Summary
SM1E Series Intelligent Plastic Case Circuit Breaker is one of the new type of circuit breakers developed and developed by our factory with advanced international design and manufacturing technology. Its rated insulation voltage is 800V, which is suitable for the rated working voltage of AC 50Hz/60Hz 400V, rated working current to 800A circuit for infrequent conversion and motor starting The plastic case circuit breaker has the functions of overload long delay inverse time limit, short circuit short delay inverse time limit, short circuit short delay fixed time limit, short circuit instantaneous and under voltage protection, and can protect the line and power supply equipment from damage.
The circuit breaker can be installed vertically (vertical) or horizontally (i.e. horizontal).
The circuit breaker can not be inverted into the line, that is, only 1, 3, 5 power lines, 2, 4, 6 to connect the load line.
The circuit breaker is suitable for isolation function.
The circuit breaker implements the following criteria:
* general principles of IEC60947-1 and GB14048.1 2000;
Additional requirements for IEC 60947-2 and GB14048.2 "2000" low voltage circuit breakers and appendix F circuit breakers with electronic overcurrent protection;
* IEC60947-4 and GB14048.4 contactors and motor starters;
IEC60947-5.1 and GB14048.5 electromechanical control circuit and electrical appliances.
