Why Choose the ABB 1SDA062688R1 T7L 800 Circuit Breaker?
The ABB 1SDA062688R1 is a high-performance four-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax T7 range, engineered for demanding low-voltage power distribution and protection applications. Identified as T7L 800 PR332/P LSIRc In=800A 4P F, it combines an 800 A rated current with ABB's advanced PR332/P electronic trip technology.
The PR332/P electronic trip unit provides LSI protection, covering long-time overload, short-time short-circuit and instantaneous short-circuit conditions. The Rc residual-current protection function adds sensitive earth-leakage and residual-current protection, extending the breaker beyond conventional overcurrent protection for installations where residual-current monitoring is required.
The 1SDA062688R1 is configured as a four-pole fixed circuit breaker, making it suitable for three-phase and neutral distribution systems. The T7L platform combines high fault interruption performance with electronic protection, making this breaker well suited to main distribution, feeder and industrial switchboard applications.

PR332/P LSIRc Electronic and Residual-Current Protection
The PR332/P electronic trip unit monitors circuit current and initiates breaker tripping when configured protection thresholds are exceeded. Its L function protects against sustained overloads, the S function responds to short-time high-current faults, and the I function provides rapid interruption under severe short-circuit conditions.
The additional Rc function provides residual-current protection by detecting current imbalance associated with leakage to earth. Combined with the four-pole T7L 800 breaker platform, this gives the ABB 1SDA062688R1 a comprehensive protection profile for distribution systems requiring both overcurrent and residual-current fault protection.
Typical Applications
- Industrial low-voltage main distribution boards.
- High-current feeder and sub-main protection.
- Four-pole three-phase and neutral distribution systems.
- Installations requiring residual-current protection.
- Manufacturing and process plant switchboards.
