Why Choose the ABB T7V 800 PR332/P-LI 800 A 3P Fixed Circuit Breaker?
The ABB 1SDA062709R1 is a SACE Tmax T7V moulded-case circuit breaker rated at 800 A, supplied in a 3-pole fixed configuration with front terminals and an ABB PR332/P-LI solid-state protection release. It is designed for demanding low-voltage distribution systems requiring dependable overload and instantaneous short-circuit protection.
The T7V 800 combines an 800 A rated uninterrupted current with a rated voltage of 690 V AC. Its V-performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC, 50 Hz, making it particularly suitable for installations with very high prospective fault currents.
The PR332/P-LI electronic release provides long-time overload and instantaneous short-circuit protection. Combined with fixed mounting, front main-circuit terminals and a lever operating mechanism, the 1SDA062709R1 provides a complete high-performance circuit-breaker solution for industrial and commercial switchboards.
