Product Description

Introduction
 

Miniature circuit breakers NOVA DAB7-63 are intended for providing automatic power source cut-off under excess currents.They are recommended for use in group panels (apartment and floor) and distribution boards of residential, domestic, public and administrative buildings. 64 items per 8 rated currents ranging from 6 to 63 A. This MCB has been obtained ASTA, SEMKO,CB,CE certificate.

Advantages

• Engineered with dual overcurrent protection mechanisms - both thermal and electromagnetic - ensuring unmatched reliability and superior performance.
• Equipped with an independent contact position indicator for clear and precise status visibility, enhancing user confidence and safety.
• Features a DIN rail latch with an innovative double fixed position, providing secure, stable, and hassle-free installation.
• Designed to operate seamlessly across a broad temperature spectrum, ranging from -40 to +50° С, making it versatile for varied environmental conditions.
• Incorporates a wide engagement lever that enhances the contact area, ensuring robust and reliable connectivity.

Innovative notches on terminal clamps are designed to minimize thermal losses and significantly enhance the mechanical stability of each connection.
