1SDA062715R1 ABB T7V 800 PR232/P LSI 4P 800 A Circuit Breaker

Why Choose the ABB 1SDA062715R1 T7V 800 Circuit Breaker?

The ABB 1SDA062715R1 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 PR232/P LSI In=800A 4P F F, it combines an 800 A rated current with ABB's PR232/P electronic trip unit and high short-circuit interruption capability.

The PR232/P electronic trip unit provides LSI protection, covering long-time overload, short-time short-circuit and instantaneous short-circuit conditions. Its overload protection can be adjusted across 0.4–1 × In, while the short-circuit protection provides an adjustable range of 1.5–12 × In, allowing the breaker protection characteristics to be coordinated with the requirements of the electrical distribution system.

The 1SDA062715R1 is a four-pole fixed circuit breaker with front terminals and provides an ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC. Its combination of high breaking performance, adjustable electronic protection and four-pole switching makes it particularly suitable for industrial switchboards, main distribution boards and high-current feeder applications.

PR232/P LSI Electronic Circuit Protection

The PR232/P electronic trip unit provides adjustable protection for low-voltage distribution systems. Its long-time function protects conductors and connected equipment against sustained overloads, while the short-time and instantaneous functions respond to higher fault currents and severe short-circuit conditions. The adjustable protection ranges enable the breaker to be coordinated with downstream devices and the characteristics of the protected circuit.

Combined with the T7V high-breaking-capacity platform, the ABB 1SDA062715R1 can interrupt prospective fault currents up to 150 kA at 380–415 V AC. The four-pole configuration also provides selectable neutral protection, making the breaker particularly suitable for three-phase and neutral distribution systems requiring comprehensive electronic overcurrent protection.

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.
