1SDA062961R1 ABB T7V 1250 PR231/P-I 1250 A 3-Pole MCCB

Why Choose the ABB 1SDA062961R1 T7V 1250 Circuit Breaker?

The ABB 1SDA062961R1, extended product type T7V 1250 PR231/P I In=1250A 3p F F, is a high-performance moulded case circuit breaker (MCCB) designed for switching and short-circuit protection 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-I solid-state electronic trip unit for dependable protection against high fault currents.

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-I electronic release provides adjustable instantaneous short-circuit protection, allowing the protection threshold to be matched to 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 400 V AC, the T7V 1250 is engineered for installations with very high prospective fault currents. Its robust Tmax construction, 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 provide switching and protection for low-voltage electrical distribution systems exposed to substantial fault currents. By rapidly interrupting short-circuit currents, the breaker helps protect cables, switchgear and connected electrical equipment while supporting the safety and availability of the installation.

The PR231/P-I electronic trip unit provides adjustable instantaneous short-circuit protection, allowing the protection threshold to be configured between 1250–12500 A. Combined with the high breaking capacity of the T7V platform, the 1SDA062961R1 provides a robust solution for industrial power systems requiring dependable interruption of very high prospective fault currents.

Typical Applications

• Main and sub-main low-voltage distribution boards.
• Industrial switchboards and power distribution assemblies.
• Manufacturing and process plants.
• Commercial and infrastructure power distribution.
• High-current feeder and equipment protection.
• Industrial machinery and production systems.
• Electrical networks with very high prospective short-circuit currents.
