Why Choose the ABB PR221DS-I In=100 T4 4P?
The ABB PR221DS-I In=100 T4 4P, order code 1SDA054618R1, is an electronic protection release for ABB SACE Tmax T4 four-pole moulded case circuit breakers. With a rated current of 100 A, it is designed to provide instantaneous short-circuit protection as part of a compatible Tmax T4 circuit breaker assembly.
The PR221DS-I is the instantaneous-protection version of the ABB PR221DS electronic trip-release family. Its I protection function detects high short-circuit currents and initiates rapid tripping without an intentional time delay, enabling the associated Tmax T4 breaking unit to interrupt severe fault conditions.
Designed specifically for the Tmax T4 four-pole platform, the 1SDA054618R1 supports ABB's modular approach to moulded case circuit breaker configuration. It is a protection release rather than a standalone switching device and is intended to be combined with a compatible T4 breaking part to create the required MCCB assembly.

Electronic Instantaneous Protection for ABB Tmax T4 Circuit Breakers
The ABB PR221DS-I monitors current within a compatible Tmax T4 circuit breaker assembly and provides an instantaneous trip function when a severe short-circuit condition reaches the applicable protection threshold. The I function operates without an intentional short-circuit time delay, supporting rapid interruption of high fault currents by the associated breaking unit.
The 1SDA054618R1 is intended for a 100 A four-pole Tmax T4 configuration. When combined with a compatible ABB Tmax T4 breaking part, the release provides the electronic instantaneous protection function while the selected breaking unit supplies the required switching and short-circuit interruption capability.
Typical Applications
