Why Choose the ABB T7V 800 1SDA062734R1 Circuit Breaker?
The ABB 1SDA062734R1 is a high-performance SACE Tmax T7V moulded case circuit breaker (MCCB) designed for protection and control of demanding low-voltage power distribution systems. Identified by ABB as T7V 800 PR332/P LSI In=800A 4p F F M, it combines an 800 A rated uninterrupted current with the advanced PR332/P electronic trip unit, four-pole construction and a stored-energy operating mechanism.
The T7V performance level provides an ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC, making this breaker suitable for installations with very high prospective fault currents. Its PR332/P LSI electronic trip unit provides long-time overload (L), short-time short-circuit (S) and instantaneous short-circuit (I) protection, allowing effective protection coordination within complex electrical distribution networks.
This configuration is a four-pole, fixed circuit breaker with front terminals and is rated for operation up to 690 V AC. The stored-energy operating mechanism and optional motor-drive capability make the 1SDA062734R1 particularly suitable for industrial switchboards and automated power distribution systems requiring high interruption performance and electrically controlled operation.

Advanced LSI Protection for Industrial Power Distribution
Moulded case circuit breakers such as the ABB SACE Tmax T7V protect electrical distribution systems against potentially damaging overload and short-circuit currents. The 1SDA062734R1 combines an 800 A rating with an ultimate breaking capacity of 150 kA at 380–415 V AC, providing robust interruption performance for industrial installations with exceptionally high prospective fault levels.
The integrated PR332/P LSI electronic trip unit provides adjustable long-time, short-time and instantaneous protection. Short-time protection can assist with selective coordination between protective devices, while the four-pole construction supports three-phase four-wire distribution systems where the neutral conductor forms part of the switching arrangement. The stored-energy mechanism also supports applications requiring controlled or remotely automated breaker operation.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-main electrical switchboards.
- Three-phase four-wire distribution systems.
- Automated and remotely controlled switchboards.
- Manufacturing and process plant power systems.
- High-current feeder and cable protection.
- Installations requiring selective short-circuit protection.
- OEM switchgear and electrical panel assemblies.
