Why Choose the ABB 1SDA054713R1 PR222DS/PD-LSIG 320 A Modbus T5 3P Electronic Trip Unit?
The ABB 1SDA054713R1 is a PR222DS/PD-LSIG solid-state electronic trip unit designed for three-pole ABB SACE Tmax T5 moulded-case circuit breakers. Rated at 320 A, it combines comprehensive electronic circuit protection with Modbus communication for low-voltage power distribution, monitoring and industrial automation applications.
The PR222DS/PD-LSIG provides long-time overload (L), selective short-circuit (S), instantaneous short-circuit (I) and ground-fault (G) protection. This combination enables the associated Tmax T5 circuit breaker to respond to sustained overloads, different levels of short-circuit current and earth-fault conditions while supporting coordinated protection throughout the electrical distribution system.
Designed for a three-pole (3P) Tmax T5 configuration, the release has a rated current of 320 A and an adjustable instantaneous short-circuit release range of 480–3840 A. Its Modbus capability makes it particularly suitable for installations combining circuit protection with remote supervision, automation and centralised power-management systems.

Advanced LSIG Protection with Modbus Communication
The ABB PR222DS/PD-LSIG continuously evaluates circuit current and provides multiple levels of electronic protection. Long-time protection responds to sustained overload conditions, short-time and instantaneous functions protect against short circuits, and the ground-fault function adds protection against earth-fault currents within the capabilities of the associated system.
Communication capability extends the release beyond conventional standalone protection by enabling integration with compatible supervision and automation systems. Combined with an ABB SACE Tmax T5 circuit breaker, the 1SDA054713R1 provides a capable solution for installations requiring 320 A LSIG protection, adjustable fault response and networked electrical monitoring.
