Why Choose the ABB 1SDA100718R1 XT6N 800 TMA Circuit Breaker?
The ABB 1SDA100718R1 is a SACE Tmax XT6N moulded-case circuit breaker designed for dependable protection of low-voltage power distribution systems. Rated at 800 A, this fixed 3-pole circuit breaker combines an XT6 frame with ABB's TMA thermomagnetic trip unit and front terminals.
The TMA release provides thermal overload and magnetic short-circuit protection without requiring an external power supply. Its thermal protection setting is adjustable from 560–800 A, while the instantaneous magnetic trip setting covers 4000–8000 A, allowing the breaker characteristics to be matched to the protected circuit.
The XT6N version provides a rated ultimate short-circuit breaking capacity of 36 kA at 415 V AC. With a rated operational voltage up to 690 V AC, rated insulation voltage of 1000 V and rated impulse withstand voltage of 8 kV, the 1SDA100718R1 is suited to demanding industrial and commercial distribution applications.

Thermomagnetic Protection for Power Distribution
Thermomagnetic circuit breakers combine two complementary protection principles. The thermal element responds to sustained overload currents, while the magnetic element provides rapid operation during high-current short-circuit faults. This proven approach provides circuit protection without requiring auxiliary power for the trip unit.
The ABB XT6N 800 TMA allows the thermal threshold to be adjusted between 560 A and 800 A and the instantaneous magnetic threshold between 4000 A and 8000 A. These adjustable settings allow the 1SDA100718R1 to be coordinated with cables, feeders and downstream equipment in industrial and commercial distribution networks.
Typical Applications
- Industrial low-voltage distribution switchboards.
- Main and sub-main electrical distribution.
- High-current feeder and cable protection.
- Manufacturing and process plant electrical systems.
- Commercial and infrastructure power distribution.
- Transformer-fed distribution systems.
- Fixed ABB Tmax XT6 circuit breaker installations requiring thermomagnetic protection.
