Why Choose the ABB T7L 800 PR231/P-I 1SDA062689R1 Circuit Breaker?
The ABB 1SDA062689R1 is a high-performance Tmax T7L 800 moulded case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage electrical distribution systems. Configured as a three-pole fixed circuit breaker, it combines an 800 A rated current with the ABB PR231/P-I electronic trip unit for dependable short-circuit protection.
As part of the ABB Tmax T7 series, the T7L 800 provides high breaking capacity for industrial switchboards, distribution assemblies and power installations. The L performance level provides a rated ultimate short-circuit breaking capacity of up to 120 kA at 400 V AC, while the breaker is suitable for systems with rated operational voltages up to 690 V AC.
This configuration features three poles, fixed mounting, front terminals and a stored-energy operating mechanism. Its 800 A PR231/P-I electronic release provides instantaneous overcurrent protection, while the motorisable operating mechanism allows a compatible motor operator to be added where electrically operated switching is required.

High-Capacity Protection for Low-Voltage Distribution
The ABB Tmax T7 platform is engineered for high-current low-voltage distribution systems where compact construction and substantial short-circuit performance are required. The T7L performance level of this breaker provides up to 120 kA Icu at 400 V AC, helping protect electrical installations against severe prospective fault currents.
The PR231/P-I electronic release provides instantaneous short-circuit protection, with an adjustment range of 800–8000 A. Combined with the fixed three-pole construction and front terminals, the breaker is well suited to integration into industrial switchboards, distribution panels and other fixed power-distribution assemblies.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and feeder protection in electrical switchboards.
- Manufacturing and process-industry electrical installations.
- Commercial and infrastructure distribution assemblies.
- Transformer and installation protection.
- High-current machinery and plant distribution systems.
- Fixed switchgear requiring high short-circuit breaking capacity.
