Why Choose the ABB PR222DS/P-LSI In=400 T5 4-Pole Electronic Trip Unit?
The ABB 1SDA054704R1 is a PR222DS/P-LSI electronic trip unit with a rated current of 400 A, designed for use with four-pole ABB SACE Tmax T5 moulded-case circuit breakers. Part of the ABB Tmax T4–T8 product family, it provides advanced electronic overload and short-circuit protection for industrial and commercial low-voltage power distribution systems.
The PR222DS/P platform provides LSI protection functions, covering long-time overload, short-time short-circuit and instantaneous short-circuit protection. Electronic current sensing enables accurate and repeatable protection characteristics, while adjustable settings allow the trip unit to be coordinated with upstream and downstream protective devices.
With a rated current of 400 A and a four-pole configuration, the PR222DS/P-LSI is well suited to three-phase and neutral distribution systems using the ABB Tmax T5 platform. Its adjustable short-circuit protection range supports effective selectivity and protection coordination in switchboards, feeders and industrial distribution installations.

Advanced Electronic Protection for Power Distribution
Electronic trip units monitor circuit current and command the circuit breaker to open when configured protection thresholds are exceeded. The PR222DS/P-LSI combines long-time, short-time and instantaneous functions to protect against sustained overloads as well as different levels of short-circuit current.
The adjustable protection characteristics of the PR222DS/P platform make it suitable for coordinated low-voltage distribution systems. By tailoring the trip response to the installation, engineers can improve selectivity between protective devices while maintaining dependable protection for conductors, equipment and downstream circuits.
