Why Choose the ABB 1SDA060603R1 PR221DS-I 1000A Trip Unit?
The ABB 1SDA060603R1 is a PR221DS-I electronic trip unit designed for ABB SACE Tmax T6 1000 circuit breaker configurations. Rated at 1000 A and specified for a four-pole arrangement, it provides electronic overcurrent protection when installed with a compatible Tmax T6 breaking part.
As part of the ABB SACE Tmax T6 protection system, the PR221DS-I monitors current and commands the circuit breaker to trip when its configured protection thresholds are exceeded. Its electronic design provides dependable overload and instantaneous short-circuit protection for high-current low-voltage distribution circuits.
The 1SDA060603R1 is supplied as a trip unit rather than a complete circuit breaker. It is intended to be combined with a compatible ABB Tmax T6 1000 breaking part, allowing the breaker body and protection unit to form a coordinated circuit protection assembly.

Electronic Protection for Tmax T6 1000 Circuit Breakers
An electronic trip unit continuously evaluates current flowing through a circuit breaker and initiates tripping when defined protection conditions are reached. Long-time protection responds to sustained overloads, while instantaneous protection reacts rapidly to high short-circuit currents, helping protect conductors and electrical equipment from damaging fault conditions.
The ABB 1SDA060603R1 provides these functions for a compatible four-pole Tmax T6 1000 assembly. By separating the protection release from the breaking part, the modular Tmax architecture allows the appropriate breaker performance level and trip-unit configuration to be combined for the requirements of the installation.
Typical Applications
- ABB Tmax T6 1000 circuit breaker assemblies.
- Industrial low-voltage power distribution.
- Four-pole main and sub-main feeders.
- Manufacturing and process plant switchboards.
- Commercial and infrastructure distribution systems.
- Maintenance and configuration of compatible Tmax T6 circuit breakers.
