Why Choose the ABB PR221DS-LS/I 630A T6 4-Pole Electronic Trip Unit?
The ABB PR221DS-LS/I In=630 T6 630 4P, order code 1SDA060357R1, 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 system, it provides long-time, short-time and instantaneous overcurrent protection for high-current low-voltage electrical distribution applications.
Rated at 630 A, the PR221DS-LS/I continuously monitors current through the associated circuit breaker and initiates tripping when configured protection thresholds are exceeded. Its LS/I functionality combines overload protection with selective short-circuit and instantaneous fault protection, providing a flexible electronic alternative to conventional thermomagnetic releases.
This version is specifically intended for 4-pole Tmax T6 circuit breaker configurations. The combination of a 630 A rating, electronic protection technology and multiple overcurrent protection functions makes the 1SDA060357R1 suitable for industrial switchboards, feeder protection and other demanding three-phase plus neutral power distribution systems.

Electronic Overcurrent Protection for Tmax T6 Circuit Breakers
Electronic trip units monitor the current flowing through a circuit breaker and compare it with configured protection thresholds. The PR221DS-LS/I provides complementary long-time, short-time and instantaneous functions, allowing the associated Tmax T6 breaker to respond appropriately to sustained overloads, short-duration high currents and severe short-circuit faults.
The 630 A rating and four-pole configuration make this trip unit suitable for high-current three-phase plus neutral distribution systems. When installed in a compatible Tmax T6 assembly, it provides reliable electronic protection for feeders, switchboards and industrial power distribution equipment.
Typical Applications
- ABB Tmax T6 moulded case circuit breaker assemblies.
- Industrial low-voltage distribution boards.
- Three-phase plus neutral power distribution systems.
- Main and feeder circuit protection.
- Manufacturing and process plant switchgear.
- Machinery and industrial power distribution panels.
