Why Choose the ABB 1SDA054648R1 PR222DS/PD-LSIG Electronic Trip Unit?
The ABB 1SDA054648R1 is a PR222DS/PD-LSIG 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 comprehensive electronic circuit protection with Modbus communication for intelligent industrial and commercial low-voltage distribution systems.
The PR222DS/PD-LSIG provides LSIG protection functions, comprising long-time overload protection (L), short-time short-circuit protection (S), instantaneous short-circuit protection (I) and ground-fault protection (G). This combination supports protection against overloads, short circuits and earth-fault conditions while providing communication capability for integration into compatible power monitoring and automation architectures.
Designed specifically for the ABB SACE Tmax T4 320 platform, the 1SDA054648R1 has a rated current of 320 A and a three-pole configuration for AC applications. 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-LSIG electronic trip unit.
- 320 A rated current for compatible ABB Tmax T4 320 circuit breakers.
- Comprehensive LSIG electronic protection.
- Modbus communication for integration with compatible monitoring and automation systems.

LSIG Protection with Modbus Communication for ABB Tmax T4 320
The PR222DS/PD-LSIG combines four electronic protection functions within a communication-capable trip unit. Long-time protection responds to sustained overloads, short-time protection supports coordinated response to short-circuit currents, instantaneous protection enables rapid tripping during severe faults, and ground-fault protection provides an additional response to earth-fault conditions.
The Modbus communication capability makes the 1SDA054648R1 particularly suitable where circuit protection forms part of a wider power monitoring, supervision or automation system. As the 320 A three-pole electronic release rather than a complete MCCB, its final circuit-breaking characteristics depend on the compatible ABB Tmax T4 320 breaking part with which it 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.
- Applications requiring ground-fault protection.
- Building and industrial power monitoring systems.
- Electrical distribution systems requiring Modbus communication.
- OEM switchgear and automated control panel assemblies.
