Why Choose the ABB 1SDA054696R1 PR222DS/P-LSI Trip Unit?
The ABB 1SDA054696R1 is a three-pole PR222DS/P-LSI electronic trip unit designed for use with ABB Tmax T5 moulded-case circuit breakers. Part of the ABB Tmax T4–T8 circuit-breaker range, this protection release provides electronic overload and short-circuit protection for industrial electrical distribution systems.
Designed for dependable circuit protection, the PR222DS/P-LSI combines long-time, short-time and instantaneous protection functions in a compact electronic release. These LSI protection functions enable the trip characteristics to be configured for the requirements of the electrical installation, helping protect cables, equipment and downstream circuits against overloads and short circuits.
With a rated current of 400 A and a three-pole configuration, the 1SDA054696R1 is specifically intended for compatible ABB Tmax T5 circuit breakers. Its adjustable instantaneous short-circuit protection range extends from 600–4800 A, providing flexibility when coordinating protection within industrial power distribution systems.

Reliable Electronic Protection for Power Distribution
Electronic trip units monitor current flowing through a circuit breaker and initiate tripping when electrical conditions exceed configured protection thresholds. Compared with basic fixed protection devices, an electronic release provides greater flexibility for coordinating overload and short-circuit protection throughout an electrical distribution system.
The ABB PR222DS/P-LSI provides long-time protection against sustained overload conditions, short-time protection for selective short-circuit coordination and instantaneous protection against high fault currents. Installed with a compatible Tmax T5 circuit breaker, it provides a robust protection solution for industrial switchboards, distribution panels and machinery power systems.
Typical Applications
- Industrial low-voltage power distribution systems.
- ABB Tmax T5 moulded-case circuit breakers.
- Electrical switchboards and distribution panels.
- Industrial machinery power supplies.
- Manufacturing and process installations.
- Overload and short-circuit protection for three-phase circuits.
