The ABB 1SDA062721R1 is a high-performance Tmax T7V 800 moulded case circuit breaker (MCCB) designed for motor protection and demanding low-voltage electrical distribution applications. This configuration combines an 800 A rated current, three-pole construction and an ABB PR231/P-I solid-state electronic trip unit with adjustable instantaneous short-circuit protection.
As part of the ABB SACE Tmax T7 series, the T7V 800 provides very high fault-breaking performance for industrial switchboards and power systems. Its V performance level delivers a rated ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC, with operation supported on low-voltage systems up to 690 V AC.
The 1SDA062721R1 is a fixed, three-pole breaker with front terminals and a stored-energy motorisable operating mechanism. The PR231/P-I release provides adjustable instantaneous magnetic protection, making this version particularly suitable for motor circuits and applications where overload protection is provided separately.
The ABB Tmax T7V platform is designed for high-current installations where substantial short-circuit interruption capability is required. With an ultimate breaking capacity of 150 kA at 380–415 V AC, this T7V 800 configuration can interrupt severe prospective fault currents in demanding industrial electrical systems.
The PR231/P-I electronic trip unit provides adjustable instantaneous short-circuit protection over a range of 800–8000 A. This protection characteristic is particularly suited to motor applications in which the circuit breaker provides short-circuit protection while overload protection is coordinated through separate motor-protection equipment.
