1SDA063069R1 ABB T7L 1600 PR332/P-LI 1600 A 4-Pole MCCB

Why Choose the ABB 1SDA063069R1 T7L 1600 Circuit Breaker?

The ABB 1SDA063069R1, extended product type T7L 1600 PR332/P LI In=1600A 4p F F, 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 1600 A rated uninterrupted current, four-pole construction and a PR332/P-LI solid-state electronic trip unit.

The PR332/P-LI release provides long-time overload and instantaneous short-circuit protection for high-current power distribution circuits. Its adjustable protection thresholds allow the breaker characteristics to be matched to the requirements of the installation, with overload protection adjustable from 640–1600 A and instantaneous short-circuit protection adjustable from 2400–24000 A.

With a rated ultimate short-circuit breaking capacity of 120 kA at 380–415 V AC, the T7L 1600 is designed for installations with high prospective fault currents. This version is supplied as a fixed four-pole circuit breaker with front terminals and a lever operating mechanism, making it a robust solution for industrial switchboards, infrastructure and high-capacity power distribution assemblies.

Reliable Protection for High-Current Power Distribution

Moulded case circuit breakers such as the ABB Tmax T7L protect low-voltage electrical distribution systems against excessive currents caused by overload and short-circuit conditions. The four-pole construction makes the 1SDA063069R1 suitable for three-phase four-wire distribution systems where all four poles need to be incorporated into the circuit breaker arrangement.

The PR332/P-LI electronic trip unit combines adjustable long-time overload protection with instantaneous short-circuit protection. Together with the 120 kA breaking capacity at 380–415 V AC of the T7L platform, the 1SDA063069R1 provides dependable protection for high-current distribution networks requiring robust fault interruption and configurable electronic protection.

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.
