Why Choose the ABB PR222DS/PD-LSIG 1SDA060356R1 Electronic Trip Unit?
The ABB 1SDA060356R1 is a PR222DS/PD-LSIG three-pole electronic trip unit designed for compatible ABB SACE Tmax T6 630 moulded-case circuit breakers. Rated at 630 A, it provides comprehensive electronic protection for demanding industrial and commercial low-voltage power distribution systems.
The PR222DS/PD-LSIG provides long-time, short-time, instantaneous and ground-fault protection functions. This LSIG configuration enables the associated Tmax T6 circuit breaker to respond to sustained overloads, delayed short-circuit conditions, severe instantaneous faults and ground faults, supporting effective protection coordination throughout the electrical installation.
The PD version incorporates communication functionality, allowing the electronic release to be integrated with compatible ABB supervision and power-management architectures. Combining 630 A capacity, three-pole operation, LSIG protection and communication capability, the 1SDA060356R1 is suited to applications requiring advanced circuit protection and enhanced system visibility.

How Does the ABB PR222DS/PD-LSIG Electronic Trip Unit Work?
An electronic trip unit monitors electrical current through the associated circuit breaker and commands the breaker to trip when configured protection thresholds and timing conditions are reached. The LSIG functions provide long-time protection against sustained overloads, short-time protection for coordinated short circuits, instantaneous protection for severe faults and ground-fault protection for current flowing through unintended earth paths.
The PR222DS/PD configuration extends these protection functions with communication capability, enabling compatible monitoring and supervision systems to interact with the protection architecture. This combination makes the 1SDA060356R1 particularly useful in Tmax T6 630 installations where comprehensive LSIG protection and communication functionality are required.
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 LSIG protection.
- Distribution systems requiring ground-fault protection and communication capability.
- Replacement or maintenance of compatible PR222DS/PD-equipped Tmax T6 breakers.
