Why Choose the ABB T7V 800 PR332/P-LSI 800 A 3P Fixed Circuit Breaker?
The ABB 1SDA062726R1 is a SACE Tmax T7V moulded-case circuit breaker rated at 800 A, supplied in a 3-pole fixed configuration with front terminals, a stored-energy operating mechanism and an ABB PR332/P-LSI electronic protection release. It is designed for demanding low-voltage power-distribution systems requiring adjustable overload and short-circuit protection.
The T7V 800 provides high fault-interruption performance with a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC. It has a rated operational voltage of 690 V AC, a rated insulation voltage of 1000 V and a rated impulse withstand voltage of 8 kV.
The PR332/P-LSI solid-state release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. Combined with its stored-energy operating mechanism, fixed mounting and front main-circuit connections, the 1SDA062726R1 provides a robust protection solution for high-current industrial, commercial and infrastructure switchboards.

- Main distribution boards and high-current feeders.
- Three-phase commercial and infrastructure distribution systems.
- Transformer and generator protection applications.
- Installations with high prospective short-circuit currents.
- Fixed MCCB installations requiring LSI electronic protection and stored-energy operation.
