  • Description

The ABB 1SDA100521R1 is a Tmax XT5H 400 moulded case circuit breaker with a TMA thermomagnetic release, rated In 400 A across four poles with a fully rated neutral (InN=100%In). AC/DC current type and short-circuit performance class H give it a 70 kA breaking capacity at 415 V AC, with an adjustable 280-400 A thermal band and 2000-4000 A instantaneous trip range for coordinated protection.

Selection Notes

The 1SDA100521R1 pairs a fixed TMA thermomagnetic release, adjustable 280-400 A thermal and 2000-4000 A instantaneous trip, with AC/DC current type and a 750 V DC rating that the electronic Ekip Dip LS/I sibling does not carry, making it the choice for DC distribution or mixed AC/DC boards rather than pure AC switchboards. Short-circuit performance class H holds Icu and Ics at 70 kA at 415 V AC and 50 kA across 250-500 V DC in two-pole series connection. Fully rated neutral (InN=100%In) carries the full 400 A on the neutral pole, which four-wire systems with high neutral harmonic content require.
