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

• Experience the dual advantage of safety with our innovative two types of overcurrent protection. The thermal and electromagnetic safeguards ensure that your electrical system remains secure and reliable under various conditions, offering peace of mind with uncompromised safety.
• Keep track of your circuit breaker's status effortlessly with our independent contact position indicator. This intuitive feature helps you instantly verify the breaker's operational state, enhancing maintenance efficiency and safety awareness.
• Our advanced DIN rail latch is crafted with a double fixed position, ensuring robust and secure installation. This feature significantly improves the stability and ease of mounting, making it an ideal choice for a wide range of applications.
• Designed to withstand the extremes, our circuit breaker operates seamlessly within a wide temperature range, from a frosty -40° to a scorching +50°C. This resilience makes it a perfect fit for diverse environments, guaranteeing performance and reliability.
• Benefit from our wide engagement lever, which offers an enhanced contact area. This improvement is engineered for optimal functionality, ensuring a more secure connection and facilitating smoother operation.

Our terminal clamps are ingeniously designed with notches that reduce thermal losses and enhance mechanical stability. This design innovation leads to improved efficiency and longer-lasting reliability in your electrical connections.
