Why Choose the ABB PR221DS-I 1SDA060364R1 Electronic Trip Unit?
The ABB 1SDA060364R1 is a PR221DS-I three-pole electronic trip unit designed for compatible ABB SACE Tmax T6 800 moulded-case circuit breakers. Rated at 800 A, it provides electronic short-circuit protection for high-current industrial and commercial low-voltage power distribution applications.
The PR221DS-I configuration provides an instantaneous short-circuit protection function, allowing the associated Tmax T6 circuit breaker to open rapidly when current rises above the configured fault threshold. Its undelayed short-circuit release setting range extends from 800–8000 A, providing adjustment to suit the protection requirements of the installation.
Designed specifically for the Tmax T6 800 platform, the 1SDA060364R1 is a three-pole AC solid-state release suitable for compatible power circuit breakers. It is particularly useful when configuring, maintaining or replacing the electronic protection release in a T6 800 assembly requiring instantaneous short-circuit protection.

- Designed for compatible AC power circuit-breaker applications.
How Does the ABB PR221DS-I Electronic Trip Unit Work?
An instantaneous electronic trip unit monitors current through the associated circuit breaker and initiates tripping when the current exceeds its configured short-circuit threshold. Unlike protection functions incorporating an intentional time delay, the instantaneous I function is intended to react rapidly to severe short-circuit conditions, helping limit the duration of high fault currents within the protected electrical system.
On the ABB PR221DS-I In=800, the undelayed short-circuit release can be adjusted from 800–8000 A. This adjustable range allows the protection threshold to be selected according to the characteristics of the T6 800 installation and its protection-coordination requirements while retaining the rapid response associated with instantaneous short-circuit protection.
Typical Applications
- ABB SACE Tmax T6 800 circuit-breaker assemblies.
- Industrial low-voltage power distribution systems.
- High-current three-phase distribution circuits.
- Circuits requiring adjustable instantaneous short-circuit protection.
- Switchboard and power circuit-breaker protection configurations.
- Replacement or maintenance of compatible PR221DS-I-equipped Tmax T6 breakers.
