1SDA062846R1 ABB T7V 1000 PR332/P LSI 1000 A 4-Pole MCCB

Why Choose the ABB T7V 1000 PR332/P LSI 1SDA062846R1 Circuit Breaker?

The ABB 1SDA062846R1 is a high-performance SACE Tmax T7V 1000 moulded case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage power distribution systems. This configuration combines a 1000 A rated current, four-pole construction and the advanced ABB PR332/P LSI electronic trip unit for comprehensive overload and short-circuit protection.

As part of the ABB SACE Tmax T7 series, the T7V 1000 is engineered for installations with exceptionally high prospective fault currents. Its V performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC, with breaking capacities specified across low-voltage systems up to 690 V AC.

The 1SDA062846R1 is supplied as a four-pole fixed circuit breaker with front terminals and a lever operating mechanism. Its PR332/P LSI solid-state release provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection, with independently adjustable settings to support selective and coordinated protection of high-current distribution circuits.
