1SDA054114R1 ABB T4V 250 PR222DS/P-LSIG In=100A 4P Fixed Circuit Breaker

Why Choose the ABB 1SDA054114R1 T4V 250 Circuit Breaker?

The ABB 1SDA054114R1 is a SACE Tmax T4V 250 four-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 electronic protection against overload, short-circuit and ground-fault conditions.

The PR222DS/P-LSIG electronic release provides long-time, short-time, instantaneous and ground-fault protection functions. This LSIG protection package extends conventional overcurrent protection with dedicated ground-fault functionality, supporting comprehensive protection and coordination within suitably engineered industrial, commercial and infrastructure distribution systems.

The 1SDA054114R1 features a fixed four-pole construction with front terminals and a rated operational voltage of up to 690 V AC. Its T4V performance level delivers an ultimate short-circuit breaking capacity of 200 kA at 380–415 V AC, providing substantial fault-interruption capability for installations with high prospective short-circuit currents.

Four-Pole LSIG Protection for High-Fault-Level Networks

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

Combined with the T4V platform's 200 kA ultimate breaking capacity at 380–415 V AC, the 100 A electronic release makes the ABB 1SDA054114R1 suitable for demanding distribution systems requiring sophisticated protection and very high fault-interruption capability. Its four-pole construction further supports applications where switching and protection across four conductors are required.
