Why Choose the ABB PR222DS/PD-LSI 1SDA060355R1 Electronic Trip Unit?
The ABB 1SDA060355R1 is a PR222DS/PD-LSI three-pole electronic trip unit designed for compatible ABB SACE Tmax T6 630 moulded-case circuit breakers. Rated at 630 A, it provides configurable electronic protection for demanding industrial and commercial low-voltage power distribution applications.
The PR222DS/PD-LSI provides long-time, short-time and instantaneous protection functions, enabling the associated Tmax T6 circuit breaker to respond to overload and short-circuit conditions. Its electronic design allows protection settings to be coordinated more precisely with conductors, loads and other protective devices than conventional fixed protection arrangements.
The PD version adds communication capability to the PR222DS platform, making this release suitable for installations where circuit protection is integrated with supervision, monitoring or communication systems. The unit is designed specifically for a three-pole T6 630 breaker configuration and has a rated current of 630 A.
Key Advantages
- Genuine ABB PR222DS/PD-LSI electronic trip unit for compatible Tmax T6 circuit breakers.
- 630 A rated current for T6 630 applications.
- LSI protection covering long-time, short-time and instantaneous fault conditions.
- Communication-enabled PD version for integration with compatible monitoring and supervision systems.
- Three-pole configuration for three-phase circuit protection.
- Electronic protection enables configurable settings for improved selectivity and system coordination.
Key Features
- ABB PR222DS/PD-LSI solid-state electronic release.
- Designed for ABB SACE Tmax T6 630 circuit breakers.
- 630 A rated current (In).
- Three-pole (3P) AC configuration.

- PD communication functionality for compatible circuit-breaker monitoring and control architectures.
How Does the ABB PR222DS/PD-LSI Electronic Trip Unit Work?
An electronic trip unit continuously evaluates current conditions through the associated circuit breaker and initiates tripping when configured protection thresholds are exceeded. The LSI functions provide long-time protection against sustained overloads, short-time protection for coordinated short-circuit conditions and instantaneous protection for severe faults requiring rapid interruption.
The PR222DS/PD version combines these protection functions with communication capability, allowing the protection system to form part of a compatible supervisory or power-management architecture. This makes the 1SDA060355R1 particularly suitable for Tmax T6 630 installations requiring both configurable electronic protection and communication functionality.
Typical Applications
- ABB SACE Tmax T6 630 circuit-breaker assemblies.
- Industrial low-voltage power distribution systems.
- Main and sub-main feeder protection.
- Switchboards requiring electronic LSI protection.
- Power distribution systems requiring communication-enabled circuit protection.
- Replacement or maintenance of compatible PR222DS/PD-equipped Tmax T6 breakers.
