1SDA062822R1 ABB T7L 1000 PR332/P-LSI 1000 A 3-Pole MCCB

Why Choose the ABB 1SDA062822R1 T7L 1000 Circuit Breaker?

The ABB 1SDA062822R1, extended product type T7L 1000 PR332/P LSI In=1000A 3p F F M, is a high-performance moulded case circuit breaker (MCCB) designed for protection and switching of high-current low-voltage electrical distribution systems. As part of the established ABB SACE Tmax T7 series, it combines a 1000 A rated current with an advanced PR332/P-LSI electronic trip unit for comprehensive overload and short-circuit protection.

This T7L configuration uses a fixed three-pole breaker body with front terminals and a stored-energy operating mechanism, making it suitable for demanding industrial switchboards and power distribution assemblies. The PR332/P-LSI electronic release provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection, allowing protection characteristics to be coordinated with the requirements of the electrical installation.

With a rated uninterrupted current of 1000 A and a rated ultimate short-circuit breaking capacity of 120 kA at 380–415 V AC, the T7L 1000 is engineered for installations where high fault-current performance is required. Its robust fixed construction, electronic protection and front-terminal arrangement make it well suited to industrial plants, infrastructure and large low-voltage power distribution systems.

Reliable Circuit Protection for High-Power Distribution

Moulded case circuit breakers such as the ABB Tmax T7L protect electrical distribution systems against excessive current caused by overloads and short circuits. By interrupting dangerous fault currents rapidly, the breaker helps protect cables, switchgear and connected equipment while supporting the safety and availability of the electrical installation.

The PR332/P-LSI electronic trip unit provides adjustable long-time, short-time and instantaneous protection, enabling the breaker characteristics to be coordinated with downstream and upstream protection devices. Combined with the high breaking capacity of the T7L platform, this makes the 1SDA062822R1 particularly suitable for complex industrial distribution networks where selective and configurable circuit protection is required.

Typical Applications

• Main and sub-main low-voltage distribution boards.
• Industrial switchboards and electrical control panels.
• Manufacturing and process plants.
• Commercial and infrastructure power distribution.
• Transformer secondary and feeder protection.
• High-current machinery and production systems.
• Power distribution systems with high prospective short-circuit currents.
