1SDA062864R1 ABB T7V 1000 PR332/P LSIRc 1000 A 4-Pole MCCB

Why Choose the ABB T7V 1000 PR332/P LSIRc 1SDA062864R1 Circuit Breaker?

The ABB 1SDA062864R1 is a high-performance SACE Tmax T7V 1000 moulded case circuit breaker (MCCB) designed for demanding low-voltage power distribution systems. It combines a 1000 A rated current, four-pole construction and the advanced ABB PR332/P LSIRc electronic trip unit for adjustable overload, short-circuit and residual-current protection.

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

The 1SDA062864R1 is a four-pole fixed circuit breaker with front terminals and a stored-energy operating mechanism. Its PR332/P LSIRc solid-state release provides long-time overload, short-time delayed and instantaneous short-circuit protection together with residual-current protection, providing a comprehensive protection solution for high-current distribution installations.

Advanced LSIRc Protection for High-Current Distribution

The ABB SACE Tmax T7 platform is designed for high-current low-voltage installations where both substantial fault-interruption capability and configurable electronic protection are required. The T7V 1000 combines a 1000 A current rating with ABB's V performance level, delivering an ultimate breaking capacity of 150 kA at 380–415 V AC and up to 200 kA at 220–230 V AC.

The PR332/P LSIRc electronic trip unit combines long-time overload, short-time delayed and instantaneous short-circuit functions with residual-current protection. This enables the breaker to provide coordinated distribution protection while also detecting residual leakage currents, making it particularly useful where enhanced protection against current flowing outside the intended circuit path is required.

Typical Applications

• Industrial low-voltage power distribution systems.
• Four-pole main and feeder protection.
• High-current electrical switchboards.
• Manufacturing and process-industry electrical systems.
• Commercial and infrastructure distribution assemblies.
• Installations requiring integrated residual-current protection.
• Fixed switchgear requiring high short-circuit breaking capacity and electronic protection.
