Why Choose the ABB T5V-HA630 PR221DS-LS/I In630 3p FF 800V AC Circuit Breaker?
The ABB 1SDA083656R1 is a high-performance three-pole moulded case circuit breaker (MCCB) designed for demanding low-voltage AC distribution systems operating at up to 800 V AC. Part of ABB's Tmax T high-voltage AC circuit breaker range, the T5V-HA630 combines a 630 A rated current with an electronic PR221DS-LS/I trip unit for dependable protection of high-power electrical installations.
The integrated PR221DS-LS/I solid-state release provides long-time, short-time and instantaneous protection functions, enabling the breaker to protect conductors and distribution equipment against overload and short-circuit conditions. The electronic release provides a versatile protection platform for applications requiring more sophisticated protection characteristics than a conventional thermomagnetic trip unit.
Designed as a fixed three-pole circuit breaker with front terminals, the T5V-HA630 has an ultimate short-circuit breaking capacity of 32 kA at 800 V AC and a service breaking capacity of 16 kA at 800 V AC. Its 1000 V insulation voltage, robust mechanical endurance and IEC/CCC configuration make it particularly suitable for specialised industrial and high-voltage AC distribution systems.

Advanced Electronic Protection for 800 V AC Distribution
The ABB T5V-HA630 is engineered for electrical systems operating at higher AC voltages than conventional low-voltage distribution networks. Its 800 V AC operating voltage, 1000 V insulation rating and 32 kA Icu provide the electrical characteristics required for specialised industrial and energy applications while retaining the compact construction of a moulded case circuit breaker.
Unlike TMA thermomagnetic versions of the T5V-HA range, this 630 A model incorporates ABB's PR221DS-LS/I electronic release. Long-time, short-time and instantaneous protection functions provide coordinated protection against overloads and different levels of short-circuit current, making the breaker suitable for distribution systems where dependable electronic protection and high current capacity are required.
Typical Applications
- Industrial 800 V AC power distribution systems.
- High-current switchboards and distribution panels.
- Renewable-energy and photovoltaic AC distribution equipment.
- Industrial plants and process installations.
- High-power machinery and electrical infrastructure.
- OEM power distribution and protection assemblies.
