Why Choose the ABB PR222DS/PD-LSIG In=320 Modbus T5 4-Pole Electronic Trip Unit?
The ABB 1SDA054717R1 is a PR222DS/PD-LSIG electronic trip unit rated at 320 A, designed for compatible four-pole ABB SACE Tmax T5 moulded-case circuit breakers. Part of the ABB Tmax T4–T8 product family, it combines comprehensive electronic circuit protection with Modbus communication for intelligent low-voltage power distribution.
The PR222DS/PD platform provides LSIG protection functions, combining long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. These functions provide broad protection against common electrical fault conditions while allowing the circuit breaker to form part of a coordinated protection system.
With a rated current of 320 A, a four-pole configuration and Modbus communication, the PR222DS/PD-LSIG is particularly suited to intelligent switchboards and three-phase plus neutral distribution systems where protection, earth-fault detection and communication with supervisory systems are required.
Key Advantages
- Comprehensive LSIG electronic protection for compatible ABB SACE Tmax T5 circuit breakers.

Comprehensive Protection with Modbus Connectivity
LSIG electronic protection covers a wide range of electrical fault conditions. Long-time protection responds to sustained overloads, short-time and instantaneous functions address short-circuit currents, and the earth-fault function provides additional protection against current flowing through unintended paths to earth.
The PR222DS/PD platform also adds communication capability to the protection system. Modbus connectivity enables integration with compatible supervisory, monitoring and automation equipment, making the 1SDA054717R1 well suited to connected switchboards and industrial power management systems.
