Suitable for AC 50Hz and 60Hz applications, this circuit breaker has an insulation voltage rating of 800V (500V for the MLM1-63 model) and a working voltage rating of 690V (400V and below for the MLM1-63 model). With a rated working current of up to 1250A, the MLM1 is ideal for infrequent switching and motor starting in circuits rated up to 630A. This versatility makes it a valuable component in protecting circuits and power equipment from potential damage.
Designed with safety and efficiency at its core, the MLM1 circuit breaker provides comprehensive overload, short-circuit, and undervoltage protection. This ensures your electrical system is protected from unexpected surges and faults. The MLM1 series offers three different models: L-type (standard), M-type (high-breaking), and H-type (high-breaking), meeting various application requirements based on their rated ultimate short-circuit breaking capacity. Its compact size, high breaking capacity, and short-arc characteristics make it suitable for both land-based installations and marine environments, ensuring reliable operation wherever it is deployed.
The MLM1 circuit breaker is designed to operate under normal operating conditions within an ambient temperature range of -5°C to +40°C (standard products are rated for up to +45°C). It can be installed at altitudes up to 2,000 meters, with relative humidity not exceeding 50% at the highest temperature. The circuit breaker is designed to withstand a wide range of environmental challenges, including humid air, salt spray, oil mist, mold, and even nuclear radiation. This resilience ensures the MLM1’s reliable operation in a wide range of conditions, making it a dependable choice for critical applications.
Furthermore, the MLM1 circuit breaker features a simple, easy-to-use design and supports both vertical and horizontal installation. It can withstand tilts of up to +/-22.5° and operate reliably in earthquakes up to 4g. However, the circuit breaker must be installed in an area free from explosion hazards, conductive dust, and excessive moisture to ensure optimal performance and service life. The MLM1 circuit breaker complies with international standards such as IEC 60947-2 and GB 14048.2, guaranteeing quality and safety in electrical protection. Choosing the MLM1 molded case circuit breaker provides a reliable, efficient, and safe solution for your power needs.
