Why Choose the ABB T7V 800 PR332/P-LI 800 A 3P Fixed Circuit Breaker?
The ABB 1SDA062725R1 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-LI electronic protection release. It is engineered for demanding low-voltage power-distribution systems requiring dependable overload and instantaneous short-circuit protection.
The T7V 800 offers high fault-interruption performance, including a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC. Its rated operational voltage is 690 V AC, with a rated insulation voltage of 1000 V and rated impulse withstand voltage of 8 kV.
The PR332/P-LI solid-state release provides long-time overload and instantaneous short-circuit protection. Combined with the stored-energy operating mechanism, fixed mounting and front main-circuit terminals, this T7V configuration provides a robust solution for high-current industrial and commercial switchboards.

High-Performance LI Protection with Stored-Energy Operation
The ABB PR332/P-LI electronic release combines long-time and instantaneous protection functions. Long-time protection responds to sustained overload conditions, while instantaneous protection provides rapid circuit interruption when severe short-circuit currents occur. The overload setting is adjustable across 320–800 A, while the instantaneous short-circuit setting covers 1200–12000 A.
Combined with the T7V breaker's 150 kA ultimate breaking capacity at 400 V AC and its stored-energy operating mechanism, the 1SDA062725R1 provides a high-performance solution for distribution systems where substantial fault interruption capability and electronic circuit protection are required.
Typical Applications
- Industrial low-voltage power-distribution switchboards.
- Main distribution boards and high-current feeders.
- Three-phase commercial and infrastructure distribution systems.
- Installations with high prospective short-circuit currents.
- Power-distribution circuits requiring electronic overload and instantaneous protection.
- Fixed MCCB installations requiring stored-energy circuit-breaker operation.
