Why Choose the ABB PR221DS-LS/I 1SDA060363R1 Electronic Trip Unit?
The ABB 1SDA060363R1 is a PR221DS-LS/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 overload and short-circuit protection for high-current industrial and commercial low-voltage power distribution systems.
The PR221DS-LS/I provides long-time overload protection together with selectable short-circuit protection functionality. Its LS/I designation allows the release to support protection strategies using short-time or instantaneous response characteristics, helping coordinate the associated Tmax T6 breaker with other protective devices in the distribution network.
Designed specifically for the Tmax T6 800 platform, the 1SDA060363R1 is supplied as a loose or configurable electronic release for a three-pole AC circuit breaker. Its 800 A rating and adjustable short-circuit release range make it suitable for maintaining, configuring or replacing the protection unit in compatible T6 installations.

How Does the ABB PR221DS-LS/I Electronic Trip Unit Work?
An electronic trip unit monitors current through the associated circuit breaker and commands the breaker to open when current conditions exceed the configured protection thresholds. The PR221DS-LS/I combines long-time overload protection with selectable short-circuit protection characteristics, providing a configurable electronic alternative to conventional thermomagnetic protection.
For the Tmax T6 800 platform, this 800 A three-pole release can be used as part of a coordinated protection system for high-current feeders and distribution circuits. Its adjustable short-circuit release range of 800–8000 A allows the protection response to be matched more closely to the requirements of the installation and associated protective devices.
Typical Applications
- ABB SACE Tmax T6 800 circuit-breaker assemblies.
- Industrial low-voltage power distribution systems.
- Main and sub-main feeder protection.
- High-current three-phase distribution circuits.
- Switchboards requiring configurable electronic overload and short-circuit protection.
- Replacement or maintenance of compatible PR221DS-LS/I-equipped Tmax T6 breakers.
