1SDA062730R1 ABB T7V 800 PR231/P LS/I 4P 800 A FFM Circuit Breaker

Why Choose the ABB 1SDA062730R1 T7V 800 Circuit Breaker?

The ABB 1SDA062730R1 is a high-performance four-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax T7 range, engineered for demanding low-voltage power distribution applications. Identified as T7V 800 PR231/P LS/I In=800A 4P F F M, it combines an 800 A rated current with ABB's PR231/P electronic trip unit and the high short-circuit interruption performance of the T7V platform.

The PR231/P LS/I electronic trip unit provides adjustable overload and short-circuit protection for power distribution circuits. The overload setting can be adjusted from 0.4–1 × In, equivalent to 320–800 A, while the short-circuit release provides an adjustable range of 1.5–12 × In. Neutral protection can also be selected at OFF, 50% or 100% for the four-pole configuration.

The 1SDA062730R1 is supplied as a four-pole fixed circuit breaker with front terminals and a stored-energy operating mechanism. Its T7V construction provides an ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC, making it particularly suitable for industrial switchboards, main distribution assemblies and high-current feeder circuits with substantial prospective fault levels.

PR231/P LS/I Electronic Protection and Stored-Energy Operation

The PR231/P LS/I electronic trip unit monitors circuit current and provides adjustable protection against overload and short-circuit conditions. Its overload setting range of 320–800 A allows the protection threshold to be matched to the protected circuit, while the adjustable short-circuit function enables rapid interruption of higher fault currents and supports coordination with other protection devices.

The stored-energy operating mechanism provides controlled breaker operation and can be combined with an optional motor drive where electrically operated switching is required. Together with the T7V platform's 150 kA Icu at 380–415 V AC, the four-pole construction and selectable neutral protection make the ABB 1SDA062730R1 well suited to demanding three-phase and neutral power distribution systems.

Typical Applications

• Industrial low-voltage main distribution boards.
• High-current feeder and sub-main protection.
• Four-pole three-phase and neutral distribution systems.
• Manufacturing and process plant switchboards.
• Commercial building electrical distribution.
• Infrastructure and utility distribution assemblies.
• Installations with high prospective short-circuit currents.
