Why Choose the ABB T5L 630 PR222DS/P-LSIG Circuit Breaker?
The ABB T5L 630 PR222DS/P-LSIG, order code 1SDA054427R1, is a high-performance 4-pole moulded case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage power distribution systems. Part of the ABB SACE Tmax T5 series, it combines a 630 A rated current with an advanced PR222DS/P-LSIG solid-state electronic trip unit.
The PR222DS/P-LSIG electronic release provides long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection. Its adjustable protection settings allow effective coordination with conductors, loads and other protective devices throughout industrial and commercial distribution networks.
The T5L performance level provides an ultimate short-circuit breaking capacity of 120 kA at 380–415 V AC. With its 4-pole fixed construction and front terminals, the 1SDA054427R1 is well suited to three-phase plus neutral switchboards, main and feeder circuits and installations requiring comprehensive LSIG electronic protection.

Advanced LSIG Electronic Circuit Protection
The ABB PR222DS/P-LSIG electronic trip unit combines four principal protection functions. Long-time protection responds to sustained overloads, short-time protection provides a configurable delayed response to short circuits, instantaneous protection rapidly disconnects severe faults, and the integrated earth-fault function adds protection against current flowing to earth.
The adjustable LSIG functions allow the T5L 630 to be coordinated with the wider electrical protection system. In this four-pole configuration, configurable neutral protection further supports three-phase plus neutral networks, making the breaker a flexible solution for high-current industrial and commercial distribution.
Typical Applications
- Industrial low-voltage distribution switchboards.
- Main incoming and feeder circuit protection.
- Three-phase plus neutral distribution systems.
- Manufacturing and process plants.
- Commercial building electrical distribution.
- Infrastructure and utility installations.
- Systems requiring adjustable LSIG electronic protection.
