Why Choose the ABB 1SDA054647R1 PR222DS/PD-LSI Electronic Trip Unit?
The ABB 1SDA054647R1 is a PR222DS/PD-LSI electronic trip unit designed for compatible ABB SACE Tmax T4 320 moulded case circuit breakers. Rated at 320 A, this three-pole solid-state release combines electronic circuit protection with Modbus communication for intelligent industrial and commercial low-voltage distribution systems.
The PR222DS/PD-LSI provides LSI protection functions, comprising long-time overload protection (L), short-time short-circuit protection (S) and instantaneous short-circuit protection (I). These electronic functions support accurate protection and coordination while the integrated communication capability enables the trip unit to form part of compatible power monitoring and automation architectures.
Designed specifically for the ABB SACE Tmax T4 320 platform, the 1SDA054647R1 has a rated current of 320 A and a three-pole configuration. It is supplied as an electronic protection release for integration with compatible Tmax T4 320 breaker hardware and is therefore a circuit breaker component rather than a complete standalone MCCB.
Key Advantages
- Genuine ABB PR222DS/PD-LSI electronic trip unit.
- 320 A rated current for compatible ABB Tmax T4 320 circuit breakers.
- LSI electronic protection for overload and short-circuit conditions.
- Modbus communication for integration with compatible monitoring and automation systems.
- Long-time protection helps protect circuits against sustained overloads.
- Short-time protection supports coordinated response to short-circuit conditions.
- Instantaneous protection provides rapid response to severe short-circuit faults.
- Three-pole configuration for compatible three-phase Tmax T4 320 assemblies.

LSI Protection with Modbus Communication for ABB Tmax T4 320
The PR222DS/PD-LSI combines electronic circuit protection with communication functionality for intelligent low-voltage distribution applications. Long-time protection responds to sustained overload conditions, short-time protection provides a controlled response to short-circuit currents, and instantaneous protection enables rapid tripping when severe short-circuit conditions occur.
The Modbus communication capability makes the 1SDA054647R1 particularly suitable where compatible circuit breakers form part of a wider power monitoring, supervision or automation system. As the 320 A three-pole electronic release rather than a complete MCCB, the final circuit breaker's short-circuit breaking performance depends on the compatible ABB Tmax T4 320 breaking part with which the release is assembled.
Typical Applications
- ABB Tmax T4 320 moulded case circuit breaker assemblies.
- Intelligent low-voltage electrical distribution systems.
- Industrial electrical switchboards.
- Three-phase feeder protection.
- Building and industrial power monitoring systems.
- Manufacturing and process facilities.
- Electrical distribution systems requiring Modbus communication.
- OEM switchgear and automated control panel assemblies.
