Product Description

Introduction

DAB5-63 are specially designed to safeguard distribution and group systems across a wide range of load requirements:
- Electric appliances, lighting systems - engineered with V characteristic switches for optimal performance;
- Drives with moderate starting currents (such as compressor and fan groups) - utilize C characteristic switches for superior functionality;
- Drives with high starting currents (including hoisting mechanisms and pumps) - equipped with D characteristic switches for enhanced operation;
Miniature circuit breaker DAB5-63 are highly recommended for seamless integration in electrical distribution panels within residential and public buildings, ensuring reliable performance.


Advantages
 

• Dual short circuit protection mechanisms offer unparalleled safety.
• Operates across a vast temperature spectrum from -40 to +50° С, ensuring reliable performance in diverse environments.
• Enhanced engagement lever design provides a wider contact area, fostering improved connectivity and reliability.
• Innovative notches on terminal clamps effectively reduce thermal losses while significantly enhancing mechanical stability of the connection.
