Product Description

Introduction
DAB6-63 Our DAB6-63 is meticulously designed to offer unparalleled protection for distribution and group systems, accommodating a diverse range of loads with precision:
- For electric appliances and lighting, it acts as V characteristic switches providing robust protection;
- For drives with moderate starting currents like compressors and fan groups, it serves as C characteristic switches for optimal functionality;
- For drives with high starting currents such as hoisting mechanisms and pumps, it functions as D characteristic switches for maximum efficiency;
Miniature Circuit Breaker DAB6-63 This exceptional miniature circuit breaker is ideal for installation in the electrical distribution panels of both residential and public buildings, ensuring safety and reliability.

Advantages

• Boasting two distinct types of short circuit protection, the DAB6-63 ensures superior safety and performance.
• It operates efficiently within a broad temperature range from -40 to +50° C, making it versatile for various environments.
• An updated, wider engagement lever enhances the contact area, ensuring secure and reliable operation.
• Ingenious notches on terminal clamps are designed to minimize thermal losses and enhance the mechanical stability of connections.
