Features and benefits:

• High breaking capacity of 75 kA at 690 V AC makes it suitable for high-power industrial networks.
• Thermal-magnetic TM-D trip unit provides both overload (thermal) and short-circuit (magnetic) protection in a single device.
• Adjustable long-time pick-up (0.7...1 x In) allows fine-tuning of overload protection to match the connected load.
• Suitable for isolation duty conforming to EN/IEC 60947-2, enabling use as a main disconnecting device.
• Five auxiliary slots support optional add-on modules for signalling, remote control, or earth-leakage protection.
• Wide operating temperature range (-25...70 °C) and pollution degree 3 rating suit harsh industrial environments.

Applications:

• Main and sub-distribution switchboards in industrial facilities with high available fault currents.
• Protection of outgoing feeder circuits in medium and large power distribution panels.
• Motor feeder protection in industrial automation and process control installations.
• Applications requiring isolation capability on 690 V AC three-phase networks.
• Marine and heavy-industry installations requiring Marine and EAC certified equipment.
