Why Choose the ABB 1SDA062729R1 T7V 800 Circuit Breaker?
The ABB 1SDA062729R1 is a high-performance four-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax T7 range, designed for demanding low-voltage power distribution applications. Identified as T7V 800 PR231/P I In=800A 4P F F M, it combines an 800 A rated current with a PR231/P electronic trip unit and the high fault-interruption performance of the T7V platform.
The PR231/P-I electronic trip unit provides adjustable instantaneous short-circuit protection, with a setting range of 800–8000 A. This protection characteristic makes the breaker particularly suitable where rapid interruption of high fault currents is required, while selectable neutral protection supports its use in four-pole three-phase and neutral distribution systems.
The 1SDA062729R1 is supplied as a four-pole fixed circuit breaker with front terminals and a stored-energy operating mechanism. It provides an ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC, making it suitable for industrial switchboards, main distribution assemblies and other installations with high prospective short-circuit currents.

PR231/P-I Electronic Short-Circuit Protection
The PR231/P-I electronic trip unit provides adjustable protection against high short-circuit currents. Its release can be set across an 800–8000 A range, allowing the instantaneous protection threshold to be matched to the characteristics of the protected circuit and coordinated with other protection devices within the distribution system.
Combined with the T7V high-breaking-capacity platform, the ABB 1SDA062729R1 can interrupt prospective fault currents up to 150 kA at 380–415 V AC. Its four-pole construction, selectable neutral protection, fixed front-terminal arrangement and stored-energy mechanism make it particularly suited to demanding three-phase distribution and switchboard applications.
Typical Applications
- Industrial low-voltage distribution boards.
- High-current feeder and distribution circuit protection.
- Four-pole three-phase and neutral distribution systems.
- Manufacturing and process plant switchboards.
- Commercial and infrastructure power distribution.
- Electrical installations with high prospective short-circuit currents.
