1SDA062850R1 ABB T7V 1000 PR231/P-LS/I 1000 A 3-Pole MCCB

Why Choose the ABB 1SDA062850R1 T7V 1000 Circuit Breaker?

The ABB 1SDA062850R1, extended product type T7V 1000 PR231/P LS/I In=1000A 3p F F M, is a high-performance moulded case circuit breaker (MCCB) designed for protection and switching in high-current low-voltage electrical distribution systems. As part of the established ABB SACE Tmax T7 series, it combines a 1000 A rated current with a PR231/P-LS/I solid-state electronic trip unit for dependable overload and short-circuit protection.

This T7V configuration is a fixed three-pole circuit breaker with front terminals and a stored-energy operating mechanism, making it suitable for demanding industrial switchboards and power distribution assemblies. The PR231/P-LS/I release provides adjustable long-time overload and short-circuit protection, with protection settings that can be coordinated with the requirements of the electrical installation.

With a rated uninterrupted current of 1000 A and a rated ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC, the T7V 1000 is engineered for installations with very high prospective fault currents. Its robust Tmax construction, high breaking performance and fixed front-terminal arrangement make it well suited to industrial plants, infrastructure and large low-voltage power distribution systems.

High-Performance Protection for Power Distribution

Moulded case circuit breakers such as the ABB Tmax T7V protect low-voltage electrical distribution systems against excessive currents caused by overload and short-circuit conditions. By interrupting dangerous fault currents, the breaker helps protect cables, switchgear and connected equipment while supporting the safety and availability of the electrical installation.

The PR231/P-LS/I electronic trip unit provides adjustable protection characteristics that allow the breaker to be coordinated with the requirements of the distribution network. Combined with the high breaking capacity of the T7V platform, the 1SDA062850R1 provides a robust solution for industrial power systems where high fault-current performance and configurable protection are required.

Typical Applications

• Main and sub-main low-voltage distribution boards.
• Industrial switchboards and electrical control panels.
• Manufacturing and process plants.
• Commercial and infrastructure power distribution.
• Transformer secondary and feeder protection.
• High-current machinery and production systems.
