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

• The High Breaking Capacity 10ka MCB B/C/D Asta Approved Miniature Circuit Breaker offers two superior types of overcurrent protection, blending both thermal and electromagnetic technologies. This ensures unparalleled safety and reliability for your electrical systems.
• Featuring an independent contact position indicator, the circuit breaker provides an added layer of assurance by clearly indicating the current operational status for enhanced safety and user convenience.
• Equipped with a DIN rail latch boasting a double fixed position, the circuit breaker ensures a secure and steadfast installation, contributing to a robust and reliable electrical infrastructure.
• Designed to excel in diverse environments, it operates efficiently across an impressive temperature range from -40 to +50° С, making it adaptable to various climatic conditions.
• With a wide engagement lever and enhanced contact area, this circuit breaker ensures optimal performance and ease of operation, providing a seamless user experience.

The notches on terminal clamps are engineered to significantly reduce thermal losses while boosting the mechanical stability of the connection, ensuring durability and longevity of the system.
