Why Choose the ABB T7L 800 1SDA062693R1 Circuit Breaker?
The ABB 1SDA062693R1 is a high-performance Tmax T7L 800 moulded-case circuit breaker designed for demanding low-voltage power distribution applications. Rated at 800 A, this three-pole breaker combines a fixed mounting arrangement, front terminals and an advanced PR332/P LI electronic trip unit for dependable overload and instantaneous short-circuit protection.
As part of the ABB SACE Tmax T7 range, the T7L 800 is engineered for installations with high prospective fault currents. Its L short-circuit performance level provides a rated ultimate short-circuit breaking capacity of 120 kA at 415 V AC, with similarly high fault-clearing capability across a wide operating-voltage range.
The PR332/P LI trip unit provides long-time overload protection and instantaneous short-circuit protection, while the breaker's 800 A rated current, three-pole configuration and fixed front-terminal construction make it particularly suitable for main switchboards, industrial distribution systems and other high-current electrical installations.

High-Performance Protection for Low-Voltage Power Distribution
Moulded-case circuit breakers protect electrical distribution circuits by interrupting overload and short-circuit currents while also providing switching and isolation capability. The ABB T7L 800 combines a high-current frame with an electronic trip system, providing repeatable protection performance for demanding industrial and commercial installations.
The PR332/P LI trip unit provides long-time overload and instantaneous short-circuit protection, while the T7L breaker's high fault-clearing capability enables it to be applied in systems where prospective short-circuit currents are substantial. Its 120 kA Icu at 415 V AC makes the 1SDA062693R1 particularly suitable for high-capacity distribution networks and major switchboard incomers or feeders.
Typical Applications
- Industrial low-voltage switchboards.
- Main and sub-main power distribution systems.
- Manufacturing and process-industry electrical installations.
- Commercial and infrastructure distribution systems.
- High-fault-level electrical networks.
- OEM switchgear and power distribution assemblies.
