DC rated protection for 250 V systems ensures safe and predictable switching of DC control circuits, reducing fault exposure in automation panels and enabling safer machine operation. The 1P device with a 1.6 A nominal rating provides precise current limitation for compact drives and logic circuits, improving uptime and protecting expensive control electronics. A C-curve tripping characteristic delivers balanced response to motor inrush and short-circuit currents, while a 10 kA short-circuit capacity offers robust margin for panel protection in synergistic AC/DC applications. DIN rail mounting on TH35-15 or TH35-7.5 rails simplifies installation, accelerates panel assembly, and supports scalable control architectures. Ring-Tongue terminals with captive screws enable secure, vibration-resistant connections for industrial environments, reducing maintenance time. The device’s energy efficiency is enhanced by a low power loss of 1.4 W and an ON/OFF contact indication, aiding diagnostics. Compliance with RoHS and REACH, IP20 protection, and a broad operating temperature range from -40 to +75 °C ensure reliable performance in demanding environments. Built-in durability features include 20,000 mechanical cycles, supporting long service life in high-use panels. With a compact footprint and 69 mm built-in depth, it fits into tight control cabinets while maintaining compatibility with standard panel designs and wiring practices.
