Why Choose the ABB 1SDA062987R1 T7V 1250 Circuit Breaker?
The ABB 1SDA062987R1, extended product type T7V 1250 PR232/P LSI In=1250A 4p F F M, is a high-performance moulded case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage electrical distribution systems. Part of the ABB SACE Tmax T7 series, it combines a 1250 A rated uninterrupted current, four-pole construction and a PR232/P-LSI solid-state electronic trip unit.
The PR232/P-LSI release provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. Adjustable protection thresholds allow the breaker characteristics to be coordinated with the electrical installation, making it suitable for high-current feeders, incomers and distribution circuits where selective protection and reliable fault interruption are required.
With a rated ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC, the T7V 1250 is engineered for installations with very high prospective fault currents. This version is a fixed four-pole breaker with front terminals and a stored-energy operating mechanism, providing a robust solution for industrial switchboards, infrastructure and high-capacity power distribution assemblies.

Advanced Protection for High-Current 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. The four-pole construction makes the 1SDA062987R1 suitable for three-phase four-wire distribution systems where all four poles need to be incorporated into the circuit breaker arrangement.
The PR232/P-LSI electronic trip unit combines adjustable long-time overload, short-time delayed and instantaneous short-circuit protection. Together with the 150 kA breaking capacity at 380–415 V AC of the T7V platform and its stored-energy operating mechanism, the 1SDA062987R1 provides dependable protection and switching for high-current distribution networks with substantial prospective fault levels.
Typical Applications
- Main and sub-main low-voltage distribution boards.
- Three-phase four-wire electrical distribution systems.
- Industrial switchboards and power distribution assemblies.
- Main incomers and high-current feeder circuits.
- Manufacturing and process plants.
- Commercial and infrastructure power distribution.
- Transformer secondary and feeder protection.
- Electrical networks requiring coordinated short-time and instantaneous protection.
- Installations with very high prospective short-circuit currents.
