ZXEV071-150A Non-polar epoxy package High Voltage DC Contactor Relay

1. Small and lightweight:Internally adopt reliable sealing technology and filled with nitrogen which arc colling ability is high. It can cut off high voltage DC in a short time.

2. High contact reliability:Due to the contact sealed in the nitrogen, therefore it will be not oxidized, also achieving the contact of the dustproof and waterproof.

3. Safety and reliable:Use the professional explosion-proof structure design,to achieve a high degree of security,adopt magnetic quenching helps to cut-off the DC load quickly.

4. Application:DC charging pile, electric vehicles, hybrid vehicles, battery charging and discharging system,Photovoltaic power generation system such as dc high voltage application.

  • 1. When installing the relay, to prevent bad connection, please use the flat washer, spring washer and nut fastening, the external connecting plates need closed to the nearest relay terminal part, ensure good connection. Incorrect connection sequence may can cause severe fever and lead to wires to melt or burn.

    2. The relay terminal have polarity difference, please do it correct connection according to the surface + - on the relay. If the connection polarity is reversed, the electrical performance will be greatly decreased.

    3. The contact parameters of the ratings are impedance loading values, using inductive and capacitive load case, please take measures to absorb the surge, or it may cause electric life decline, and cut off the defect.

    4. Please avoid install near the strong magnetic field ( such as the transformer, the magnetic around) and near the heating element.

    5. It is forbidden to put the relay in more than using range temperature (-40℃~85℃) environment for a long time, otherwise easy to cause the plastic parts aging and impact product performance.

    6. Please avoid adhesion grease and other things on the terminal, please select a suitable connection wire, otherwise it may lead to the terminal abnormal heat, below data for reference:
