Why Choose the ABB PR221DS-I 630A T6 4-Pole Electronic Trip Unit?
The ABB PR221DS-I In=630 T6 630 4P, order code 1SDA060358R1, is a solid-state electronic trip unit designed for compatible ABB SACE Tmax T6 moulded case circuit breakers. Part of the established ABB Tmax T6 protection platform, this release provides instantaneous short-circuit protection for high-current low-voltage electrical distribution systems.
Rated at 630 A, the PR221DS-I monitors current through the associated circuit breaker and initiates tripping when the instantaneous protection threshold is exceeded. The I-only protection characteristic is intended for applications where rapid short-circuit protection is required and overload protection is provided separately or is not required from the circuit breaker trip unit.
This version is specifically configured for 4-pole Tmax T6 circuit breaker assemblies. Its electronic protection technology, 630 A current rating and four-pole construction make the 1SDA060358R1 suitable for compatible three-phase plus neutral distribution systems requiring dependable instantaneous fault protection.

Reliable Instantaneous Protection for Tmax T6 Circuit Breakers
Electronic instantaneous trip units are designed to detect severe overcurrent conditions and command the associated circuit breaker to open rapidly when the configured fault threshold is exceeded. This helps limit the thermal and mechanical stresses that high short-circuit currents can impose on conductors, switchgear and connected electrical equipment.
The ABB PR221DS-I combines a 630 A current rating with an instantaneous protection characteristic in a four-pole configuration. When installed in a compatible Tmax T6 assembly, it provides focused electronic short-circuit protection for industrial feeders, distribution circuits and other high-current electrical systems.
Typical Applications
- ABB Tmax T6 moulded case circuit breaker assemblies.
- Industrial low-voltage distribution boards.
- Three-phase plus neutral electrical systems.
- High-current feeder circuits.
- Manufacturing and process plant switchgear.
- Machinery and industrial power distribution panels.
