Product Description

 auxiliary switches are mainly used as opening and closing signal control and interlocking protection contacts in the control circuits of electric operating mechanisms of various high-voltage circuit breakers and high-voltage isolating switches. They can also be used as transfer switches and combination switches.
Characteristic:
1. Adopting self-operated plane sliding contact, the movable contact is composed of two contact pieces, there is no fixed gap, no contact seat, so that the contact pressure of each pair of contacts can be consistent.
2. Adopting laminated structure, the number of contacts can be increased or decreased according to needs.
3. Small size, simple structure, flexible operation, safe and reliable.

 

Main features:

  • To control the DC contact of DC 220V/110V close coil or breaking coil, it could reach 20A when the breaking current is DC 220V.
  • The double-break bridging contact is made of silver alloy. Compared with the current auxiliary switch, it contacts directly, resists oxidation, and resists corrosion.
  • It is of simple structure and long lifetime. Being an ideal product, and it's also easy to use.

Application conditions

  • Ambient Temperature (-40ºC+40ºC)
  • Height above Sea Level (h≤2500m)
  • Mean relative air humidity in 24 hours (T≤95%)
  • Mean water vopour pressure in 24 hours (≤2.2Kpa)
  • Mean monthly relative humidity(≤90%)
  • Mean monthly water vopour pressure (≤1.8Kpa), includes the dew covered on the surface of the products, which is caused by the changes in temperature.
  • Acceleration (a ≤15m/s²)
