Why Choose the ABB T5L 400 PR222DS/P-LSIG Circuit Breaker?
The ABB T5L 400 PR222DS/P-LSIG, order code 1SDA054370R1, is a high-performance 3-pole moulded case circuit breaker (MCCB) for protection and switching in demanding low-voltage electrical distribution systems. Part of the proven ABB SACE Tmax T5 series, it combines a 400 A frame with a 320 A PR222DS/P-LSIG electronic trip unit.
The PR222DS/P-LSIG electronic release provides comprehensive long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. Its adjustable protection functions enable the breaker to be coordinated with downstream circuits and equipment while providing selective and dependable protection across industrial and commercial power distribution networks.
The T5L 400 offers an ultimate short-circuit breaking capacity of 120 kA at 380–415 V AC. This version is a 3-pole fixed circuit breaker with front terminals, making it well suited to switchboards, distribution panels, industrial plants and infrastructure installations requiring advanced electronic protection.

Advanced LSIG Electronic Circuit Protection
The ABB PR222DS/P-LSIG electronic trip unit provides multiple protection functions within a single circuit breaker. Long-time protection responds to sustained overloads, short-time and instantaneous functions protect against short-circuit conditions, and the integrated earth-fault function provides additional protection against ground-fault currents.
Adjustable electronic protection enables improved coordination between upstream and downstream protective devices compared with basic fixed protection. This makes the T5L 400 particularly suitable for distribution systems where selectivity, equipment protection and continuity of supply are important design considerations.
Typical Applications
- Industrial low-voltage distribution boards.
- Main and feeder circuit protection.
- Manufacturing and process plants.
- Commercial building electrical distribution.
- Infrastructure and utility installations.
- Machinery and automation power distribution.
- Systems requiring adjustable LSIG electronic protection.
