DAM2 series molded case circuit breakers are advanced devices developed using international technology, featuring compact design, high breaking capacity, short arc-over distance, and shakeproof properties. These breakers are ideal for both land and marine applications, providing reliable protection and power distribution.
Applications include AC 50Hz/60Hz distribution networks with rated working voltage up to 690V and rated current up to 1250A. They protect circuits and equipment from damage due to overload, short-circuit, under-voltage, and other faults. Additionally, they support infrequent circuit conversion and motor starting with overload, short-circuit, and under-voltage protection.
DAM2 circuit breakers can be mounted vertically or horizontally and are suitable for isolation, meeting IEC60947-2 standards. Normal operating conditions include ambient air temperature from -5°C to +40°C, altitude up to 2000m, and pollution degree 3.
Selection is based on pole type, rated current, wiring method, over-current release pattern, and accessories. Pole types include A, B, and C with varying N-pole configurations. Rated currents range from 6A to 1250A across different models like DAM2-63, DAM2-100, DAM2-250, DAM2-400, DAM2-630, DAM2-800, and DAM2-1250.
Accessories include internal components such as shunt release, under-voltage release, auxiliary contact, and alarm contact, as well as external components like manual and electric operating mechanisms. Technical parameters detail instantaneous action characteristics, rated values, and breaking capacities for different models and applications.
For distribution, the instantaneous action characteristic is set at 10In±20%, while for motor protection, it is 12In±20%. Inverse time breaking action characteristics are specified for both power distribution and motor protection scenarios.
Internal accessories like shunt release and under-voltage release have specific voltage ratings and operational ranges. External accessories include motor operating mechanisms and manual handles with detailed installation dimensions.
A fast selection table assists in configuring the breaker based on model features, frame rated current, breaking capacity, operation mode, poles, release type, accessories, application, and current rating. Example configurations are provided for clarity.
Working principle involves manual or electric closing of main contacts, locked by a free release mechanism. Over-current and thermal trip elements are series-connected to the main circuit, while under-voltage release is parallel-connected to the power supply.
