The ABB 1SDA083681R1 is a high-performance SACE Tmax T5V-HA 400 UL moulded case circuit breaker (MCCB) designed for demanding low-voltage power distribution applications operating at up to 800 V AC. This four-pole circuit breaker combines a 300 A rated current with an ABB PR221DS-LS/I electronic trip unit to provide dependable overload and short-circuit protection.
As part of the ABB SACE Tmax T5 high-voltage AC range, the T5V-HA 400 is engineered for electrical installations requiring circuit protection at elevated AC operating voltages. The PR221DS-LS/I electronic release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection functions, allowing the breaker to protect distribution circuits and connected equipment against a range of overcurrent conditions.
With a rated current of 300 A, a 4-pole configuration and fixed installation with front terminals, the 1SDA083681R1 is suitable for compatible three-phase systems requiring switched or protected neutral arrangements. Its 800 V AC capability and T5V-HA construction make it particularly suited to specialised industrial and high-voltage AC distribution equipment.
Moulded case circuit breakers protect electrical distribution circuits by automatically interrupting current when overload or short-circuit conditions occur. Electronic trip units such as the ABB PR221DS provide configurable protection characteristics suited to demanding industrial power systems, helping protect cables, switchgear and connected electrical equipment.
The PR221DS-LS/I release fitted to the ABB 1SDA083681R1 provides long-time, short-time and instantaneous protection. Combined with the T5V-HA platform's 800 V AC capability and four-pole construction, this makes the breaker suitable for specialised power distribution systems requiring electronic protection at elevated AC operating voltages.
