Why Choose the ABB PR221DS-LS/I In=630 T6 630 3P 1SDA060351R1 Trip Unit?
The ABB PR221DS-LS/I In=630 T6 630 3P 1SDA060351R1 is a three-pole electronic trip unit designed for use with compatible ABB SACE Tmax T6 630 moulded case circuit breakers. Rated at 630 A, the PR221DS-LS/I provides adjustable overload and short-circuit protection for demanding low-voltage power distribution applications.
As part of the ABB SACE Tmax T6 protection system, the PR221DS-LS/I provides LS/I protection functionality. Its long-time overload protection can be adjusted to suit the protected circuit, while its short-circuit protection provides an adjustable threshold for effective protection against high fault currents. This makes the release suitable for coordinating circuit protection with cables, loads and other protective devices within an electrical distribution system.
The electronic release is designed for T6 630 three-pole circuit breakers and has a rated current of 630 A. The long-time protection threshold is adjustable from 0.4–1 × In, while the short-circuit protection threshold can be adjusted from 1–10 × In, corresponding to approximately 630–6300 A for this 630 A version.

Adjustable Electronic Protection for Tmax T6 Circuit Breakers
Electronic trip units such as the ABB PR221DS-LS/I monitor current through the circuit breaker and initiate tripping when configured protection thresholds are exceeded. This enables the circuit breaker to protect cables and electrical equipment against sustained overloads and damaging short-circuit currents while providing greater adjustment flexibility than a fixed protection characteristic.
For this 630 A T6 configuration, the adjustable protection settings allow engineers to coordinate the trip characteristics with the requirements of the electrical installation. The PR221DS-LS/I therefore provides a flexible protection solution for industrial feeders, distribution circuits and other applications using compatible ABB SACE Tmax T6 630 circuit breakers.
Typical Applications
- ABB SACE Tmax T6 630 moulded case circuit breakers.
- Industrial low-voltage power distribution systems.
- Main and sub-main electrical feeders.
- Electrical switchboards and distribution panels.
- Manufacturing and process plant electrical systems.
- Overload and short-circuit protection of industrial circuits.
