Why Choose the ABB 1SDA107582R1 XT6S 800 Circuit Breaker?
The ABB 1SDA107582R1, designated XT6S 800 TMA 630-6300 4p F F InN=100%In, is a four-pole fixed SACE Tmax XT6S moulded-case circuit breaker designed for low-voltage AC and DC power distribution applications. Built on ABB's XT6 800 A frame, this configuration has a rated current of 630 A, front terminals and a four-pole thermomagnetic TMA protection release.
The integrated TMA thermomagnetic trip unit provides adjustable overload and instantaneous short-circuit protection. ABB specifies a thermal current setting range of 0.7–1 × In, corresponding to approximately 441–630 A, together with an instantaneous magnetic protection range of 3150–6300 A. This allows the breaker to be adapted to the protection requirements of suitable feeders and distribution circuits.
The XT6S performance level provides an ultimate short-circuit breaking capacity of 50 kA at 415 V AC. This four-pole version also features a fully rated neutral at 100% of phase rated current, making it suitable for distribution systems where the neutral conductor must carry the full rated current of the breaker.

Adjustable Thermomagnetic Protection for Power Distribution
The ABB TMA trip unit combines thermal overload protection with magnetic short-circuit protection. The thermal element responds to sustained overcurrent conditions, while the magnetic element provides rapid tripping when high fault currents occur.
For the 1SDA107582R1, the thermal setting can be adjusted from approximately 441 to 630 A, while the instantaneous magnetic trip threshold can be set between 3150 and 6300 A. This makes the breaker suitable for high-current distribution applications where adjustable protection and a fully rated neutral are required.
Typical Applications
- Industrial low-voltage main and sub-distribution switchboards.
- Commercial building electrical distribution systems.
- Four-wire three-phase distribution circuits.
- Installations with significant neutral conductor loading.
- Manufacturing and process-industry power distribution.
- Applications requiring a fixed 630 A MCCB with adjustable thermomagnetic protection.
