The DZ6 400Y 800V MCCB is a specialized Moulded Case Circuit Breaker designed specifically for isolator applications. Unlike traditional MCCBs, it is devoid of protection trip units, making it ideal for switching various loads such as UPS and battery banks. The DZ6 model allows local isolation near motor loads, incoming sub-distribution, and serves effectively as an isolator for bus couplers. Additionally, it can function as an automatic switch for various applications, including those involving VFDs (Variable Frequency Drives) and soft starters. With its wide range of overload settings starting from 0.25In, the DZ6 MCCB offers excellent flexibility and control. The device features effective short circuit settings with both delay and instantaneous options, inbuilt Earth fault protection, and adjustable instantaneous settings for enhanced performance. It also comes equipped with thermal memory and an option for defeat, ensuring reliable operation in case of unexpected trip conditions. For quick diagnostics, the MCCB includes separate LEDs for overload, short circuit, instantaneous, and earth fault indications, making it a dependable choice for industrial environments.
