1SDA062833R1 ABB T7V 1000 PR231/P-I 1000 A 3-Pole MCCB

Why Choose the ABB T7V 1000 PR231/P-I 1SDA062833R1 Circuit Breaker?

The ABB 1SDA062833R1 is a high-performance SACE Tmax T7V 1000 moulded case circuit breaker (MCCB) designed for short-circuit protection and switching in demanding low-voltage electrical systems. This configuration combines a 1000 A rated current, three-pole construction and the ABB PR231/P-I electronic trip unit for instantaneous 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 415 V AC, making it suitable for demanding industrial switchboards, motor circuits and high-capacity power distribution systems.

The 1SDA062833R1 is supplied as a three-pole fixed circuit breaker with front terminals. The PR231/P-I release provides instantaneous short-circuit protection without an integral long-time overload function, making this configuration particularly suitable where overload protection is provided separately and the MCCB is required to deliver high-capacity fault interruption.

Very High Breaking Capacity for 1000 A Circuits

The ABB SACE Tmax T7 platform is engineered for high-current low-voltage installations where dependable interruption of severe prospective fault currents is essential. The T7V 1000 combines a 1000 A current rating with ABB's V performance level, delivering an ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC and up to 200 kA at 220–230 V AC.

The PR231/P-I electronic trip unit provides instantaneous short-circuit protection for rapid interruption of high fault currents. This protection characteristic makes the breaker particularly suitable for motor and other high-current applications where overload protection is coordinated through separate equipment while the MCCB provides circuit isolation and high-capacity short-circuit protection.

Typical Applications

• High-current industrial electrical systems.
• Motor circuits with separate overload protection.
• Motor control centres and industrial switchboards.
• Manufacturing and process-industry installations.
• Low-voltage systems with high prospective fault currents.
• Industrial machinery and plant power systems.
• Fixed switchgear requiring very high short-circuit breaking capacity.
