PR221DS-LS/I In=800 T6 800 4P 1SDA060369R1 is a four-pole electronic trip unit designed for compatible ABB SACE Tmax T6 800 moulded case circuit breakers. With a rated current of 800 A, the PR221DS-LS/I provides adjustable overload and short-circuit protection for demanding low-voltage industrial power distribution applications.
As part of the ABB SACE Tmax T6 protection system, the PR221DS-LS/I provides long-time overload protection together with short-circuit protection. Its electronic protection characteristics allow the circuit breaker response to be adapted to the requirements of the protected circuit, supporting effective coordination with cables, loads and other protective devices within an electrical distribution system.
This version is specifically configured for T6 800 four-pole circuit breakers and has a rated current of 800 A. The long-time protection threshold is adjustable from 0.4–1 × In, corresponding to 320–800 A, while the instantaneous short-circuit threshold extends from 1–10 × In, corresponding to 800–8000 A.

Adjustable Electronic Protection for Tmax T6 Circuit Breakers
Electronic trip units such as the ABB PR221DS-LS/I monitor current through a compatible circuit breaker and initiate tripping when configured protection thresholds are exceeded. The long-time function protects against sustained overload conditions, while the short-circuit function responds to high fault currents that could otherwise cause severe thermal and mechanical damage to electrical equipment.
For this 800 A four-pole T6 configuration, the adjustable 320–800 A long-time range and 800–8000 A instantaneous short-circuit range provide flexibility when coordinating circuit protection with the requirements of an industrial electrical installation. The four-pole design makes the release suitable for compatible T6 800 circuit breakers used in three-phase four-wire distribution systems.
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.
- Main and sub-main electrical feeders.
- Electrical switchboards and distribution panels.
- Manufacturing and process plant electrical systems.
- Applications requiring adjustable overload and short-circuit protection.
