ABB 1SDA116389R1 Moulded Case Circuit Breaker - 100 kA

Three-pole design provides balanced protection across all phases. This improves fault isolation and reduces motor damage, contributing to higher uptime on conveyors and presses. It’s well-suited for integration into MCCB panels in automated production lines and packaging machines. Setting range of 224–320 A allows precise coordination with downstream protective devices. This minimizes nuisance trips and ensures selective tripping, which is essential for machine control circuits and power distribution boards with varying loads. High rated current and voltage ratings (320 A, 500 V AC / 250 V DC) enable direct connection to common industrial busbars and feeders, reducing the need for additional devices and simplifying wiring. The device offers Ics up to 100 kA (240 V AC) and Ui of 750 V, delivering strong short-circuit protection for demanding equipment. Low power loss (16.9 W) reduces panel heat, enabling denser layouts and lower cooling costs. With 15000 mechanical cycles, the MCCB supports long service intervals, lowering maintenance frequency and total cost of ownership. The front-terminal connection simplifies installation, testing, and field replacement, improving turnaround times during panel upgrades. Compliance to RoHS, REACH, CMRT, and TSCA supports regulatory reporting and supply-chain transparency, while WEEE classification (Category 5) aligns with sustainability programs. These characteristics make the ABB SACE DSP family a robust choice for modern power distribution in automotive, packaging, and process industries.
