Why Choose the ABB 1SDA100730R1 XT6N 800 TMA Circuit Breaker?
The ABB 1SDA100730R1 is a Tmax XT6N 800 moulded-case circuit breaker equipped with a TMA thermomagnetic trip unit. Designed in a fixed four-pole configuration with front terminals, it has a rated current of 800 A and provides dependable thermal overload and magnetic short-circuit protection for high-current low-voltage distribution systems.
As part of the ABB Tmax XT family, the XT6 combines compact moulded-case circuit-breaker construction with proven thermomagnetic protection technology. The TMA release responds thermally to sustained overload conditions and magnetically to high short-circuit currents, providing robust protection without relying on an electronic trip unit.
The XT6N 800 TMA 800-8000 4p F F InN=50%In combines an 800 A phase-current rating with a magnetic protection reference of 8000 A. Its four-pole construction incorporates neutral protection rated at 50% of the phase current, corresponding to 400 A, making it suitable for three-phase, four-wire distribution systems.

Reliable Thermomagnetic Protection for Power Distribution
Thermomagnetic circuit protection combines two complementary operating principles in a single trip unit. The thermal element responds to sustained overload currents that can overheat cables and equipment, while the magnetic element responds rapidly to high fault currents associated with short circuits.
The ABB 1SDA100730R1 combines this established protection principle with the high-current Tmax XT6 platform. Its four-pole arrangement and 50% neutral protection make it particularly useful for three-phase distribution systems where the neutral conductor requires protection at a reduced rating relative to the phase conductors.
Typical Applications
- Industrial low-voltage distribution switchboards.
- Main incoming and outgoing distribution circuits.
- Commercial building power-distribution systems.
- Manufacturing and process-industry installations.
- Infrastructure and utility distribution panels.
- Three-phase, four-wire circuits requiring reduced neutral protection.
