Why Choose the ABB 1SDA062674R1 T7L 800 Circuit Breaker?
The ABB 1SDA062674R1 is a high-performance three-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax T7 range, engineered for demanding low-voltage power distribution applications. Identified as T7L 800 FF 3P PR231/P LS/I, it combines an 800 A rated current with a high 120 kA breaking capacity at 415 V AC.
At the heart of the breaker is ABB's PR231/P electronic trip unit with LS/I protection functions. This provides long-time overload protection together with short-circuit protection, enabling the breaker to protect cables, busbars and connected distribution equipment against damaging overcurrent conditions.
The 1SDA062674R1 is supplied as a three-pole fixed circuit breaker with front terminals. Its T7L high-breaking-capacity construction makes it particularly suitable for industrial switchboards, main distribution boards and feeder circuits where prospective short-circuit currents demand robust interruption performance.

PR231/P Electronic Protection with LS/I Functions
The PR231/P electronic trip unit monitors current flowing through the circuit breaker and initiates tripping when electrical conditions exceed the configured protection thresholds. The L function provides long-time protection against sustained overloads, while the short-circuit protection functions provide rapid intervention when significantly higher fault currents occur.
Combined with the T7L breaking capacity of 120 kA at 415 V AC, this protection package makes the ABB 1SDA062674R1 suitable for installations with substantial prospective fault levels. The fixed, front-terminal construction also supports practical integration into low-voltage switchboards and distribution assemblies.
Typical Applications
- Industrial low-voltage main distribution boards.
- High-current feeder and sub-main protection.
- Manufacturing and process plant switchboards.
- Commercial building power distribution systems.
- Infrastructure and utility distribution assemblies.
- Installations with high prospective short-circuit currents.
