Why Choose the ABB PR222DS/PD-LSI 1SDA060373R1 Electronic Trip Unit?
The ABB 1SDA060373R1 is a PR222DS/PD-LSI four-pole electronic trip unit designed for compatible ABB SACE Tmax T6 800 moulded-case circuit breakers. Rated at 800 A, it provides configurable electronic protection for demanding high-current industrial and commercial low-voltage power distribution systems.
The PR222DS/PD-LSI provides long-time, short-time and instantaneous protection functions. This LSI configuration enables the associated Tmax T6 circuit breaker to protect against sustained overloads, delayed short-circuit conditions and severe instantaneous faults, while electronic settings support effective coordination with conductors and other protective devices.
The PD version incorporates communication functionality, enabling integration with compatible ABB monitoring, supervision and power-management architectures. Its four-pole configuration makes the release suitable for compatible three-phase four-wire T6 800 breaker assemblies where protection of the neutral pole is required as part of the selected system design.

How Does the ABB PR222DS/PD-LSI Electronic Trip Unit Work?
An electronic trip unit monitors current through the associated circuit breaker and initiates tripping when configured protection thresholds and timing conditions are exceeded. The LSI functions provide long-time protection against sustained overloads, short-time delayed protection for coordinated short circuits and instantaneous protection for severe faults requiring rapid interruption.
The PR222DS/PD version combines these electronic protection functions with communication capability. When installed in a compatible Tmax T6 800 four-pole circuit breaker, the 1SDA060373R1 provides an integrated solution for high-current circuit protection and connection to compatible ABB monitoring or power-management systems.
Typical Applications
- ABB SACE Tmax T6 800 four-pole circuit-breaker assemblies.
- Industrial low-voltage power distribution systems.
- Three-phase four-wire distribution networks.
- Main and sub-main feeder protection.
- Switchboards requiring electronic LSI protection and communication capability.
- Replacement or maintenance of compatible PR222DS/PD-equipped Tmax T6 breakers.
