Why Choose the ABB PR222DS/PD-LSI In=100 MODBUS T4 4P?
The ABB PR222DS/PD-LSI In=100 MODBUS T4 4P, order code 1SDA054641R1, is an electronic protection and communication release for ABB SACE Tmax T4 four-pole moulded case circuit breakers. Rated at 100 A, it combines electronic overload and short-circuit protection with integrated Modbus RTU communication for connection to compatible supervision, control and automation systems.
The PR222DS/PD-LSI provides L long-time overload, S short-time short-circuit and I instantaneous short-circuit protection. In addition to these protection functions, the PD version incorporates an integrated dialogue unit using the Modbus RTU protocol over EIA RS-485, enabling a compatible Tmax T4 circuit breaker to exchange operating, measurement, alarm and status information with a supervisory system.
Designed for the ABB SACE Tmax T4 four-pole platform, the 1SDA054641R1 supports communication speeds up to 19,200 bit/s and uses a galvanically isolated 24 V DC ±20% auxiliary supply for its communication functionality. It is a protection release rather than a complete circuit breaker and is intended for integration with a compatible Tmax T4 breaking unit.

LSI Protection with Integrated Modbus RTU Communication
The ABB PR222DS/PD-LSI combines electronic circuit protection with digital communication in a single Tmax T4 release. The L function protects against sustained overloads, the S function provides delayed short-circuit protection for coordination with other protective devices, and the I function provides rapid response to severe short-circuit conditions.
Its integrated Modbus RTU dialogue capability allows a compatible Tmax T4 circuit breaker to participate in an RS-485 communication network. The PR222DS/PD platform supports communication of phase-current measurements, circuit-breaker and protection status, alarms and events, while compatible accessories can enable remote opening, closing and reset functions within a supervised power-distribution system.
Typical Applications
- ABB SACE Tmax T4 moulded case circuit breaker assemblies.
- Intelligent low-voltage distribution switchboards.
- Building management and power supervision systems.
- Industrial automation networks using Modbus RTU.
- Main and sub-distribution feeders requiring LSI protection.
- Remote electrical monitoring and circuit-breaker supervision.
- Manufacturing, process and infrastructure power-distribution systems.
