Why Choose the ABB T7L 800 1SDA062678R1 Circuit Breaker?
The ABB 1SDA062678R1 is a high-performance SACE Tmax T7L moulded case circuit breaker (MCCB) designed for protection and control of demanding low-voltage power distribution circuits. Identified by ABB as T7L 800 PR332/P LSI In=800A 3p F F, it combines an 800 A rated current with the advanced PR332/P electronic trip unit for comprehensive overload and short-circuit protection.
The T7L version provides a high ultimate short-circuit breaking capacity of 120 kA at 415 V AC, making it suitable for industrial and commercial distribution systems where substantial prospective fault currents may occur. Its PR332/P LSI electronic trip unit provides long-time overload (L), short-time short-circuit (S) and instantaneous short-circuit (I) protection functions, enabling effective protection and selectivity within complex electrical distribution networks.
With an adjustable current range of 320–800 A, this three-pole circuit breaker can be configured to suit the requirements of the protected circuit. The fixed (F) installation and front terminal (F) configuration make the 1SDA062678R1 particularly suitable for integration into industrial switchboards, distribution panels and OEM power distribution assemblies.

Advanced Protection for Industrial Power Distribution
Moulded case circuit breakers such as the ABB SACE Tmax T7L protect electrical distribution systems against potentially damaging overload and short-circuit currents. The 1SDA062678R1 combines an 800 A rating with an ultimate breaking capacity of 120 kA at 415 V AC, providing robust protection for installations with high prospective fault levels.
The integrated PR332/P LSI electronic trip unit provides a more comprehensive protection arrangement than an LI-only release by adding short-time protection. Its long-time, short-time and instantaneous functions enable protection settings to be coordinated with downstream and upstream devices, supporting selective operation and improved continuity within industrial power distribution networks.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-main electrical switchboards.
- Manufacturing and process plant distribution systems.
- Commercial and infrastructure power distribution.
- High-current feeder and cable protection.
- OEM switchgear and electrical panel assemblies.
