Why Choose the ABB 1SDA054642R1 PR222DS/PD-LSI Electronic Trip Unit?
The ABB 1SDA054642R1 is a PR222DS/PD-LSI electronic trip unit designed for use with four-pole ABB SACE Tmax T4 moulded-case circuit breakers. Rated at 160 A, it combines electronic LSI protection with integrated Modbus RTU communication for power distribution, industrial control and automation applications.
As part of the ABB Tmax T protection system, the PR222DS/PD provides overload (L), selective short-circuit (S) and instantaneous short-circuit (I) protection. Protection parameters can be configured through the trip unit, while its electronic architecture supports accurate protection and monitoring within compatible Tmax T4 installations.
The integrated communication unit allows the circuit breaker to be incorporated into a Modbus RTU network using an EIA RS-485 physical interface. Communication operates at speeds up to 19.2 kbps and requires a 24 V DC auxiliary supply, enabling connection with PLCs, PCs and compatible supervision or automation systems.

Electronic Protection and Modbus Communication
The ABB PR222DS/PD combines electronic circuit protection with communication capabilities for intelligent low-voltage distribution systems. Its LSI functions protect against overload and short-circuit conditions, while the protection section is powered from the trip unit current transformers so that protective tripping does not depend on the communication auxiliary supply.
Integrated Modbus RTU communication enables compatible Tmax T4 circuit breakers to participate in industrial supervision and automation networks. With the required 24 V DC auxiliary supply, operating information and protection parameters can be communicated remotely, supporting more effective monitoring and management of electrical distribution equipment.
Typical Applications
- ABB SACE Tmax T4 moulded-case circuit breaker installations.
- Industrial low-voltage power distribution systems.
- Electrical switchboards and distribution panels.
- Modbus-connected circuit protection systems.
- PLC and supervisory control networks.
- Industrial automation and power monitoring systems.
