SE-100/330, SE-250/330, SE-600/330 series marine plastic shell circuit breakersDetailed product description：

SE-100/330, SE-250/330, SE-600/330 series marine plastic shell circuit breakers

meet the standard

SE series circuit breakers are suitable for AC 50Hz, rated insulation voltage of 500V, rated working voltage of 400V, and rated current up to 630A (800A). They are generally used for power distribution and can also be used to protect motors. Under normal circumstances, circuit breakers can be used for infrequent switching of lines and infrequent starting of motors.

Circuit breakers for power distribution are used in the distribution network to distribute electrical energy. And it can be used as overload, short circuit, and undervoltage protection for lines and power equipment.

Circuit breakers for protecting electric motors are used in distribution networks for starting and disconnecting squirrel cage motors, as well as for overload, short circuit, and undervoltage protection of motors.

The SE series circuit breakers comply with the current national standards GB14048.2 "Low Voltage Switchgear and Control Equipment - Low Voltage Circuit Breakers" and GB14048 "Low Voltage Switchgear and Control Equipment - Part 2 Circuit Breakers". In order to facilitate some users to adopt SE series circuit breakers in a timely manner after the 35 year old DZ10 series circuit breakers are phased out, the external dimensions and installation dimensions of SE series circuit breakers are specially designed to be exactly the same as those of DZ10 series.
