1SDA062807R1 ABB T7L 1000 PR332/P LSIG 3P 1000 A Circuit Breaker

Why Choose the ABB 1SDA062807R1 T7L 1000 Circuit Breaker?

The ABB 1SDA062807R1 is a high-performance three-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax T7 range, designed for demanding low-voltage power distribution applications. Identified as T7L 1000 PR332/P LSIG In=1000A 3P F F, it combines a 1000 A rated uninterrupted current with ABB's advanced PR332/P electronic trip unit.

The PR332/P electronic trip unit provides comprehensive LSIG protection, incorporating long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. The overload release can be adjusted from 400–1000 A, while short-time and instantaneous protection settings provide flexibility for coordinating the breaker with other protective devices throughout the distribution system.

The 1SDA062807R1 is supplied as a three-pole fixed circuit breaker with front terminals and a lever operating mechanism. Its T7L construction provides an ultimate short-circuit breaking capacity of 120 kA at 380–415 V AC, making it particularly suitable for main distribution boards, industrial switchboards and high-current feeder circuits with substantial prospective fault currents.

PR332/P LSIG Electronic Circuit Protection

The PR332/P electronic trip unit provides four complementary protection functions for demanding distribution systems. The L function protects against sustained overloads, the S function provides short-time protection for coordination during high-current faults, and the I function provides rapid interruption of severe short-circuit currents. The additional G function provides integrated ground-fault protection.

Combined with the high-breaking-capacity T7L 1000 platform, the adjustable PR332/P trip unit allows protection characteristics to be coordinated with the requirements of the protected circuit and other protective devices. With an Icu of 120 kA at 380–415 V AC, the ABB 1SDA062807R1 is particularly well suited to high-current distribution systems where substantial prospective fault levels must be safely interrupted.

Typical Applications

• Industrial low-voltage main distribution boards.
• High-current feeder and sub-main protection.
• Manufacturing and process plant switchboards.
• Commercial building main electrical distribution.
• Infrastructure and utility distribution assemblies.
• Installations requiring electronic ground-fault protection.
• Power distribution systems with high prospective short-circuit currents.
