Product Description

Introduction

DAB5-63 are designed to offer unparalleled protection for distribution and group systems across a variety of load types:
- electric appliances, lighting - V characteristic switches, ensuring reliability and performance;
- drives with moderate starting currents (compressor, fan group) - C characteristic switches, providing efficient operation;
- drives with high starting currents (hoisting mechanisms, pumps) - D characteristic switches, offering robust support;
Miniature circuit breaker DAB5-63 are ideal for integration into electrical distribution panels within residential and public infrastructures, enhancing safety and efficiency.


Advantages
 

• Dual modes of short circuit protection, ensuring comprehensive safety.
• Operates efficiently across a vast temperature spectrum from -40 to +50° C, adaptable to diverse environments.
• Enhanced, broader engagement lever with a superior contact area for improved functionality.
• Innovative notches on terminal clamps minimize thermal losses and elevate the mechanical robustness of connections.
