1SDA062962R1 ABB T7V 1250 PR231/P-LS/I 1250 A 3-Pole MCCB

Why Choose the ABB 1SDA062962R1 T7V 1250 Circuit Breaker?

The ABB 1SDA062962R1, extended product type T7V 1250 PR231/P LS/I In=1250A 3p F F, 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 1250 A rated uninterrupted current with a PR231/P-LS/I electronic trip unit for adjustable overload and short-circuit protection.

This T7V configuration is a fixed three-pole circuit breaker with front terminals and a lever operating mechanism, making it suitable for demanding industrial switchboards and power distribution assemblies. The PR231/P-LS/I electronic release provides long-time overload protection together with selectable short-time delayed or instantaneous short-circuit protection, allowing the protection characteristics to be coordinated with the requirements of the electrical installation.

With a rated uninterrupted current of 1250 A and 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. Its robust Tmax construction, configurable electronic protection 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 rapidly interrupting dangerous fault currents, the breaker helps protect cables, switchgear and connected equipment while supporting the safety and continuity of the electrical installation.

The PR231/P-LS/I electronic trip unit provides adjustable long-time overload protection together with selectable short-time delayed or instantaneous short-circuit protection. Combined with the high breaking capacity of the T7V platform, the 1SDA062962R1 provides a robust solution for industrial power systems requiring configurable protection, selective coordination and dependable interruption of very high prospective fault currents.

Typical Applications

• Main and sub-main low-voltage distribution boards.
• 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 with very high prospective short-circuit currents.
