Why Choose the ABB T7V 800 PR332/P LSIRc 800A Circuit Breaker?
The ABB 1SDA062728R1, designated T7V 800 PR332/P LSIRc In=800A 3p F F M, is a high-performance three-pole moulded-case circuit breaker (MCCB) designed for protection and control of demanding low-voltage electrical distribution systems. As part of the proven ABB Tmax T7 series, it combines an 800 A current rating with the advanced PR332/P LSIRc electronic trip unit for comprehensive circuit and residual-current protection.
The T7V version provides exceptionally high short-circuit interruption performance, with a rated ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC. The PR332/P LSIRc electronic release provides long-time, short-time and instantaneous overcurrent protection together with residual-current protection, enabling the breaker to protect installations against a broad range of electrical faults.
With a rated uninterrupted current of 800 A, a three-pole configuration, fixed installation and front terminals, the 1SDA062728R1 is well suited to main distribution boards, industrial switchboards and high-power infrastructure. Its stored-energy operating mechanism and motorisable design also provide flexibility for automated switching and control applications.

Advanced Protection for High-Power Distribution
Moulded-case circuit breakers such as the ABB Tmax T7 protect electrical distribution systems against overloads, short circuits and other potentially damaging fault conditions. The T7V 800 combines an 800 A continuous-current capability with very high short-circuit interruption performance, making it particularly suitable for installations with substantial prospective fault currents.
The PR332/P LSIRc electronic trip unit extends conventional overcurrent protection with residual-current functionality. Adjustable protection thresholds allow engineers to coordinate the breaker with upstream and downstream protection devices, while the fixed construction, front terminals and stored-energy mechanism support integration into sophisticated low-voltage switchboards.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power distribution systems.
- Manufacturing and process plants.
- Commercial and infrastructure electrical installations.
- Transformer and installation protection.
- High fault-level distribution networks.
- Automated power distribution and switching systems.
