1SDA063070R1 ABB T7L 1600 PR332/P-LSI 1600 A 4-Pole MCCB

Why Choose the ABB 1SDA063070R1 T7L 1600 Circuit Breaker?

The ABB 1SDA063070R1, extended product type T7L 1600 PR332/P LSI 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-LSI electronic trip unit.

The PR332/P-LSI electronic release provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. This combination enables protection characteristics to be coordinated with downstream circuits while providing rapid interruption of severe faults, making the breaker suitable for high-current incomers, feeders and distribution circuits.

The T7L 1600 provides a rated ultimate short-circuit breaking capacity of 120 kA at 380–415 V AC and operates at voltages up to 690 V AC. This version is supplied as a fixed four-pole breaker with front terminals, providing a robust solution for industrial switchboards, infrastructure and high-capacity power distribution assemblies.

Selective 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 1SDA063070R1 suitable for three-phase four-wire distribution systems where four-pole switching is required.

The PR332/P-LSI electronic trip unit combines long-time overload protection with short-time delayed and instantaneous short-circuit protection. Together with the 120 kA breaking capacity at 380–415 V AC and 20 kA for 1 s short-time withstand capability, the breaker is well suited to high-current networks where protection coordination and dependable fault interruption are important.
