Why Choose the ABB T5V 400 PR221DS-I Circuit Breaker?
The ABB T5V 400 PR221DS-I, order code 1SDA054382R1, is a high-performance 3-pole moulded case circuit breaker (MCCB) designed for short-circuit protection and switching in demanding low-voltage electrical systems. Part of the proven ABB SACE Tmax T5 series, it combines a 400 A frame with a 320 A PR221DS-I electronic trip unit.
The PR221DS-I is an electronic instantaneous protection release designed to provide rapid operation under short-circuit conditions. This protection configuration is particularly useful where overload protection is provided separately or where the breaker is coordinated as part of a motor or specialised distribution protection system.
The T5V performance level provides an exceptional ultimate short-circuit breaking capacity of 200 kA at 415 V AC. This version features 3-pole fixed construction with front terminals, providing a robust solution for industrial switchboards, motor circuits, machinery and distribution systems with very high prospective fault currents.

High-Performance Electronic Short-Circuit Protection
The ABB PR221DS-I electronic release is designed around the instantaneous short-circuit protection function. It responds rapidly when current rises to a severe fault level, enabling the circuit breaker to interrupt the fault and limit the potential impact on cables, switchgear and connected equipment.
ABB identifies three-pole Tmax T5 circuit breakers equipped with PR221DS-I releases as suitable for motor protection applications when coordinated with the appropriate overload protection equipment. Combined with the T5V breaker’s very high short-circuit breaking performance, this makes the 1SDA054382R1 particularly suitable for demanding industrial electrical systems.
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 separate overload protection.
- Installations with very high prospective short-circuit currents.
