Current Endurance Curve

Notes:
1) The ambient temperature is 85℃, and the cross-sectional area of the copper bar is ≥90mm². Supply rated voltage to coil;
2) The upper limit of the function temperature is 130℃, which is suitable for long-time working; and the upper limit of the safe temperature is 180℃, which is suitable for short-time working; If the temperature exceeds 180℃,the contactor may fail;

四、 Endurance

八、 Others
1.Please avoid foreign bodies, grease or corrosive liquids in the terminal, otherwise it will lead to abnormal heating at contact terminals.
2. Please avoid installation in strong magnetic field (around the transformers, the magnet) and the heating objects nearby.
3. In order to prevent loosening, please use the washer when installing the relay. Please use the M5 screws to install relay, screw locking torque within 3 N·m～4N·m; Damage may occur when it is beyond the range.
4. Please pay attention to the thickness of copper bars and the value of the torque. If it goes beyond the recommended values in the below table , it will cause thread slide or installation is not tight. To avoid short circuit or fire,it’s not suggest fix two copper bus bar at same side.

Screw on the load terminal	Recommended thickness of copper bus bar	Recommended hole dimension of copper bus bar	Recommended Flatness of copper bus bar	Torque
M8	3~4mm	Ф8.1mm～ Ф8.5 mm	0.1	8N·m～10N·m

5. The rating load of contact is resistive load. Please assure the surge absorption device together with inductive load when using the L/R≥1 ms inductive load (L Load),otherwise it may lead to the decrease of electrical endurance and defective switch.
6. The relay contacts are sealed and filled with gas. When the contact temperature changes, there is internal gas penetrating characteristic.Neputune relays are forbidden to be used at the temperature beyond our suggestion -40 ℃～85 ℃ for long time.
7. In principle, please do not use it when the relay has fallen down.
8. Neptune products are all RoHS2.0 compliant.
9. Neptune reserves the right to change the product. Customers should confirm the version of the specification before purchasing the product.
10. Please contact Neptune Electric (Kunshan) Co., Ltd for more information or support.
