  • Ambient Operating Temperature: Typically -25°C to +70°C

2. Key Features

  • Designed for compact low-voltage power distribution with high performance.

  • 50kA breaking capacity makes it suitable for industrial and commercial installations with moderate fault levels.

  • Equipped with a fixed TMD trip unit for reliable thermal and magnetic protection.

  • Compact dimensions for space-saving in switchboards and distribution panels.

  • Compression lugs and busbar-ready terminals provide flexibility in wiring and installation.

  • Front-facing terminal access for easy maintenance and fast replacement.

  • Supports modular add-ons such as auxiliaries, rotary handles, and communication accessories.

3. Applications

  • Suitable for main circuit protection in low-voltage electrical distribution systems.

  • Ideal for industrial panels, machinery, commercial buildings, and energy infrastructure.

  • Can be used to protect feeders, lighting systems, HVAC equipment, and general power loads.

  • Offers protection for applications where a high breaking capacity is needed but extreme fault levels (above 50kA) are not expected.
