Why Choose the ABB 1SDA054703R1 PR222DS/P-LSI 320 A T5 4P Electronic Trip Unit?
The ABB 1SDA054703R1 is a PR222DS/P-LSI electronic trip unit designed for four-pole ABB SACE Tmax T5 moulded-case circuit breakers. With a rated current of 320 A, it provides electronic long-time overload, selective short-circuit and instantaneous short-circuit protection for industrial and commercial low-voltage power distribution systems.
As part of the ABB SACE Tmax T5 protection platform, the PR222DS/P uses electronic protection technology to provide configurable and repeatable circuit protection. Its LSI protection functions allow the circuit breaker to respond appropriately to sustained overloads as well as short-circuit faults of different magnitudes.
The four-pole (4P) 1SDA054703R1 is rated at 320 A and is intended for compatible Tmax T5 circuit breakers. The PR222DS/P family is suitable for applications requiring more advanced protection and system integration than basic thermomagnetic releases, making it well suited to distribution boards, switchboards and industrial feeder circuits.

Advanced Electronic Protection for Power Distribution
Electronic trip units continuously evaluate circuit current and initiate operation of the associated circuit breaker when configured protection thresholds are exceeded. The ABB PR222DS/P-LSI combines long-time overload protection with selective and instantaneous short-circuit functions, helping protect conductors, switchgear and connected equipment against damaging overcurrent conditions.
The combination of L, S and I protection functions supports coordinated protection across low-voltage distribution systems. Installed in a compatible four-pole ABB SACE Tmax T5 circuit breaker, the 1SDA054703R1 provides a flexible electronic protection solution for feeders, switchboards and industrial power distribution networks.
