Product Description

Introduction
DAB6-63 are intended for safeguarding distribution and group systems with varying loads, ensuring optimum performance across different applications:
- Electric appliances, lighting - V characteristic switches; suitable for standard electrical devices and lighting installations.
- Drives with moderate starting currents (compressor, fan group) - C characteristic switches; ideal for equipment with moderate power demands.
- Drives with high starting currents (hoisting mechanisms, pumps) - D characteristic switches; perfect for heavy-duty machinery requiring high starting power.
Miniature Circuit Breaker DAB6-63 is highly recommended for electrical distribution panels in both residential and public buildings, offering dependable protection and reliability.

Advantages

• Dual short circuit protection mechanisms for enhanced safety.
• Operates efficiently across a broad temperature range from -40 to +50° С, making it versatile for various environments.
• Features an updated, wider engagement lever, enhancing the contact area for better performance.
• Terminal clamps with notches reduce thermal losses and improve the mechanical stability of connections, ensuring robust and secure installations.
