1SDA054102R1 ABB T4V 250 PR222DS/P-LSIG In=100A 3P Fixed Circuit Breaker

Why Choose the ABB 1SDA054102R1 T4V 250 Circuit Breaker?

The ABB 1SDA054102R1 is a SACE Tmax T4V 250 three-pole moulded case circuit breaker designed for demanding low-voltage power distribution applications. It combines the high-breaking-capacity T4V platform with a 100 A PR222DS/P-LSIG electronic trip unit, providing comprehensive electronic protection against overload, short-circuit and earth-fault conditions.

The PR222DS/P-LSIG solid-state release provides long-time, short-time, instantaneous and ground-fault protection functions. Adding the ground-fault function to the standard LSI protection suite enables the breaker to address a broader range of electrical fault conditions while supporting coordinated protection within suitably engineered industrial and commercial distribution systems.

The 1SDA054102R1 features a fixed three-pole construction with front terminals and a rated operational voltage of up to 690 V AC. The T4V performance level provides an ultimate short-circuit breaking capacity of 200 kA at 380–415 V AC, making this MCCB particularly suitable for installations with high prospective fault currents.

High-Breaking-Capacity LSIG Protection for Demanding Networks

The PR222DS/P-LSIG electronic trip unit provides four principal protection functions. Long-time protection addresses sustained overloads, short-time protection responds to higher fault currents while supporting selective coordination, instantaneous protection enables rapid interruption of severe short circuits, and ground-fault protection provides an additional protective function for earth-fault conditions.

Combined with the T4V platform's exceptional short-circuit performance, the 100 A PR222DS/P-LSIG release makes the ABB 1SDA054102R1 suitable for distribution systems requiring both sophisticated electronic protection and very high fault-interruption capability. Its 200 kA Icu at 380–415 V AC provides substantial protection capability in high-fault-level installations.
