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.
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.
