Why Choose the ABB T7V 800 1SDA062720R1 Circuit Breaker?
The ABB 1SDA062720R1 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 LSIRc In=800A 4p F F, it combines an 800 A rated uninterrupted current with the advanced PR332/P-LSIRc electronic trip unit and a four-pole fixed configuration.
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-LSIRc electronic trip unit combines adjustable overload, short-time and instantaneous short-circuit protection with residual-current protection capability for comprehensive circuit protection.
This configuration is a four-pole, fixed circuit breaker with front terminals and a manual lever operating mechanism. Rated at 800 A with an overload adjustment range of 320–800 A, the 1SDA062720R1 is particularly suitable for industrial switchboards, main distribution panels and three-phase four-wire systems requiring high breaking performance and residual-current protection.

Comprehensive LSIRc 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 conditions. The 1SDA062720R1 combines an 800 A current rating with an ultimate breaking capacity of 150 kA at 380–415 V AC, providing robust interruption performance for installations with exceptionally high prospective fault currents.
The integrated PR332/P-LSIRc electronic trip unit adds residual-current protection capability to adjustable long-time, short-time and instantaneous protection. Combined with its four-pole construction, this makes the breaker particularly suitable for three-phase four-wire distribution systems where high-performance circuit protection, neutral switching and residual-current fault detection are required.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-main electrical switchboards.
- Three-phase four-wire distribution systems.
- Manufacturing and process plant power systems.
- High-current feeder and cable protection.
- Distribution systems requiring residual-current protection capability.
- OEM switchgear and electrical panel assemblies.
