Why Choose the ABB T5V 400 PR221DS-I Circuit Breaker?
The ABB T5V 400 PR221DS-I, order code 1SDA054383R1, is a high-performance 3-pole moulded case circuit breaker (MCCB) designed for switching and short-circuit protection in demanding low-voltage electrical systems. Part of the proven ABB SACE Tmax T5 series, it combines a 400 A frame and rated current with a PR221DS-I solid-state electronic trip unit.
The PR221DS-I electronic release provides instantaneous short-circuit protection, enabling rapid interruption when current rises to a severe fault level. ABB identifies three-pole T5 breakers equipped with the PR221DS-I release as suitable for motor protection when correctly coordinated with the required overload protection equipment.
The T5V performance level provides an exceptional ultimate short-circuit breaking capacity of 200 kA at 380–415 V AC. This version is a 3-pole fixed circuit breaker with front terminals, making it suitable for industrial switchboards, motor circuits, machinery and power distribution systems with very high prospective fault currents.

High-Performance Electronic Short-Circuit Protection
The ABB PR221DS-I electronic release provides instantaneous protection against severe short-circuit currents. When the configured protection threshold is exceeded, the release commands rapid opening of the circuit breaker to isolate the fault and help protect cables, switchgear and connected electrical equipment.
The combination of the PR221DS-I release and the T5V breaker platform is particularly valuable where very high fault-current interruption capability is required. In motor applications, the instantaneous protection can be coordinated with suitable separate overload protection to provide an effective motor circuit protection system.
Typical Applications
- Industrial motor circuit protection.
- Motor control centres (MCCs).
- Industrial low-voltage switchboards.
- Machinery and automation power circuits.
- Manufacturing and process equipment.
- Three-phase circuits with coordinated overload protection.
- Installations with very high prospective short-circuit currents.
