ABB S201-K8 interruptor automático, 1 polo, curva K, 8 A, 6 kA, 230/400 V AC 2CDS251001R0407

The ABB S201-K8 stands out with its K tripping characteristic, which is specifically tailored for protecting circuits with high inrush currents, such as motors, transformers, and control circuits. Unlike standard B or C curve breakers, the K curve allows for higher instantaneous tripping thresholds, preventing nuisance tripping while still providing robust short-circuit protection. This 1-pole MCB is part of the System pro M compact S200 series, known for its reliable performance and space-saving design.

Highlights

• K tripping characteristic for high inrush current applications
• Rated current of 8 A with 6 kA breaking capacity
• Suitable for DIN rail mounting with front-side wiring
• Compact 1-pole design for efficient panel space utilization

In daily use

Installation is straightforward thanks to the screw terminals that accommodate conductors from 0.75 to 25 mm². The breaker operates reliably across a wide temperature range from -25°C to +55°C, making it suitable for various environments. With an electrical endurance of 10,000 AC cycles and mechanical endurance of 20,000 cycles, it ensures long-term dependability in industrial and commercial settings.
