TSM4E series electronic type moulded case circuit breaker is applied for circuit of rated insulating voltage up to 1000V, rated operation voltage up to 400V, rated operation current up to 800A, AC 50/60Hz, for usage of infrequent transfer of the circuit and infrequent starting of the motor as well. The breakers protect the circuit and devices in the circuit against being damaged by means of inverse time long time delay overload proection, inverse time short time delay short circuit proection, short time delay short circuit protection, short circuit protection and under voltage protection. The products comply with IEC60947-2.
Five options of tripping characteristic are available, user can adjust the current according to the required loading;
The electronic tripper is energized by the circuit breaker itself.
Alarm indication: when loaded current is bigger than the preset current, the LED indicator on the front panel indicates yellow color immediately.
Overload indication: when loaded current is bigger than the rectified current, the LED indicator on the front panel indicates red color immediately.
