Why Choose the ABB PR222DS/PD-LSIG 1SDA060374R1 Electronic Trip Unit?
The ABB 1SDA060374R1 is a PR222DS/PD-LSIG four-pole electronic trip unit designed for compatible ABB SACE Tmax T6 800 moulded-case circuit breakers. Rated at 800 A, it combines advanced electronic protection with communication capability 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 comprehensive protection and effective coordination within the electrical installation.
The PD version incorporates communication functionality for integration with compatible ABB monitoring and power-management architectures. Its four-pole configuration makes the release suitable for compatible three-phase four-wire T6 800 breaker assemblies, while its adjustable instantaneous short-circuit release range of 1200–8400 A provides flexibility when coordinating high-current distribution protection.

How Does the ABB PR222DS/PD-LSIG Electronic Trip Unit Work?
An electronic trip unit monitors current through the associated circuit breaker and commands the breaker to open when configured protection thresholds and timing conditions are reached. The LSIG functions provide long-time protection against sustained overloads, short-time delayed protection for coordinated short circuits, instantaneous protection against severe high-current faults and ground-fault protection for unintended current paths to earth.
The PR222DS/PD configuration adds communication capability to these electronic protection functions, allowing a compatible Tmax T6 installation to form part of a wider monitoring or power-management architecture. For the 1SDA060374R1, the combination of an 800 A rating, four-pole configuration, LSIG protection and an adjustable 1200–8400 A instantaneous short-circuit range makes it suitable for sophisticated high-current distribution applications.
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 requiring LSIG functionality.
- Switchboards requiring ground-fault protection and communication capability.
- Replacement or maintenance of compatible PR222DS/PD-LSIG-equipped Tmax T6 breakers.
