Description

The DAM1 series electronic type Moulded Case Circuit Breaker (MCCB) is designed for reliable performance at 400V/415V. Unlike traditional thermal-magnetic breakers, this high-quality MCCB employs an electronic over-current release mechanism, which enhances its precision and responsiveness. This advanced design ensures that the breaker can effectively manage overcurrent conditions while safeguarding electrical systems.

Utilizing a microprocessor for control, the MCCB guarantees effective operation even under adverse conditions. It allows for wide-ranging customization, including rated and instant opening current adjustments, providing flexibility for various applications. Importantly, this electronic circuit breaker remains unaffected by ambient temperature variations, ensuring consistent performance.

Key Advantages:

• Wide current range from 100A to 1600A (AC)
• Compact dimensions for versatile installation
• Adjustable thermal setting (40-100%)
• Adjustable magnetic setting (1.5-12 times)
• Includes a push-to-trip button and separate main and arcing contacts
• Compatible with a wide range of accessories

Additional Information

Working Principle: The MCCB operates through manual or electric closing of the main contact, which is then locked into position by a free release mechanism. The overcurrent trip coil and thermal trip element are connected in series with the main circuit for effective overload protection.
