Why Choose the ABB T5L 400 PR222DS/P-LSIG Circuit Breaker?
The ABB T5L 400 PR222DS/P-LSIG, order code 1SDA054371R1, is a high-performance 3-pole moulded case circuit breaker (MCCB) designed 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 and rated current with an advanced PR222DS/P-LSIG 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. Adjustable protection thresholds allow the breaker to be coordinated with connected circuits and downstream protective devices, supporting selective and dependable electrical distribution.
The T5L performance level provides an ultimate short-circuit breaking capacity of 120 kA at 400 V AC. This version is a 3-pole fixed circuit breaker with front terminals, making it suitable for industrial switchboards, distribution panels, infrastructure and other installations requiring advanced electronic protection.

Advanced LSIG Electronic Circuit Protection
The ABB PR222DS/P-LSIG electronic trip unit combines four important protection functions within the circuit breaker. Long-time protection responds to sustained overloads, short-time protection provides a configurable delayed response to short circuits, instantaneous protection rapidly clears severe faults, and the integrated earth-fault function detects ground-fault conditions.
The adjustable electronic protection ranges allow engineers to coordinate the T5L 400 with upstream and downstream protective devices. This flexibility makes the breaker particularly suitable for installations where selectivity, equipment protection and continuity of electrical supply are important design considerations.

- Industrial low-voltage distribution boards.
- Main incoming 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.
