Why Choose the ABB T5V-HA630 PR221DS-LS/I In630 4p FF 800V AC Circuit Breaker?
The ABB T5V-HA630 PR221DS-LS/I In630 4p FF 800V AC 1SDA083667R1 is a 4-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax T range, engineered for demanding AC power distribution systems operating at 800 V AC. With a 630 A rated current and ABB's V short-circuit performance level, it provides high-current circuit protection in industrial, photovoltaic and other specialised 800 V AC installations.
Protection is provided by an electronic PR221DS-LS/I solid-state trip unit. Its LS/I protection functions provide long-time overload protection, short-time short-circuit protection and instantaneous short-circuit protection, giving the breaker electronic protection suited to power distribution applications where coordinated fault protection is required.
The breaker is supplied as a fixed, 4-pole unit with front terminals. At 800 V AC, it provides an ultimate short-circuit breaking capacity (Icu) of 32 kA and a service short-circuit breaking capacity (Ics) of 16 kA, together with a rated insulation voltage of 1,000 V and rated impulse withstand voltage of 8 kV.

Electronic LS/I Protection for 800 V AC Distribution
The PR221DS-LS/I electronic trip unit provides multiple protection functions within the circuit breaker. The L function provides long-time protection against sustained overloads, while the S function addresses short-time short-circuit conditions and can support improved coordination within a distribution system. The I function provides instantaneous protection against severe short-circuit faults.
Combined with a 630 A rated current, four-pole construction and an ultimate breaking capacity of 32 kA at 800 V AC, the 1SDA083667R1 is well suited to high-current 800 V AC distribution. ABB specifies this breaker for use on 800 V IT networks, extending its suitability to specialised industrial and power-generation applications.
