Why Choose the ABB PR222DS/PD-LSI In=250 MODBUS T4 3P?
The ABB PR222DS/PD-LSI In=250 MODBUS T4 3P, order code 1SDA054637R1, is a solid-state electronic protection release with communication capability designed for compatible ABB SACE Tmax T4 moulded case circuit breaker assemblies. Rated at 250 A, this three-pole release combines electronic circuit protection with Modbus communication for integration into monitored electrical distribution systems.
The PR222DS/PD-LSI provides LSI protection functions: long-time overload protection (L), short-time selective short-circuit protection (S) and instantaneous short-circuit protection (I). This combination enables coordinated protection of feeders and distribution circuits while providing greater flexibility than basic thermal-magnetic protection.
The 1SDA054637R1 is specifically configured for three-pole Tmax T4 applications with a rated current of 250 A. Its Modbus communication capability supports connection to compatible monitoring and automation systems. The unit is supplied as an electronic protection release rather than a complete MCCB and must be combined with a compatible ABB Tmax T4 breaking part and associated components.
Key Advantages
- Genuine ABB PR222DS/PD-LSI electronic protection release.
- 250 A rated current for compatible Tmax T4 circuit breaker assemblies.
- Three-pole (3P) configuration for three-phase distribution systems.
- LSI protection covering overload, selective short-circuit and instantaneous short-circuit conditions.
- Integrated Modbus communication capability for compatible monitoring and automation systems.
- Electronic protection supports improved selectivity and coordination within electrical distribution networks.
- Designed specifically for compatible ABB SACE Tmax T4 moulded case circuit breakers.
- Modular design enables pairing with the appropriate Tmax T4 breaking unit.

Communicating Electronic Protection for ABB SACE Tmax T4
The electronic release forms the protection and monitoring element of a compatible moulded case circuit breaker assembly. The PR222DS/PD-LSI monitors circuit current and provides long-time, short-time and instantaneous protection functions, while the associated Tmax T4 breaking unit performs the physical interruption of the electrical circuit when a trip command is initiated.
In addition to its LSI protection functions, the 1SDA054637R1 incorporates Modbus communication capability, allowing a compatible Tmax T4 installation to form part of a wider electrical monitoring or automation system. With a rated current of 250 A and a three-pole configuration, it is particularly suited to industrial feeders, switchboards and distribution systems requiring electronic protection together with communication functionality.
Typical Applications
- Compatible ABB SACE Tmax T4 moulded case circuit breaker assemblies.
- Industrial electrical distribution systems.
- Three-phase feeder protection.
- Electrical switchboards and distribution panels.
- Building and industrial energy management systems.
- Electrical systems requiring Modbus-based monitoring or automation.
- Industrial machinery and process installations.
- OEM electrical distribution and control assemblies.
