1SDA062705R1 ABB T7V 800 PR231/P-I 800 A 3-Pole MCCB

Why Choose the ABB T7V 800 PR231/P-I 1SDA062705R1 Circuit Breaker?

The ABB 1SDA062705R1 is a high-performance Tmax T7V 800 moulded case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage electrical distribution systems. This configuration combines an 800 A rated current, three-pole construction and an ABB PR231/P-I solid-state electronic trip unit for adjustable instantaneous short-circuit protection.

As part of the ABB SACE Tmax T7 series, the T7V 800 is engineered for installations requiring exceptionally high fault-breaking performance. The V performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC, while the circuit breaker is suitable for rated operational voltages up to 690 V AC.

The 1SDA062705R1 is supplied as a three-pole fixed circuit breaker with front terminals and a lever operating mechanism. Its PR231/P-I electronic release has an adjustable instantaneous short-circuit setting, making this configuration particularly suitable where high-capacity short-circuit protection is required in industrial switchboards, distribution assemblies and power systems.

High-Breaking-Capacity Protection for Power Distribution

The ABB Tmax T7 platform is designed for high-current low-voltage distribution systems where compact circuit protection and substantial fault interruption capability are required. The T7V performance level delivers an ultimate breaking capacity of 150 kA at 380–415 V AC, making this breaker suitable for installations with very high prospective short-circuit currents.

The PR231/P-I electronic trip unit provides adjustable instantaneous short-circuit protection, with an adjustment range of 800–8000 A. Combined with its fixed three-pole construction, front terminals and manual lever operation, the T7V 800 provides a robust protection solution for industrial switchboards and high-capacity distribution equipment.

Typical Applications

• Industrial low-voltage power distribution systems.
• Main and feeder protection in electrical switchboards.
• Installations with high prospective short-circuit currents.
• Manufacturing and process-industry electrical systems.
• Commercial and infrastructure power distribution.
• High-current machinery and plant distribution systems.
• Fixed switchgear requiring very high short-circuit breaking capacity.
