Rocker Switch with External Reset Function for High capacity Switching

  • Energy-saving reset function triggered with external signals.
  • Incorporates unique switching mechanism switching 20 A with excellent inrush-current durability.
  • Double-pole, double-throw (DPDT) contact.
  • Contact gap of 3 mm minimum.
  • UL and cUL standard approved. Conforms to EN standards. ■List of Models ■Ratings Note: 1. The non-inductive lamp load has an inrush current 10 times steady current. 2. The inductive load has a power factor of 0.4 minimum (AC). 3. The motor load has an inrush current 6 times steady current. The above ratings were tested under the following conditions: 1. Ambient temperature: 20 ±2 °C 2. Ambient humidity: 65 ±5 %RH 3. Switching frequency: 7 times/min. Reset Coil Note: 1. Current must not flow for more than 10 s, otherwise the performance of the coil may be affected. 2. If a semiconductor element is used to control the reset coil, the residual voltage caused by leakage current must be 2.4 VDC max.
