1. It must select pulse type in the automatic control system.
2. power-on time of the intermittent type cannot be greater than 2 s, pulse frequency of the pulse type cannot be more than 5 times/min, or the components are easily burnt.
3. Ensure that the product is in the energy storage state so that the closed electromagnet may be energized;
4. If the product is not closed after a single power-on for 15s, must disconnect the power on the closed electromagnet immediately.

• Shunt release (ST)
  The power-on time cannot be greater than 2 seconds/ time, and the power-on frequency cannot be greater than 5 times / minute.
  a. The shunt release should be used except for special products where the circuit breaker must be directly disconnected manually;
  b. The shunt release could operate within 10 meters to break the circuit breaker.

• Undervoltage release (UVT)
  Under-voltage release (UVT) (Optional, the power must be turned on before the circuit breaker is closed)
  The under-voltage release has instantaneous operation and delayed operation:

  Under-voltage delay release.
   
  Notes:

1. Inm=1600A under-voltage delay does not require an external delay controller. The power-off operation is an instantaneous operation. There is no zero-voltage delay function;
2. Inm=6300A under-voltage delay does not require an external under-voltage delay controller. There is a delay function for low voltage and power off;
3. Inm=2000A~4000A under-voltage delay requires an external delay controller. There is a delay operation when the power is off. There is a zero-voltage delay function.

   The under-voltage will not operate when the voltage returns to 85% Ue and higher, within 1/2 delay time.
