Why Choose the ABB PR222DS/P-LSI In=320 T4 320 3P?

The ABB PR222DS/P-LSI In=320 T4 320 3P, order code 1SDA054629R1, is an electronic protection release for ABB SACE Tmax T4 320 three-pole moulded case circuit breakers. Rated at 320 A, it provides electronic protection for power-distribution circuits as part of a compatible Tmax T4 circuit breaker assembly.

The PR222DS/P-LSI provides L long-time overload, S short-time short-circuit and I instantaneous short-circuit protection. These protection functions allow the release to respond to sustained overloads as well as short-circuit faults, supporting selective and coordinated protection within low-voltage distribution systems.

Designed for the Tmax T4 320 three-pole platform, the 1SDA054629R1 forms part of ABB's modular moulded case circuit breaker architecture. It is a protection release rather than a complete circuit breaker and is intended for combination with a compatible Tmax T4 breaking part to provide the required protection and fault-interruption functions.

Key Advantages

  • Genuine ABB SACE Tmax PR222DS/P-LSI electronic protection release.
  • 320 A rated current for Tmax T4 320 applications.

LSI Electronic Protection for ABB Tmax T4 320 Circuit Breakers

The ABB PR222DS/P-LSI provides a coordinated set of electronic protection functions for compatible Tmax T4 circuit breakers. The L function protects against sustained overload conditions, the S function provides short-time short-circuit protection for improved coordination with downstream devices, and the I function provides rapid response to severe short-circuit faults.

With a rated current of 320 A, the 1SDA054629R1 is matched to the three-pole Tmax T4 320 platform. When combined with a compatible ABB breaking part, it forms part of a complete MCCB assembly in which the PR222DS/P-LSI provides electronic overcurrent protection and the selected breaking unit provides the required switching and fault-interruption performance.

Typical Applications

  • ABB SACE Tmax T4 320 moulded case circuit breaker assemblies.
  • Industrial low-voltage distribution switchboards.
  • Main and sub-distribution feeders.
  • Three-phase power-distribution circuits.
  • Applications requiring coordinated overload and short-circuit protection.
  • Manufacturing and process plant electrical systems.
  • Commercial and infrastructure power distribution.
