4 wheel electric vehicle 250A 300V--800V DC epoxy contactor
Features
Non-polarity: The connection of contact and coil need to be non-polarity.
Epoxy Sealant: Sealed by epoxy resin. It can work in the hostile environment, coil and contact cannot be oxidized and polluted.
Efficient Coil: Optional built-in energy-saving coil, retentive power is only 2-2. 3W, counter electromotive force is 0V.
ROHS authentication is totally meet the requirement of ROHS, It is benefit to body health and the environment protection.
Compare to the similar products, this product is smallest and lightest.
The joint way of the coil is very convenient.
The coil has no counter-force of electromagnetism.
Application:
ODC Series HVDC Contactor are widely used in Electric vehicles, hybrid electric vehicles, fuel cell cars, construction machinery, photovoltaic power generation, wind power, battery charging and discharging system, dc voltage power supply control, and other areas of the dc high voltage.

ATTENTIONS
> Under the resistance load, the rated parameters of the main contact is applicable. If inductive load is adopted and L/R>1ms, the inductive load need to have an protective unit of inrush current in parallel, and also spare room needs to be considered in the designation.
>The coil and the contact of the contactor coil need to be continuously charged with electricity when full loaded. The power need to be connected when cut off. Because of the rise of the temperature, the coil resistance is rising, and the pull-in voltage is also risen. The following measure should be taken: lowering the load voltage and limiting the power-on time.
>The power of drive circuit of the contactor coil must be greater than the coil power of the products. Otherwise, the normally usage of high voltage dc contactor will be influenced.
>The contactor with energy saving board, when connected after 0.15s, the coil starts to switch automatically. Please do not repeat to turn on and turn off. Otherwise, the contactor maybe broken.
>Working Like: ODC series contactors are high voltage switch. It may lost its switch function when in the breakdown mode. Therefore, please do not use it when the condition is not suitable to the contactors. When the working life is almost there, please to change it in time in order not to flame the parts around. The circuit diagram should be well-designed in order to switch off in 1 second.
>Internal Gas and Life: ODC series contactors adopt pressurized cabin contact. The cabin is filled with gas. The life of the gas is decided by the cabin temperature of the contact. Therefore, the environment temperature should be ensured between -40ºC and +85ºC.
>Please do not use it where the magnetic field is high or near the thermal radiation.
>To ensure the main power line is closest to the terminal of the contactors. The plain washer, spring washer, nut and screw need to be installed tightly. The incorrect connection order may cause serve overheating and the fusion of the insulating layer.
>In order not to break the products, the tightening torque of the nuts and screws of contactors needs to be controlled under the following range.
1)Terminals:
M5 screw ODC series 50A: 2 ~ 3N • m;
M6 screw ODC series 100A: 3 ~ 4N • m;
M6 screw ODC series 150A: 5 ~ 6N • m;
M6 screw ODC series 100A: 8 ~ 10N • m;
M6 screw ODC series 100A: 10 ~ 12N • m;
2)Mounting Hole: 2 ~ 3.5N • m.
>Please avoid adhering the oil on the terminal. Please use the following connecting wire. Otherwise, the unusual overheating will be caused:
ODC50A: nominal area should be above 15mm;
ODC100A : nominal area should be above 30mm;
ODC150A : nominal area should be above 40mm;
ODC200A : nominal area should be above 50mm;
ODC250A : nominal area should be above 75mm;
>Please do not use the contactor when it is dropped unexpectedly or over-shocked.
