The ABB T4V-HA 250 TMA 200-2000 3P F F 800V AC, order code 1SDA083662R1, is a three-pole moulded case circuit breaker (MCCB) from the ABB Tmax range, engineered for high-voltage AC distribution applications. Built on the T4V-HA 250 A frame, it combines thermomagnetic protection with an operating voltage of 800 V AC.
This circuit breaker has a 200 A rated current and incorporates an ABB TMA thermomagnetic release. Its thermal protection is adjustable from 0.7–1 × In, corresponding to 140–200 A, while the magnetic protection is adjustable from 5–10 × In, corresponding to 1000–2000 A.
The 1SDA083662R1 is supplied as a fixed three-pole circuit breaker with front terminals. At its rated operational voltage of 800 V AC, it provides an ultimate short-circuit breaking capacity of 25 kA and a service short-circuit breaking capacity of 12 kA, making it suitable for demanding industrial and specialised power-distribution installations.
The ABB TMA release combines adjustable thermal overload protection with adjustable magnetic short-circuit protection. On this 200 A model, the thermal setting can be adjusted from 140–200 A, while the magnetic setting can be configured from 1000–2000 A, allowing the breaker protection to be coordinated with the requirements of the protected circuit.
The T4V-HA platform is engineered for operation at 800 V AC, where suitable insulation and fault-interruption performance are essential. With 25 kA Icu, 12 kA Ics, fixed mounting and front terminals, the 1SDA083662R1 provides a practical solution for demanding high-voltage AC distribution equipment.
