Why Choose the ABB PR221DS-I In=630 T6 630 3P 1SDA060352R1 Trip Unit?
The ABB PR221DS-I In=630 T6 630 3P 1SDA060352R1 is a three-pole solid-state electronic trip unit designed for compatible ABB SACE Tmax T6 630 moulded case circuit breakers. With a rated current of 630 A, this PR221DS-I release provides 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 configured instantaneous fault-current threshold is exceeded. The I-only protection characteristic makes this version suitable for applications where instantaneous short-circuit protection is required without the long-time overload function provided by other PR221DS variants.
This release is specifically configured for T6 630 three-pole circuit breakers and has a rated current of 630 A. Its undelayed short-circuit release is adjustable from 630–6300 A, corresponding to 1–10 × In, providing flexibility when coordinating instantaneous protection with the characteristics of the electrical installation.

Instantaneous Electronic Protection for Tmax T6 Circuit Breakers
Electronic trip units such as the ABB PR221DS-I monitor current through a compatible circuit breaker and initiate tripping when the selected instantaneous short-circuit threshold is exceeded. This provides rapid interruption of high fault currents and helps protect electrical equipment and distribution circuits against the damaging thermal and mechanical effects of short circuits.
For this 630 A T6 configuration, the instantaneous protection threshold can be adjusted across a broad 630–6300 A range. This allows engineers to coordinate the trip characteristic with the requirements of the installation while using the proven modular architecture of the ABB SACE Tmax T6 circuit-breaker platform.
Typical Applications
- Compatible ABB SACE Tmax T6 630 moulded case circuit breakers.
- Industrial low-voltage power distribution systems.
- Electrical switchboards and distribution panels.
- High-current industrial feeder circuits.
- Manufacturing and process plant electrical systems.
- Applications requiring adjustable instantaneous short-circuit protection.
